1. Function
The SDM-CD16AC has 16 AC/DC relay control ports (see Figure 1). Each relay
port can be controlled by a datalogger or controlled manually with a manual
override toggle switch.
The toggle switch has three positions; "ON" and "OFF" for manual override,
and "AUTO" for datalogger control. In the "ON" position, the common
(COM) and normally open (NO) contacts are closed (see Figure 2). In the
"AUTO" position, the state of the relays are controlled by the datalogger
control ports.
The SDM-CD16AC is a synchronously addressed datalogger peripheral.
Three ports on the datalogger are used to address the SDM-CD16AC, then
clock out the desired state of each of the 16 control ports. Up to 16 SDM-
CD16ACs may be addressed, making it possible to control a maximum of 256
ports from the three datalogger ports.
In CRBasic, the SDMCD16AC instruction is used to control the SDM-
CD16AC. In Edlog, either I/O Instruction 104 (CR10(X), CR23X, 21X) or
Instruction 29 (CR7) is used.
Ensure that the datalogger contains the appropriate instruction
prior to system deployment. The SDM-CD16AC is not
compatible with our CR200-series, CR500, or CR510
dataloggers.

3. Power Considerations
The SDM-CD16AC power requirements are large compared to most CSI
products. For most applications an external power supply (see Figure 3) is
recommended to power the SDM-CD16AC.
For some applications it may be convenient to use the datalogger supply to
power the SDM-CD16AC (see Figure 3). For long-term applications, the lead
acid power supply available with CSI dataloggers should be used, allowing the
batteries to be float charged. It is not recommended that the datalogger
alkaline supply be used to power the SDM-CD16AC for long term
applications.
If the datalogger lead acid supply is used, the number of SDM-CD16AC's that
can be powered is limited by the 300 mA current sourcing capability of the
wall charger. With a continuous 6 mA current drain per SDM-CD16AC and
45 mA per active LED, a maximum of 6 LEDs may be powered by the
datalogger, after which, more current is drawn than can be sourced by the wall
charger. If this condition is maintained, it will ultimately lead to battery deep
discharge, requiring new batteries.

On a CR7, SDMs connect to the ports at the upper right corner
of the 700X Control Module. On a CR9000X, SDMs connect to
the ports on the CR9032 CPU Module, and on a CR9000, SDMs
connect to the ports on the CR9080 PAM Module.
NOTE
If the 21X power supply is used to power the SDM-CD16AC, all low level
analog measurements (thermocouples, pyranometers, thermopiles, etc.) must
be made differentially. This is a result of slight ground potentials created
along the 21X analog terminal strip when the 12 V supply is used to power
peripherals. This limitation reduces the number of available analog input
channels and may mandate an external supply for the SDM-CD16AC.
4. Installation
•
The SDM-CD16AC must be installed in an enclosure that provides a
pollution degree 2 environment (normally, only nonconductive pollution.
However, a temporary conductivity caused by condensation may be
expected). All Campbell Scientific enclosures meet this requirement.
•
•
•
•
•
Use copper conductors only.
Wire Range: 30 − 14 AWG
Tightening Torque: 5 − 7 in./lb.
Use minimum 60/75 degree C wire.
Input power must be connected to a class 2 supply only. All Campbell
Scientific power supplies meet the class 2 supply requirements.
The order in which connections are made is critical.
Always connect 12 V first, followed by ground, then Control
Ports.

Cables connecting the terminals of the datalogger and
CAUTION
SDM device should be kept as short as possible to
minimize the risk of corruption of the signals and damage
from induced surges. Where long cable runs (>3 m) are
unavoidable and the cables run outside, some extra
protection may be required for the SDM control terminals.
Please contact Campbell Scientific for further advice.
When connecting wires to the SDM signal terminals please
ensure they are at ground potential before making the
connection, e.g. by touching them to the earth terminal.
For datalogger connections, see Table 1.
Multiple SDM-CD16AC's may be wired in parallel by connecting the
datalogger side of one SDM-CD16AC to the next. For CR10 and 21X
dataloggers, the total length of the cables connecting the SDM-CD16AC's
should not exceed 20 feet.
Total cable lengths in excess of 20 feet will adversely influence
communication performance. For CR7 dataloggers, the total cable length
should not exceed 600 feet.

Figure 2 shows how the switches in each channel operate. NO means
“normally open”, NC means “normally closed”. COM means “common” to
NO and NC.
In most applications, the SDM-CD16AC acts as a switch (controllable break)
in one wire of the circuit powering the controlled device. One side of this
break may have power (hot). Figure 4 shows an example.

4.1.3 Motor Control
The CD16AC is a UL approved Start/Stop motor controller. In the figure
below, a typical 5 Amp 115 VAC relay contact circuit shows how to control a
three phase motor starter in a Motor Control Center (MCC). Typically, the
CR10X will automatically command the appropriate relay to energize the
motor starter. The relay in the CD16AC will remain latched until the CR10X
program commands that the motor be turned off, at which time the relay will
open the circuit to the motor starter and the motor will stop.
The CD16AC can be used to control three phase pump motors, air blowers,
and large control valves in the same fashion.

6. Datalogger Programming
In CRBasic, the SDMCD16AC instruction is used to control the SDM-
CD16AC. Dataloggers that are programmed with CRBasic include our
CR800, CR850, CR1000, CR3000, and CR5000.
Edlog Instruction 104 is used by the CR23, 21X, and CR10(X) to control the
SDM-CD16AC, and Edlog Instruction 29 is used by the CR7. SDM-CD16AC
outputs that are to be controlled by the datalogger must have the toggle switch
in the AUTO position.
6.1 CRBasic Programming
SDMCD16AC
Syntax
SDMCD16AC (Source, Reps, SDMAddress)
Remarks
A port on an SDM-CD16AC is enabled/disabled (turned on or off) by sending
a value to it using the SDMCD16AC instruction. A non-zero value will enable
the port; a zero value disables it. The values to be sent to the CD16AC are held
in the Source array.
The SDMCD16AC instruction has the following parameters:
Source: The Source parameter is an array which holds the values that will be
sent to the SDM-CD16AC to enable/disable its ports. An SDM-CD16AC has
16 ports; therefore, the source array must be dimensioned to 16 times the
number of Repetitions (the number of SDM-CD16AC devices to be
controlled). As an example, with the array CDCtrl(32), the value held in
8

SDM-CD16AC 16 Channel AC/DC Controller
CDCtrl(1) will be sent to port 1, the value held in CDCtrl(2) will be sent to
port 2, etc. The value held in CDCtrl(32) would be sent to port 16 on the
second SDM-CD16AC.
Reps: The Reps parameter is the number of SDM-CD16AC devices that will
be controlled with this instruction.
SDMAddress: The SDMAddress parameter is used to define the address of
the CD16AC that will be controlled with this instruction. Valid SDM addresses
are 0 through 14. Address 15 is reserved for the SDMTrigger instruction. If the
Reps parameter is greater than 1, the datalogger will increment the SDM
address for each subsequent device that it communicates with.
CRBasic dataloggers use base 10 when addressing SDM devices.
Edlog programmed dataloggers (e.g., CR10X, CR23X) used
base 4 for addressing (see Table 2).

SDM-CD16AC 16 Channel AC/DC Controller
The number of SDM-CD16ACs to be addressed is defined by the Reps
(repetitions) parameter. Each Rep will sequentially address (00, 01, 02,...32,
33) SDM-CD16ACs starting with the address specified in parameter 2
(Instruction 29 parameter 3).
For each Rep, the 16 ports of the addressed SDM-CD16AC are set according
to 16 sequential Input Locations starting at the Input Location specified in
parameter 3 (Instruction 29 parameter 5). Any non-zero value stored in an
input location activates the associated SDM-CD16AC port. A value of zero
(0) deactivates the port For example, assuming 2 Reps and a starting Input
Location of 33, OUTPUT 1 through 16 of the first SDM-CD16AC are set
according to Input Locations 33 through 48, and OUTPUT 1 through 16 of the
second SDM-CD16AC are set according to Input Locations 49 through 64.
For Instruction 29, the Device (parameter 2) specifies what type of
synchronously addressed peripheral is to be addressed. The Device code for
an SDM-CD16AC is 2.
For Instruction 29 only (CR7), the Card parameter 4 specifies which 725
Excitation Card is being used for the Control Port signals. The Reps parameter
does not advance beyond the specified Card, requiring another Instruction 29
for each 725 Excitation Card used.
7. Theory of Operation
The SDM-CD16AC is a synchronously addressed peripheral. C2 and C3,
driven high by the datalogger, initiate a cycle. While holding C3 high, the
datalogger drives C2 as a clock line and C1 as a serial data line. The
datalogger shifts out a data bit on C1 (LSB first) on the falling edge of the C2
clock. The SDM-CD16AC shifts in the C1 data bit on the rising edge of the
C2 clock.
The first 8 bits clocked out represent the SDM-CD16AC address. If the
address matches the SDM-CD16AC's address, the SDM-CD16AC is enabled.
If enabled, the next 16 bits are shifted into the SDM-CD16AC, each bit
controlling one port, the first of which controls OUTPUT1.
When the 16 control bits are clocked in, C2 is held high while C3 is pulsed low
then high to latch the control bits. The datalogger then lowers both C3 and C2
to complete the cycle.
8. Program Examples
8.1 CRBasic Example
In the following CR1000 program example, a counter is used to fill an array
called Src( ) that will control two SDM-CD16ACs.

8.2 Edlog Example
The example is written for the CR10(X) Measurement and Control Module.
The program concepts presented are the same for the CR23X, 21X, and CR7
dataloggers with minor program code changes.
In this example, the SDM-CD16AC is used to control the temperature between
23° and 28°C in each of 5 greenhouses. In each green house the SDM-
CD16AC controls a heating unit, a refrigerating unit, and an air mixing fan
according to the following conditions.
Heating unit: Activate when temperature < 23.5°C. Deactivate when
temperature > 25.5°C
Cooling unit: Activate when temperature > 27.5°C. Deactivate when
temperature < 24.5°C
Mixing fan: Activate whenever the heating or cooling units are activated.
Activate for 5 minutes out of every 15 minutes.
The program assumes the temperature measurements have been made, and the
average temperature for each greenhouse is computed and residing in Input
Locations 1 through 5.
