OPTIONS

OVERVIEW
4 to 20 mA current output
0 to 5 Vdc analog output
ACT-1B Digital Tachometers display rotational speed directly in RPM on a
5 digit red LED display using a speed sensor providing a single pulse per
revolution (Model ACT-1B), 10 pulses per revolution (Model ACT-1B-10)
or 60 pulses per revolution (Model ACT-1B-60). Power may be either 115
Vac or 230 Vac (50/60 Hz), or optionally, 12 Vdc to 15 Vdc. The ACT-1B
Series accepts input signals from optical, proximity, magnetic, infrared or
laser sensors, or direct TTL or external ac inputs. All models are suitable for
panel mounting or bench top, with convenient screw terminal connections
on the rear panel of the instrument.
AO:
NOTE: Full scale RPM must be specified for the above
options when ordering.
PO:
0 to 5 V TTL compatible pulse output
NOTE: Pulses out per revolution equal pulses in
per revolution.
CAL-N.I.S.T.
N.I.S.T. Traceable Certificate of Calibration
If specified at time of order placement, the ACT-1B may be equipped with
either an optional 4 to 20 mA current output (IO) or 0 to 5 Vdc analog
output (AO) proportional to speed, and/or a TTL pulse repeater output (PO).
INSTALLATION and POWER
The ACT-1B enclosure is a standard 1/8 DIN size requiring a 3.58” wide by
1.74” high (91x44 mm) mounting hole.

Installation
Analog Output Option (AO)
Remove the mounting clips, if fitted, and install the unit into the panel from
the front. From the rear of the unit, install the mounting clips on each side
and tighten the mounting screws against the rear of the panel.
The analog output is 0 to 5 Vdc.
Connect the Positive side of the signal to the terminal marked OUT,
and the Return side of the signal to the terminal marked COM.
WARNING: Do not over tighten the mounting screws.
NOTE: If your ACT-1B is equipped with either a current output or
an analog output, the full-scale output has been factory preset
to the speed range specified at the time of purchase. The output
is linear in 4096 discrete steps over its designated range.
Power
Power to the unit is connected to the terminals under the section labeled
POWER on the rear panel. Be sure the power supplied matches the
specification indicated on the rear panel. Refer to Figure 2 below.
Pulse Repeater Output Option (PO)
The Pulse Repeater output provides a conditioned TTL positive going
5 V pulse out for each pulse in.
Connect the Positive signal wire (+5 V pulse) to terminal marked +P
and the Return to the terminal marked COM in the rear panel section
labeled OUT.
Figure 2 ACT-1B Rear Panel
If the unit is ac powered (115 Vac or 230 Vac), connect the Live (Hot) wire
to the terminal marked L+ and the Neutral (Return) wire to the terminal
marked N-. Connect the Ground (Earth) wire to the terminal marked GND.
NOTE: For full compliance with CE specifications, the Ground (GND)
connection must be made.

If the unit is dc powered, connect the dc supply Positive to the terminal
marked L+ and the dc supply Negative or Common to the terminal
marked N-.
NOTE: On dc powered units, no connection is required to the terminal
marked GND.
SENSOR CONNECTIONS
A speed sensor (not included) is connected to the terminals under the
section labeled INPUT on the rear panel. Refer to Figure 2 and 3.
Connections and their functions are as follows:
+5V Positive +5 Vdc to provide power to optical, laser, infrared or
amplified magnetic sensors. Maximum load is 75 mA dc.
Figure 4 Current Output Option Connections
PX+ Positive +8 Vdc supply for use with two wire proximity
sensors. Maximum load for proper operation with two wire
sensors is 5 mA.
NOTE: The voltage source you use will determine the maximum
resistance of the load. This voltage is referred to as the
compliance voltage and must be equal to the maximum
current through the load (20 mA) multiplied by the load
resistance, plus 4 Vdc. For example, if the load is 1000 ohms,
the external voltage source must be:
SIG Positive input signal from the speed sensor. Accepts TTL pulses
or ac signals, unipolar and bipolar, from 1.5 Vac to 50 Vac.
(Contact the factory for increased sensitivity.) Connect the
signal wire from three wire sensors or the positive side of two
wire magnetic sensors to this terminal. Typical input
impedance is 10 Kohms.
(1000 ohms x 0.020 A) + 4 Vdc = 24 Vdc
Thus, for an external source voltage of 24 Vdc, the
maximum loop load (the sum of all resistances in the loop) is
1000 ohms. 24 Vdc is, in fact, a recommended voltage. The
voltage supplied by an external source should NEVER
exceed 40 Vdc. The ACT-1B 15 Vdc internal voltage source
(+VA) permits a maximum load resistance of 500 ohms.
COM Common or Negative connection for both signal and power
from most sensors.

Refer to Figure 3 for connection of Monarch standard sensors. The
connections are typical for these types of sensors.
OUTPUT OPTIONS
The ACT-1B may be equipped with either a Current Output (IO) or an Analog
Output (AO), and/or a TTL Pulse Output (PO).
NOTE: Full scale RPM settings must have been specified when ordered;
these options are not field programmable.
The Current or Analog Outputs are connected to the terminals in the section
labeled ANALOG OUTPUT OPTION on the rear panel. The Pulse Output
is connected to the terminals under the section labeled OUT on the rear
panel.
Shield to COM
Shield to COM
CAUTION: The IO or AO COM is NOT isolated from the other
COM connections.
Current Output Option (IO)
The current output is 4 to 20 mA. This output is a current sink and
requires a source voltage. A 15 Vdc internal source is provided at the
terminal marked +VA. When using an external voltage source, the
current from that source is regulated by the ACT-1B.
Figure 3 Sensor Connections
Typical connections are as follows: (See Figure 4.)
When using the ACT-1B internal +15 Vdc source, connect the
Positive side of the load to the terminal marked +VA and the other
side of the load to the terminal marked OUT.
When using an external voltage source, connect the Negative side
of the external source to the terminal marked COM, the Positive
side of the supply to the Positive side of the load, and the other
side of the load to the terminal marked OUT.
