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.
