OVERVIEW
TheACT-1B is an economical and easy to use digital tachometer that displays
rotational speed directly in RPM or RPS on a 5-digit red 0.56” high LED
display using a speed sensor providing a single (or multiple) pulse(s) per
revolution. The number of pulses per rev is factory set at time of ordering and
can be user programmed from 1 to 999 using the optional USB Programming
Cable and PM Remote Software. Power may be either universal 100 to 240
Vac (50/60Hz), or optionally, 12 Vdc or 24 Vdc isolated. TheACT-1B accepts
input signals from optical, proximity, magnetic, infrared or laser sensors, or
direct TTL or external ac inputs. The ACT-1B is suitable for panel mounting
or bench top use with convenient screw terminal connections on the rear
panel of the instrument.
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
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.
WARNING: Do not over tighten the mounting screws.
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.
Figure 2 ACT-1B Rear Panel
If the unit is ac powered (100 - 240 Vac), connect the Live (Hot) wire to the
terminal marked L+ and the Neutral (Return) wire to the terminal marked N-.
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-.

USB Programming Cable and Software
The 3.5 mm connection “hole” in the center bottom of the rear panel is for the
optional USB Programming Cable (p/n 6180-031), which comes withWindows™
compatible PM (Panel Meter) Remote Software. The cable and software
combination allows the user to configure: operation mode, analog output scaling,
decimal places, display update rate and pulses per input. The user can also view real
time data in digital format and/or through Microsoft®Excel. Software instructions
are included with the software downloaded from monarchinstrument.com.
SENSOR CONNECTIONS
A speed sensor (not included) is connected to the terminals under the section
labeled INPUT on the rear panel. Refer to Figures 2 and 3.
Connections and their functions are as follows:
+VA Positive +12 Vdc to provide power to optical, laser, infrared
or amplified magnetic sensors. Maximum load is 75 mA dc.
Optionally 5 or 24 Vdc supply may be ordered.
PX+ Positive +12 Vdc supply for use with two-wire proximity
sensors. Maximum load for proper operation with two-wire
sensors is 25 mA.
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.
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
TheACT-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 or
may be user programmed using the optional USB Programming
Cable and PM Remote Software.
The Current or Analog Outputs are connected to the terminals in the section
labeled ANALOG OUTPUT OPTION on the rear panel. The actual output
is marked. The Pulse Output is connected to the terminals under the section
labeled OUT on the rear panel.
CAUTION: The IO or AO COM may NOT be isolated from the other
COM connections.

Current Output Option (IO)
The current output is 4 to 20 mA. This output is a current source and has
a 12 Vdc internal compliance voltage. (Optional 24 Vdc may be ordered).
Typical connections are as follows: (See Figure 4.)
Connect the Positive side of the load to the terminal marked OUT
and the other (Negative) side of the load to the terminal marked
COM.
Do not use an external voltage supply.
Figure 4 Current Output Option Connections
NOTE: With the internal 12 Vdc compliance voltage the maximum
load for the current loop is 500 Ohms.
If the optional 24 Vdc compliance option is ordered the
maximum load will be 1000 Ohms.

6
Analog Output Option (AO)
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.
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 range may be programmed using the optional USB
Programming Cable and PM Remote Software.
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.
NOTE: The polarity of the optional pulse output can be set by the user
using the optional USB Programming Cable and PM Remote
Software.
