OVERVIEW
The ACT-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 the 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 V ac (50/60H2), or optionally, 12 V dc or 24 V dc isolated. The ACT-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 benchtop use with convenient screw
terminal connections on the rear panel of the instrument.
If specified at the time of order placement, the ACT-1B may be equipped with
either an optional 4 to 20 mA current output (10) or 0 to 5 V dc 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 [91 mm x 44 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 specifications
indicated on the rear panel. Refer to Figure 2 below.
- If the unit is AC powered (100-240 V ac), 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 (PN 6180-031), which comes with Windows’™
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 Excel®. Software
instructions are included with the software downloaded from
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 V dc to provide power to optical, laser, infrared, or amplified magnetic sensors. Maximum load is 75 mA dc. Optionally 5 or 24 V dc supply may be ordered.
- PX+: Positive +12 V DC supply for use with two-wire proximity sensors. The 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 V AC to 50 V AC. (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. The typical input impedance is 10 kiloohms.
- COM: Common or Negative connection for both signal and power from most sensors.
Refer to Figure 3 (next page) for the 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 (10) 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 10 or AO COM may NOT be isolated from the other COM connections.
Current Output Option (10)
- The current output is 4 to 20 mA. This output is a current source and has a 12 V DC internal compliance voltage. (Optional 24 V dc may be ordered)
- Typical connections are as follows:.
- 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.
Note: With the internal 12 V DC compliance voltage, the maximum load for
the current loop is 500 ohms.
If the optional 24 V DC compliance option is ordered, the maximum load will be
1000 ohms.
Analog Output Option (A0)
The analog output is 0 to 5 V dc.
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 the terminal marked +P and 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.

APPENDIX A – Serial Programming Commands
Programming the unit requires the optional USB Programming Cable with
associated PM Remote Software and a PC running Windows XP or later with an
available USB port.
All serial commands are @ then two or more characters or words separated by a
delimiter “/”. One or two numbers follow some commands. All valid commands
respond immediately with an “OK” or data, or “ERR” if incorrect.
The default baud rate is 9600.
