Page 4: Overview
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 time of ordering and can be user programmed from 1 to 999 using the optional USB Programming Cable and PM Remote Software. -

Figure 3 Sensor Connections 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 or may be user programmed using the optional USB Programming Cable and PM Remote Software. -
Page 8: Current Output Option (Io)
4.1 Current Output Option (IO) 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: (See Figure 4 below.) 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. -
Page 9: Analog Output Option (Ao)
4.2 Analog Output Option (AO) 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. -
