3-4.8 GENII PI REM Pulse Input Module
The GENII PI REM Pulse Input Module (Figure 3-12) is powered by 24VAC ±10% @ 50/60 Hz. Power
Consumption is 4 VA maximum.
The GENII PI REM provides 5 opto isolated digital inputs to sense pulsed signals from field equipment.
The voltage detection range is 12 to 24VDC. The GENII PI REM detects pulses with a minimum on time
of 20ms, with a minimum off time of 20ms, which gives a maximum of 25 pulses per second.
