Digital input minimum frequency is 1 Hz and maximum frequency is 100 kHz. Digital signals are
updated 10 times per second (10 Hz). Digital inputs are low when the signal is
≤
1.9 VDC or the
resistance to ground is
≤
375
Ω
, and are otherwise high. Maximum output high/low and low/high
transition period is 5.0 µS. Digital inputs can also be configured as discrete inputs.

GEA System ID Program
The GEA SYSTEM ID PROGRAM 1 (P701, Pin 9) and GEA SYSTEM ID PROGRAM 2 (P701, Pin 10)
should be left open.
A.4.8
Remote Power Off
The GEA 71 powers down upon receiving the remote power-off signal. Power-off action is triggered by
voltages
≥
10.0 VDC. Remote power-off input is connector P701, pin 77.
