Description
Rating
Minimum Detection Level:
10 V (ac rms or dc) (50 or 60 Hz)
(Using control-supplied whetting Voltage is recommended)
Maximum Applied Voltage:
250 Vac, rms, or 125 Vdc
Nominal Input Loading:
2 mA per input (internally current limited)
Typical Control Response Time:
50 msec (Note: Regulation tasks take priority over input activity.)
Minimum Input Pulse Time:
250 msec
Minimum Transition Time between Pulse Inputs:
250 msec
Input Protection:
Shunting type using MOVs and capacitors. Optical Isolation from input to system.
(1500 Vac, rms)
Hi-Pot Capability:
3.150 kV dc for 1 second, from one input set to the next or from one pin to
chassis, but not across the two terminals of a single input (due to MOVs).

Maximum Pickup Time:
8 msec (not including control response time)
Maximum Release Time:
15 msec (not including control response time)
Output Protection:
Shunting type using MOVs and capacitors. 1500 Vac, rms isolation between coil
