Table 12. Contact I/O option module input ratings
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).

Description Rating
Maximum Switching Voltage: 250 Vac, rms or 125 Vdc
Maximum Switching Loading: Refer to Figure 53.
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
and contacts
Hi-Pot Capability: 3.150 kV dc for 1 second from one output to the next or from one pin to chassis,
but not across two terminals of a single output (due to output protection).
Fusing: Outputs are not internally fuse-protected. Customer-supplied fusing is
recommended.
