Answer Posted / carl_ellis
The spec sheets on my desk have these specs:
for an AC voltage digital input:
2 mA nominal @ 230 VAC, 50 Hz
for a DC voltage digital input:
2.3 mA @ 12 VDC
6.9 mA @ 24 VDC nominal
for a dry contact digital input (internal 15Vdc source):
2.6 mA nominal
Interviewees should be able to convert from milliamps to amps.
Normally, power (watts) is 'consumed'.
Current (amps) is a 'draw' on the power supply.
