Once the current passes through the input point, the result is logical 1 in the input status table (%I). Users can power field equipment to operate, or they can use an isolated +24 VDC output to power a limited number of DC inputs. The IC693MDL634 Input voltage ranges from 0 to +30 volts DC, with a rated input current of 7 mA (typical value). It operates at 11.5 to 30 volts DC in the open state and 0 to +5 volts DC in the off state. The minimum on-state current is 3.2 mA and the maximum off-state current is 1.1 mA.
