System components: Digital input/output module SFC432

The following combined voltage input and relay output modules are available: SFC432 (1 group of 8 24 VDC inputs and 1 group of 4 NO relays) SFC435 (1 group of 8 24 VDC inputs and 1 group of 4 NC relays) SFC438 (1 group of 8 24 VDC inputs and 1 group of 2 NO and 2 NC relays) The modules with combined DC Inputs and Relay Outputs are designed to drive relays, pilot lamps, valves and other loads up to 5 A. The module senses the DC input voltage and converts it to a true or false logic signal. Each module has 1 group of 8 optically isolated 24 VDC inputs and 4 relay outputs, see above. The relays can drive loads ranging from 0 to 30 VDC or from 0 to 30 VAC. Two screw terminals are reserved for each relay output, which are mutually isolated from each other.
