These Click series stackable micro brick PLCs feature higher amperage relay output modules and an eight-point input simulator module. The C0-04TRS-10 is a four-point, 10 A per point isolated relay output module with four Form A (SPST) relays and four isolated commons. The operating voltage range is 6-24 Vdc/6-240 Vac. The C0-08TR-3 is an eight-point, 3 A per point relay output module with eight Form A relays and four isolated commons. The operating voltage range is 6-27 Vdc/6-240 Vac. The C0-08SIM input simulator module provides eight toggle switches to simulate input devices, eight logic side green status LED indicators and an LED power indicator.
