Overview
The Omron 3G2A3-OD411 is a discrete relay output expansion module for Omron SYSMAC PLC systems. This 8-point output module provides reliable DC switching control in industrial automation applications where digital outputs must drive relays or low-power DC loads. With input voltage ranging from 12 to 48VDC and a 0.5A per-point current rating, the 3G2A3-OD411 delivers steady-state output control for motion control, solenoid activation, lamp indication, and alarm circuits. Though discontinued by the manufacturer, surplus units remain in high demand for system maintenance and expansion on legacy SYSMAC installations.
