The 750-515 four-channel digital relay output module features compact 12-mm housing and is designed to maximize space in the control cabinet. As a component of the fieldbus-independent Wago-I/O-System, the module can be used universally with any Wago PLC or coupler. It can be used with multiple voltage potentials (250 Vac/30 Vdc) and offers 2 A per electrically isolated channel when all four are employed or 5 A when used as single channel for high-current applications. Onboard indication facilitates troubleshooting.
