Why Choose the ABB OBOA1000-230VUC Optocoupler?

The ABB OBOA1000-230VUC is a compact and reliable solid-state optocoupler designed to provide electrical isolation between control circuits and AC loads in industrial automation and control systems. As part of the ABB R600 interface relay and optocoupler series, it provides a practical interface between control equipment such as PLCs and connected field devices.

This optocoupler uses a Triac output for switching AC loads while providing galvanic isolation between the control input and output circuit. The integrated LED provides a clear indication of the switching state, while screw terminals provide straightforward electrical connections for control panel installation.

With a rated control supply voltage of 230 V AC/DC and an output suitable for 24–400 V AC switching at up to 1 A, the OBOA1000-230VUC is suitable for interfacing industrial control systems with a wide range of AC loads and automation equipment.
