ABB DO802 Digital Output Relay Module

Description

The ABB DO802 is a robust digital output relay module designed for ABB AC 800M controllers and the S800 I/O system. It delivers 8 individually isolated relay outputs for safe and reliable switching in industrial environments. Each channel provides a normally-open (NO) contact suitable for both DC (up to 110 V) and AC (up to 250 V) loads. The module features output status indicators and an Output State Preservation (OSP) function, which sets outputs to a predefined state in case of errors. Its compact DIN-rail design and hot-swap capability simplify maintenance and reduce system downtime.
