The DO802 3BSE022364R1 is an 8 channel 110 V d.c./250 V a.c. relay (NO) output module for the S800 I/O. The maximum voltage range is 250 V and the maximum continuous output current is 2 A. All outputs are individually isolated. Each output channel consists of optical isolation barrier, output state indication LED, relay driver, relay and EMC protection components.
The relay supply voltage supervision, derived from the 24 V distributed on the ModuleBus, gives a channel signal error and a module warning signal if the voltage disappears. The error signal and warning signal can be read through the ModuleBus. This supervision can be enabled/disabled with a parameter.
Applications
The ABB DO802 3BSE022364R1 module is used across industries to control various types of equipment and systems. Key applications include:
Manufacturing Automation:Controls machinery, actuators, and other devices in production lines.
