ABB DO880 3BSE028602R1 Digital Output Module

The DO880 is a 16 channel 24 V digital output module for single or redundant application. The maximum continuous output current per channel is 0.5 A. The outputs are current limited and protected against over temperature. Each output channel consists of a current limited and over temperature protected high side driver, EMC protection components, inductive load suppression, output state indication LED and an isolation barrier to the Modulebus.

The module has 16 channels in one isolated group for 24 V DC current source outputs. Has loop monitoring, short circuit and open load monitoring with configurable limits. Output switching diagnostics without pulsing on the output. Degraded mode for normally powered channels, short circuit current limiting and switch overtemperature protection.
