ABB DO840 3BSE020838R1 Digital output unit

Description

This module has 16 digital outputs. The maximumcontinuous output
current per channel is 0.5 A. The outputs are currentlimited and
protected against over temperature. The outputs are divided into two
groups with eight output channels and one voltage supervision
inputin each group. 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 optical isolation barrier.

Features and benefits
16 channels for 24 V d.c. current sourcing outputs
2 isolated groups of 8 channels with process voltage supervision
Advanced on-board diagnostics
Output status indicators
OSP sets outputs to predetermined state upon error detection
Redundant or single applications
Currentlimited and over-temperature protection
