DO818  Dimensions

Width:45 mm (1.77")

Depth:102 mm (4.01"), 111 mm (4.37") including connector

Height:119 mm (4.7")

Weight:0.18 kg (0.4 lbs.)

The DO818  outputs are divided into two individually isolated groups with 16 output channels and one voltage supervision input in each group.

Each output channel consists of a short circuit and over temperature protected high side driver, EMC protection components, inductive load suppression, output state indication LED and optical isolation barrier.

The process voltage supervision input give channel error signals if the voltage disappears. The error signal can be read through the ModuleBus.

DO818  Features and benefits

32 channels for 24 V d.c.

2 isolated groups (RIV50V) with 16 channels and one process voltage supervision input in each group.

The process voltage range is 12-32V dc (nominally 24V dc) and the maximum continuous output current is 0.5A per channel.
