ABB DO810 System 800xA hardware selector

This module has 16 digital outputs. The output voltage range is 10 to

30 volt and the maximum continuous output current is 0.5 A. The

outputs are protected against short circuits, over voltage and over

temperature. The outputs are divided into two individualy isolated

groups with eight 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. The outputs are current limited and protected against

over temperature. If the outputs are overloaded the output current

wi l be limited.
