07 DO 90-S GJR5250800R202 | ABB Binary Output Safety Module

Product Overview

The ABB 07 DO 90-S (GJR5250800R202) is a safety-related binary output module with 8 electrically isolated outputs. It operates on 24V DC and delivers up to 0.5A per channel with 4A total module current. Designed for safety-critical applications, it features electronic short-circuit protection and inductive load limiting.

Core Functionality

The 07 DO 90-S controls 8 binary output channels with electrical isolation as a group. It limits inductive interrupt voltages using diodes and supports inductive loads up to 0.5Hz switching frequency. The module monitors 0-signal output levels; if an output exceeds 8V while in state 0, the module shuts down and generates an error. Test signals under 1ms verify output integrity.

Technical Specifications

Installation Guide

Mount the 07 DO 90-S on DIN rail. Connect 24V DC process voltage (UP) and supply voltage (L+) per VDE551 requirements. Wire outputs to field devices using conductors up to 2.5 mm². Tighten terminals to 0.5 Nm maximum. Use shielded cable for runs up to 1000m, unshielded up to 600m. Ensure supply voltages rise to at least 19V within 40ms after power-up.

Engineering Advantages

This safety-related module delivers 8 isolated outputs with electronic short-circuit protection. Diode limiting handles inductive loads safely. The module monitors 0-signal levels and shuts down on fault detection. Buffered voltage interruption for L+ exceeds 10ms. CE safety certification (S-CE) ensures compliance with safety standards.
