GE IS420YDOAS1B Discrete Output I/O Module

This module handles critical control tasks in industrial environments, switching electrical circuits on/off with precision. We’ve seen it deployed in power plants for turbine control, in manufacturing lines for machine sequencing, and in chemical facilities managing valve operations. Its 12 relay channels support both AC and DC loads, making it versatile for different system architectures.

Technical Specifications

Field Applications

A Texas-based refinery recently upgraded their burner management system using this module. They needed reliable discrete control for fuel valves and ignition systems – the IS420YDOAS1B’s galvanic isolation between channels prevented electrical noise from affecting critical safety circuits.

Our clients in the automotive sector often pair this module with GE’s VMIVME-7807 communication boards for high-speed production line control. In HVAC systems, it’s commonly integrated with IS230SRTDH2A temperature controllers for zone management.
