General Electric Mark VIe IS230TRLSH2B Relay Output Module

Description

The General Electric IS230TRLSH2B is a specialized relay output terminal board module designed for the Mark VIe control system platform. This Relay Output Module interfaces with control processors to safely drive field solenoids, control valves, motor starters, and external interlock circuits across heavy industrial environments. Operating as a component within the distributed control architecture, it receives digital commands from the system controller and converts them into physical, isolated dry contact closures or voltage switching states. It is engineered specifically for system compatibility within large-scale utility and turbine control frameworks, providing robust physical separation between low-voltage microelectronic control loops and high-voltage field execution circuitry.

Features

• Built for reliable physical and electrical galvanic isolation within the modular framework
• Designed to accept high-speed logic state signals from upstream control layers
• Equipped with rugged on-board relays configured for continuous operational duty
• Features terminal block junctions directly on the board assembly for secure field loop routing
• Integrates seamlessly with multi-channel architecture to minimize cabinet hardware footprints

Applications

• Distributed Control Systems (DCS) for gas, steam, and hydro turbine regulation
• Solenoid valve control and auxiliary pump startup staging
• Safety interlock processing and remote equipment trip circuits
• Heavy industrial power plant, manufacturing, and critical system infrastructure automation

Installation Guidelines

Cabinet Orientation & Mounting

Secure the module onto its designated backplate or carrier structure inside the control cabinet. Ensure the mounting fasteners are fully tightened to ground the underlying metal chassis panel and isolate the board from excessive high-frequency structural vibration.

Cable Shielding & Routing

Route all digital signal cables separate from heavy AC power lines to protect against inductive cross-coupling and electrical noise. Terminate field wire shields only at the specified system ground point on the board frame.

Connection Torques

When tightening the terminal block screws for field loops, torque them according to standard industrial terminal specifications to prevent loose contact junctions or intermittent continuity dropouts during thermal cycling.
