Original price was: $7,686.00.Current price is: $4,344.00.

Product Introduction

How often do field contact failures or welded relay tips force unnecessary trips on heavy duty gas or steam turbine panels? The GE IS200WROBH1A is engineered specifically to deliver fault-tolerant electromechanical relay switching across GE Mark VIe turbine control cabinets.

Instrument and control technicians rely on the GE IS200WROBH1A to actuate high-priority field solenoids, trip coils, and alarm annunciators. Designed for seamless operation alongside Mark VIe I/O packs, the module provides isolated contact outputs that withstand harsh inductive kickback in power plant switchyards.

    Key Selling Points & Differentiators

    • Direct plug-and-play interface with Mark VIe relay output packs (such as YRRO or PRRO) via standard high-density D-shell cables.
    • Complete bench verification report covering contact resistance and relay coil pickup time supplied with every unit shipped.
    • Includes 18 high-reliability relays with integrated snubber protection to suppress voltage spikes during coil de-energization.
    • Not recommended for high-speed pulse-width modulation (PWM) or continuous solid-state switching applications requiring kilohertz response.
    • Manufactured in strict accordance with IEEE 1613 standards for surge withstand capability in electric utility substations.

     

    Quality Transparency SOP

    1. Incoming Inspection: Serial number check against GE manufacturer records; physical inspection of relay housings, barrier terminal blocks, D-shell connector pins, and PCB trace integrity.
    2. Live Functional Test: Connected to a Mark VIe simulator rack. Verified 24 VDC coil energization, contact closure continuity across all 18 form C channels, and status LED illumination. Kept under continuous resistive contact load testing for 24 hours while logging internal heat rise.
    3. Electrical Parameter Tests: Megger insulation testing performed at 500 VDC (>10 MΩ target) between contact groups, coil circuits, and ground.
    4. Firmware / Revision Verification: Verified board hardware revision suffix (H1A), onboard diode orientation, and trace bridge configurations against OEM engineering sheets.
    5. Final QC + Packaging: QC approval sign-off completed, board sealed inside a static-shielding ESD bag, wrapped with heavy foam cushioning, and boxed in a reinforced shipping carton with a dated QC certificate.
