GE IS200SRLYH2ABA Mark VIe Relay Output Terminal Board | Discrete I/O

Product Description

Overview

The GE IS200SRLYH2ABA is a Discrete Relay Output Terminal Board designed for the Mark VIe Speedtronic control system. It provides a robust interface for switching field devices via relay outputs in turbine control, power generation, and heavy industrial applications. The board supports multiple voltage levels and is engineered for reliable operation in hazardous or high-vibration environments.

Key Features

• 12 Form-C Relay Outputs: Each relay offers both Normally Open (NO) and Normally Closed (NC) contacts for flexible field wiring.

• Multiple Voltage Support: Compatible with 24V, 48V, and 125V DC circuits.

• High-Density S-Type Layout: Compact footprint allows double-stacking in control cabinets for efficient space usage.

• Galvanic Isolation: Protects sensitive Mark VIe electronics from field-side surges and electrical noise.

• Rugged Industrial Design: Rated for operation between -30°C and +65°C, suitable for high-vibration and harsh industrial environments.

• Diagnostic Feedback: Provides isolated relay status outputs to verify physical switching events.

• Hazardous Location Certification: UL E2067685 Class 1 Zone 2 Group IIC, ANSI/ISA-12.12.01-2015 Class I Division 2 Groups A/B/C/D.

Technical Specifications

Applications

• Switching solenoid valves, motor starters, or alarm indicators in turbine and process control systems.

• Single-channel output reliability where triple modular redundancy is not required.

• High-density I/O installations in compact control cabinets.

FAQ

Q: Can this board operate with multiple voltage outputs simultaneously?
A: Yes, it supports 24V, 48V, and 125V DC, but each relay channel must be wired according to the voltage rating.

Q: Is the IS200SRLYH2ABA certified for hazardous locations?
A: Yes, it meets UL E2067685 and ANSI/ISA-12.12.01-2015 standards for Class I Division 2 environments.

Q: How do I verify that relays have actually switched?
A: The board provides isolated feedback contacts for each relay, allowing confirmation of physical switching through the I/O pack.

Q: Can this module be stacked in compact cabinets?
A: Yes, the S-Type layout supports double-stacking without expanding the cabinet footprint.
