Overview

The GE IS200SRLYH2AAA is a Simplex Relay Output Terminal Board used in the GE Mark VIe control system. It is designed to control high-power field devices such as motors, solenoid valves, and alarms via digital commands. This board houses 12 relay outputs, functioning as physical switches that interface with the control system. The board is commonly used in applications requiring direct control of power devices where simplex configuration (single control point) suffices, offering a straightforward, cost-effective solution for industrial systems.

Key Technical Specifications

1. Relay Output Channels & Types

• Channels 1–6: Form-C (SPDT) contacts with Normally Open (NO), Normally Closed (NC), and Common terminals for versatile switching.

• Channels 7–12: Form-A (NO) contacts for simpler applications requiring a normally open switch.

• Number of Channels: 12 relay output channels.

• Relay Types:

• Solenoid Power: Integrated power distribution via either 125 VDC or 115 VAC bus to drive solenoid valves directly through the relay contacts.

2. Contact Ratings & Load Capacity
   The relays are engineered for industrial-grade switching, ensuring reliable operation in harsh environments:

• Resistive Load: Supports up to 5.0 A at 28 VDC or 120/240 VAC.

• Inductive Load: Supports up to 2.0 A at 28 VDC, with appropriate suppression for inductive loads.

• Minimum Load: The relays are designed to activate with a minimum load of 10 mA at 5 VDC, making them suitable for low-power control applications.

3. Hardware & Interface
   The board integrates with IS220PRLY I/O packs to enable relay control:

• I/O Pack Compatibility: Connects with the IS220PRLY I/O pack via a 37-pin D-type connector.

• Field Wiring: Equipped with two 24-point terminal blocks, either barrier-type or box-type, for secure and reliable field wiring.

• Isolation: Provides high-voltage galvanic isolation between the relay coils (control side) and the relay contacts (field side), ensuring safe operation in industrial environments.

Protection & Diagnostics

• Fusing: Each relay output channel is equipped with individual fuses to protect against short circuits in the solenoid power distribution, ensuring the failure of one device does not affect the entire board.

• Feedback Monitoring: The I/O pack continuously monitors the relay coil continuity and the drive circuit state to verify the relay has switched as expected.

• Surge Suppression: Varistors (MOVs) are built into the board to protect the relay contacts when switching inductive loads, preventing damage from voltage spikes.

• Board ID: An EEPROM on the board stores the board type, revision, and serial number, enabling automatic identification and configuration within the Mark VIe system.
