Product Description

Product Overview

The GE IS200TRLYH1B is a Relay Output Terminal Board designed for the GE Mark VI turbine control system. It provides relay-based switching interfaces between the control system and external field devices.

The board contains 12 plug-in electromechanical relays. These relays are used to control external equipment such as solenoid valves, alarms, ignition-related circuits, and other industrial devices. The board also provides relay coil feedback monitoring, fused power distribution, and transient suppression.

The IS200TRLYH1B supports simplex and Triple Modular Redundant (TMR) configurations, depending on the associated I/O hardware and system design.

Typical Applications

Gas Turbine Control Controls solenoid valves, auxiliary equipment, and other discrete output devices in gas turbine systems.
Steam Turbine Control Provides relay switching for auxiliary systems, alarms, and selected operating sequences.
Power Generation Interfaces control-system outputs with external relays, circuit-control devices, and equipment status circuits.
Ignition Systems The special-purpose relay circuit can be used for designated ignition-related applications when configured according to GE documentation.
Industrial Process Automation Supports relay-based control of external devices, interlocks, and alarm circuits.

Frequently Asked Questions

Q1: What is the GE IS200TRLYH1B?

The IS200TRLYH1B is a GE Mark VI Relay Output Terminal Board used to interface control-system commands with external relay-operated devices.

Q2: How many relay channels does the IS200TRLYH1B have?

It contains 12 plug-in relay channels.

Q3: What type of relay contacts does it use?

The board uses Form C (SPDT) relay contacts, providing normally open and normally closed switching options.

Q4: What are the relay output ratings?

Documented ratings include 3 A at 24 VDC, 0.6 A at 125 VDC, and 3 A at 120/240 VAC for the applicable relay circuits. The special-purpose relay has a separate rating.

Q5: Can the IS200TRLYH1B control solenoid valves?

Yes. The first six relay circuits can be configured for powered solenoid operation when the appropriate field power and fuse arrangements are used.

Q6: Does the board support TMR operation?

Yes. It supports TMR arrangements when paired with the appropriate GE I/O hardware and system configuration.

Q7: What is the purpose of relay coil feedback?

Coil feedback allows the control system to compare the commanded relay state with the actual relay-drive condition and identify possible faults.
