IS230TRLYH1BA is a Relay Output Board developed by GE. It is a part of the Mark VIe control system. It is engineered to support reliable relay-based output functions in complex industrial environments, including power generation and process automation. With flexible configurations and robust electrical design, the board is ideal for managing control signals, solenoids, and specialized field devices.
1. Outputs 1–6: Configurable Relay Circuits
The first six relays on the TRLYH1B board are designed for versatility. They can be configured through jumpers either as dry Form-C contact outputs or as drivers for external solenoids. This dual capability allows the board to support a wide variety of field applications, from standard control logic to valve actuation.
For solenoid applications, the board can use 125 V DC, 115/230 V AC, or an optional 24 V DC power source. Each channel features individually selectable fuses and on-board suppression circuitry, ensuring safe operation, noise filtering, and protection of connected field devices.
2. Outputs 7–11: Unpowered Isolated Contacts
Relays 7 through 11 provide unpowered, isolated Form-C contact outputs. These are ideal for control and signaling functions that require electrical isolation but do not depend on onboard solenoid power. Their isolated design enhances safety and prevents interference between channels.
3. Output 12: Special Purpose Relay
Output 12 is an isolated Form-C contact, specifically reserved for special applications such as ignition transformers or other devices requiring a dedicated, isolated switching path. Its design ensures dependable operation even in demanding industrial conditions.
1. Terminal Blocks
All 12 relay outputs are wired directly to two I/O terminal blocks attached to the terminal board. Each block is secured with two screws and equipped with 24 terminals, supporting up to #12 AWG wires. This design provides strong, reliable connections suitable for heavy-duty industrial wiring.
2. Shielding and Grounding
A shield terminal strip, connected to chassis ground, is positioned on the left side of each terminal block. This feature supports proper cable shielding, helping to reduce electrical noise and maintain signal integrity throughout the system.
3. Solenoid Power Connections
Solenoid power for outputs 1–6 is typically supplied through the JF1 connector. If multiple TRLY boards are installed, JF2 can be used to daisy-chain power between boards. In cases where external power is preferred, customers can wire their own power supply directly to TB3. Additionally, JG1 provides a dedicated connection for powering the special solenoid associated with Output 12.

The board contains 12 plug-in magnetic relays. Outputs 1-6 are configurable, outputs 7-11 are isolated Form-C contacts, and output 12 is dedicated to special applications.
What configurations are available for outputs 1-6?
Outputs 1-6 can be jumper-configured either as dry Form-C contact outputs or as drivers for external solenoids. They support multiple power sources and include onboard protection.
What power options are available for solenoid operation?
The board supports 125 V DC, 115/230 V AC, and optional 24 V DC solenoid power sources. Each channel includes selectable fuses and suppression circuitry.
Are outputs 7-11 powered?
No. Outputs 7-11 are unpowered isolated Form-C contacts, used mainly for signaling or isolated switching functions.
What is the purpose of the 12th relay?
Output 12 is an isolated Form-C relay designed for special applications, such as powering an ignition transformer or unique field devices requiring isolated switching.
How are the relays wired to the control system?
All 12 outputs connect through two I/O terminal blocks mounted on the terminal board. Each block contains 24 terminals and supports wiring up to 12 AWG.
How is solenoid power supplied to the board?
Solenoid power for outputs 1–6 is typically connected through JF1. JF2 allows daisy-chaining power to other TRLY boards. External power can also be connected directly to TB3, and JG1 supplies power for the Output 12 solenoid.
