FUNCTIONAL DESCRIPTION:
IS230TRLYH3E is a Solid-State Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The TRLYH3E terminal board is equipped with 12 solid-state relay outputs, each featuring isolated output voltage feedback. These relays enable the board to meet certification standards for Class 1 Division 2 applications. Unlike mechanical relay boards which offer form-C contacts, all 12 outputs on the TRLYH3E consist of single normally open (NO) contacts. The board does not include user solenoid power distribution. Within the Mark VIe system, the TRLYH1E collaborates with the PDOA I/O pack, supporting both simplex and TMR applications. The PDOA unit plugs into the DC-37 pin connectors located on the terminal board. For simplex systems, connector JA1 is utilized, while connectors JR1, JS1, and JT1 are employed for TMR systems.
INSTALLATION:
Connect the wires from the 12 solenoids directly to the I/O terminal block on the TRLYH3E Terminal Board, as illustrated in the provided figure. Secure the terminal block in place using two screws; it features 24 terminals capable of accepting wires up to #12 AWG. Since the DC relays are unidirectional, polarity awareness is essential when linking loads to these relays. Adjacent to each terminal block, there is a shield terminal strip connected to the chassis ground. Remember, it is the customer's responsibility to externally power the solenoids.
OPERATION:
The TRLYH3E does not include any solid-state relays, relay drivers, or output monitoring components. Upon power-up, the relays remain de-energized regardless of any connected control. A failsafe feature is integrated into the relay outputs, causing the corresponding relay to de-energize in the event of a cable disconnection or loss of communication with the associated I/O processor.
For simplex operation, control signals and relay output voltage feedback signals are exchanged between the I/O processor and TRLY via connector JA1. In TMR applications, relay control signals are distributed to TRLY from the three I/O processors R, S, and T through connectors JR1, JS1, and JT1. These signals undergo a voting process, and the resultant signal controls the corresponding relay driver. Power for the relay drivers is supplied from all three I/O processors and is shared through diodes. The figure below depicts the TRLYH1E within a TMR system.

What is the purpose of the solid-state Relay Output terminal board?
The terminal board is designed to provide 12-output relay functionality using solid-state relays. It offers isolated output voltage feedback on all 12 circuits, allowing for precise monitoring and control of the relay outputs.
What is the significance of isolated output voltage feedback on all 12 circuits?
The isolated output voltage feedback means that each of the 12 relay circuits has its dedicated feedback mechanism. This allows for independent monitoring and feedback of the relay outputs. Isolation ensures that signals from one circuit do not interfere with or affect the performance of other circuits, ensuring accurate and reliable feedback information.
What does it mean to be certified for Class 1 Division 2 applications?
The Class 1 Division 2 certification indicates that the board meets the safety requirements for operating in hazardous environments where flammable gases, vapors, or liquids may be present under abnormal conditions.
