FUNCTIONAL DESCRIPTION:
IS200TRLYH2E is a Relay Output with Coil Sensing Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The Relay Output with TMR contact voting (TRLY) terminal board provides 12 contact-voted relay outputs. The board holds 12 sealed relays in each TMR section, for a total of 36 relays. The relay contacts from R, S, and T are combined to form a voted Form A (NO) contact. 24/125 V dc or 115 V ac can be applied.
TRLY does not have power distribution. For the Mark VI and VIe control systems, an optional power distribution board, IS200WPDF, can be added so that a standard 125 V dc or 115 V ac source, or an optional 24 V dc source with individual fuses, can be provided for field solenoid power. IS200WPDF provides a single fuse on the high side (pin 1 of J1–J4) of each power distribution circuit for ac applications where a fuse in neutral return wire (pin 3 of J1–J4) is not desirable. TRLYH2 is the same as TRLY1F except that the voted contacts form a Form B (NC) output. Both boards can be used in Class 1 Division 2 applications.
INSTALLATION:
Connect the wires for the 12 solenoids directly to two I/O terminal blocks on the terminal board as shown in the following figure, TRLY1F Terminal Board Wiring. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination strip attached to the chassis ground is located immediately to the left side of each terminal block. Solenoid power for outputs 1-12 is available if the WPDF daughterboard is used. Alternatively, customer power may be wired to the terminal block. The 28 V dc power for the terminal board relay coils and logic comes from the three I/O processors connected at JR1, JS1, and JT1.
OPERATION:
The 28 V dc power for the terminal board relay coils and logic comes from the three I/O processors connected at JR1, JS1, and JT1. The same relays are used for ac voltages and dc voltages, as specified in the Specifications section. TRLY1F and 2F use the same relays with differing circuits. Relay drivers are mounted on the TRLY1F and drive the relays at the frame rate. The relay outputs have a failsafe feature that votes to de-energize the corresponding relay when a cable is unplugged or communication with the associated I/O board or I/O pack is lost.
This board only supports TMR applications. The relay control signals are routed into TRLY1F from the three I/O processors R, S, and T through plugs JR1, JS1, and JT1. These signals directly control the corresponding relay driver for each TMR section R, S, and T. Power for each section’s relay coils comes in from its own I/O processor and is not shared with the other sections.
TRLY features TMR contact voting. The relay contacts from R, S, and T are combined to form a voted Form A (NO) contact. 24/125 V dc or 115 V ac can be applied. TRLY is the same except that the voted contacts form a Form B (NC) output. The following figure shows the TMR voting contact circuit.

What is a relay output with a coil-sensing terminal board?
A relay output with a coil sensing terminal board is a device that combines a relay for switching electrical loads with additional terminals to monitor the status or condition of the relay coil.
How does a coil-sensing terminal board work?
The coil sensing terminal board typically includes extra terminals that provide information about the relay coil's state. This can include detecting whether the coil is energized (activated) or de-energized (deactivated).
Where can I purchase a Relay Output Terminal Board?
You can purchase a Relay Output Terminal Board from World of Controls. WOC is a supplier of industrial automation and control products, including Relay Output Terminal Board.
