FUNCTIONAL DESCRIPTION:

IS200TRLYH1FAA is a Relay Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The Relay Output with TMR Contact Voting (TRLY1F) terminal board provides 12 contact-voted relay outputs. Each of the three TMR segments on the board contains 12 sealed relays, totaling 36 relays. A voted Form A (normally open, NO) contact is achieved by combining the relay contacts from the R, S, and T segments. The board supports 115 V AC or 24/125 V DC power. However, TRLY1F does not include electricity distribution. An optional power distribution board can be added to the Mark VI and VIe control systems to supply field solenoid power using either a conventional 125 V DC or 115 V AC source, an optional 24 V DC source with individual fuses, or both. For AC configurations where a fuse in the neutral return wire (pin 3 of J1-J4) is undesirable, the board provides a single fuse on the high side (pin 1 of J1-J4) of each distribution circuit. The main distinction between the TRLY2F and TRLY1F boards is that the TRLY2F produces voted contacts with a Form B (normally closed, NC) output. Both boards are suitable for Class 1 Division 2 applications.

INSTALLATION:

The 12 solenoid wires are directly connected to two I/O terminal blocks on the terminal board. Each block features 24 terminals that support wire sizes up to #12 AWG and are secured by two screws. A shield termination strip is included with each block, connected to the chassis ground just to the left. If the WPDF daughterboard is installed, solenoid power for outputs 1 through 12 is supplied. Alternatively, customer power can be connected to the terminal block. The three I/O processors at JR1, JS1, and JT1 provide 28 V DC power for the relay coils and logic on the terminal board.

OPERATION:

• The three I/O processors connected at JR1, JS1, and JT1 supply 28 V DC power for the terminal board's relay coils and logic. As noted in the specifications, the same relays are used for both AC and DC voltages. While TRLY1F and TRLY2F use identical relays, their circuits differ. TRLY1F features relay drivers that operate at the frame rate.

• The relay outputs include a failsafe mechanism that automatically de-energizes the corresponding relay if a cable is unplugged or communication with the connected I/O board or I/O pack fails.

• TRLY1F is designed specifically for TMR applications, with JR1, JS1, and JT1 routing relay control signals from the R, S, and T I/O processors to the appropriate relay driver. Each section—R, S, and T—has its relay coil power, ensuring power is not shared between sections.

• TRLY1F employs TMR contact voting, combining the relay contacts from R, S, and T to form a voted Form A (normally open, NO) contact. It supports 115 V AC or 24/125 V DC. The key distinction between TRLY1F and TRLY2F is that TRLY2F produces a voted Form B (normally closed, NC) output.

FREQUENTLY ASKED QUESTIONS:

How does TMR contact voting work in TRLY1F?

TRLY1F combines relay contacts from three sections—R, S, and T—to create a voted Form A (normally open) contact. Each section is independently powered by its own I/O processor.

What happens if communication with the I/O board fails?

The relay outputs have a failsafe mechanism that de-energizes the corresponding relay in the event of a cable disconnection or communication failure with the I/O board or pack.

Are TRLY1F and TRLY2F relays different?

No, TRLY1F and TRLY2F use the same relays. However, TRLY2F produces a voted Form B (normally closed) output, while TRLY1F produces a voted Form A (normally open) output.
