Functional Description

IS200TRLYH2F is a relay output terminal board developed by GE. It is a part of Mark VIe control system. The Relay Output Terminal Board with TMR Contact Voting has 12 contact-voted relay outputs. Each TMR section on the board has 12 sealed relays, for a total of 36 relays. The design of the relay outputs is such that the R, S, and T relay contacts are combined to form a voted Form B (Normally Closed) contact configuration. This voting mechanism ensures redundancy and reliability in critical applications by having multiple relay contacts working together to form a single reliable output. The board is versatile in terms of power supply options. It can be used with either a 24/125 V DC (direct current) power source or a 115 V AC (alternating current) power source, depending on the specific requirements of the control system and the application.

Features

• The board has no power distribution. An optional power distribution board, WPDFH1A, can be added to the Mark VI and VIe control systems to provide a standard 125 V dc or 115 V ac source, or an optional 24 V dc source with individual fuses, for field solenoid power.
• For ac applications where a fuse in the neutral return wire (pin 3 of J1-J4) is not desirable, WPDFH2A provides a single fuse in the high side (pin 1 of J1-J4) of each power distribution circuit.
• TRLY1F is only compatible with TMR applications and works with the PDOA / YDOA I/O pack. Three TMR I/O packs connect to the terminal board's 37-pin D-type connectors JR1, JS1, and JT1.

Installation

• Before installing the terminal board, ensure that the power to the control system is turned off to prevent any electrical hazards. Place the board in the desired location, providing enough space for easy access to the I/O terminal blocks and connections.
• The terminal board features two I/O terminal blocks, each equipped with 24 terminals that can accept wires up to 12 AWG (American Wire Gauge). Connect the wires from the 12 solenoids directly to these terminal blocks. Carefully insert the wires into the appropriate terminals, and secure them by tightening the screws to ensure a reliable connection.
• Each terminal block comes with a shield termination strip connected to the chassis ground on the left side. This grounding connection helps protect the terminal board and connected equipment from electromagnetic interference (EMI). Ensure that the shield termination strips are securely connected to the chassis ground to establish a proper ground connection.
• If the control system includes a WPDF (Waveform and Protocol Development Facility) daughterboard, solenoid power becomes available for outputs 1 to 12. This additional daughterboard may be necessary depending on the specific system configuration and requirements.
• Depending on the application's power requirements, customer power can also be wired to the terminal block. If there is a need for additional power supply for specific components or devices connected to the terminal board, follow the manufacturer's guidelines and specifications for customer power wiring.
• The terminal board requires a 28 V DC power supply to energize the relay coils and provide power for the logic circuits. This power is typically provided by three I/O processors connected at JR1, JS1, and JT1. Ensure that these I/O processors are properly connected and powered to supply the necessary voltage to the terminal board.
• Once all the connections are made, double-check all the wiring to ensure correctness and security. Before applying power to the control system, perform a thorough inspection to verify that everything is in place and there are no loose connections or exposed wires. After confirming the integrity of the installation, apply power to the control system and conduct thorough testing to validate the functionality of the relay output terminal board.

Operation

• The terminal board requires a 28 V DC power supply to operate the relay coils and logic circuits. This power is supplied by the three I/O processors connected at JR1, JS1, and JT1. These processors are responsible for providing the necessary voltage and current to energize the relays and enable the logic operations on the terminal board.
• Designed to work with both alternating current (AC) and direct current (DC) voltages. This dual voltage compatibility allows for greater flexibility in various applications, accommodating different power supply configurations as needed.
• It shares relays to optimize space and resources. While multiple circuits utilize the same set of relays, they are connected to different logic and control circuits. This design allows for efficient utilization of the relay resources while maintaining separation and integrity among the different control circuits.
• Equipped with relay drivers that control the operation of the relays at the desired frame rate. The relay drivers ensure precise and synchronized relay switching based on the input signals received from the control system.
• The relay outputs on the terminal board are equipped with a failsafe feature. This feature is crucial for safety and reliability in critical applications. In the event of a cable disconnection or loss of communication with the associated I/O board or I/O pack, the relay outputs implement a voting mechanism. The voting system works to de-energize the corresponding relay, ensuring that the relay defaults to a safe state and prevents unintended actions in case of communication failure or signal loss.

Characteristics

• Provides a total of 12 output relay channels, offering ample capacity to control and manage multiple electrical circuits or devices simultaneously.
• 17.8 cm in width and 33.02 cm in height. This relatively small footprint makes it suitable for installations with limited space constraints.
• Designed to operate effectively within a wide temperature range, from as low as -30 degrees Celsius to as high as 65 degrees Celsius. This versatility ensures its performance in both extreme cold and hot environments.
• Technology - surface-mount technology (SMT)
• 12 fused solenoid driver relays providing protection and controlled power delivery to connected solenoid devices. This feature enhances safety and longevity.
• In addition to solenoid driver relays, it also offers 12 dry circuit relays. These relays are ideal for applications where you need to switch low-voltage or signal-level circuits without any voltage applied to the contacts when they are in the open state.
• The relays used in this device are of the mechanical type, known for their robustness and durability, making them suitable for a wide range of industrial and commercial applications.
• Designed to be controlled using TMR technology exclusively. This control method allows for precise and efficient management of the relay channels.
• Does not feature relay suppression, which means it doesn't include additional circuitry for noise or interference reduction. This may be important to consider in applications with sensitive electronics.
• With 12 solenoid fuse sense capabilities, the device can monitor the status of the fuses associated with the solenoid driver relays, providing real-time feedback on their operational status.
• Supports a versatile range of operating voltages, with an AC voltage rating of 120V and DC voltage ratings of 28V and 125V. This flexibility ensures compatibility with various power sources.
• Internal Switching Power Supply, it does not incorporate an internal switching power supply. Users may need to provide external power supplies as necessary.
• The terminal type used in this device is a barrier-type terminal, which facilitates secure and organized wiring connections, contributing to ease of installation and maintenance.
