Functional Description

IS200TRLYH1FAA is a relay output terminal board developed by GE. It is a part of Mark VIe control system. The Relay Output with TMR contact voting terminal board is a specialized component designed to provide reliable and redundant relay outputs in a Triple Modular Redundant (TMR) configuration. The terminal board is equipped with 12 contact-voted relay outputs, resulting in a total of 36 relays when considering each TMR section. These relays are sealed, enhancing their durability and ensuring reliable performance in diverse operational conditions.

Features

• TMR Section Design: Within each TMR section, there are 12 sealed relays. This design offers redundancy and fault tolerance, allowing the system to maintain functionality even if one or more relays in a section were to encounter issues. The TMR architecture is particularly advantageous for critical applications where uninterrupted operation is paramount.
• Contact Voting and Configuration:The relay contacts from R, S, and T are intelligently combined to form a contact-voted Form A (Normally Open) contact. This voting mechanism enhances the reliability of the output, as the contact configuration is determined by a consensus among the redundant channels (R, S, and T).
• Voltage Compatibility: The board supports a versatile range of voltage options. It can accommodate either 24/125 V dc or 115 V ac, providing flexibility in adapting to different power sources based on system requirements.
• Arrangement Limitation: It's important to note that the terminal board does not support simplex arrangements. This limitation underscores its specialized design for TMR configurations, where redundancy and fault tolerance are prioritized.
• Power Distribution and Optional Power Distribution Board: It does not have built-in power distribution capabilities. However, users have the option to enhance the system by adding the power distribution board. This optional board enables the provision of a standard 125 V dc or 115 V ac power source. Additionally, it accommodates an optional 24 V dc source with individual fuses for field solenoid power. This feature enhances flexibility in powering the relay outputs based on specific application needs.

Installation Procedure

• Wire Connection for Solenoids:Begin the installation process by connecting the wires for the 12 solenoids directly to two I/O terminal blocks on the terminal board.
• Terminal Blocks Overview: Locate the two I/O terminal blocks on the board. Each block is securely held down with two screws and features 24 terminals designed to accept wires of up to 12 AWG. This setup ensures a robust connection for the solenoid wiring.
• Secure Wiring to Terminal Blocks: Carefully secure the wires for the solenoids to the designated terminals on the two I/O terminal blocks. Ensure proper placement and tight connection by utilizing the screws provided for each terminal.
• Shield Termination Strip: Take note of the shield termination strip attached to chassis ground, positioned immediately to the left side of each terminal block. Properly terminate the shield of the wiring to this strip, enhancing electrical safety and minimizing electromagnetic interference.
• Solenoid Power Availability: Solenoid power for outputs 1-12 can be sourced from the WPDF daughterboard if utilized. This daughterboard is designed to provide power distribution capabilities. Alternatively, if not using the WPDF daughterboard, power can be directly wired to the terminal block, offering flexibility in the power supply configuration.
• Optional WPDF Daughterboard:If opting for the WPDF daughterboard, follow the manufacturer's guidelines for installation. This daughterboard enhances the power distribution capabilities of the terminal board, simplifying the wiring process and providing an organized solution for solenoid power.
• Secure and Organize Wiring: After connecting the solenoid wires and, if applicable, attaching the shield termination, secure the wiring to ensure it is neatly organized. This helps prevent any accidental disconnections, reduces the risk of electrical faults, and facilitates future maintenance.
• Verify Connections: Before proceeding, double-check all connections to ensure they are properly seated and secure. C
• Power-Up Procedure: If applicable, follow the recommended power-up procedure outlined in the system documentation. This may involve gradually applying power to the solenoids while monitoring for any irregularities or faults.

Operation

• Power Source for Relay Coils and Logic: The terminal board operates with a 28 V dc power supply, providing the necessary energy for both the relay coils and logic components. This power is sourced from the three I/O processors connected at JR1, JS1, and JT1. The utilization of a common power source streamlines the system's power distribution and ensures consistent and reliable operation.
• Versatility in Voltage Usage: One notable feature is its ability to handle both ac (alternating current) and dc (direct current) voltages. This versatility is in accordance with the specifications outlined in the documentation. The same set of relays on the terminal board is efficiently employed for both ac and dc voltage applications, contributing to a unified and simplified design.
• Differentiated Circuits for H1F and H2F: It accommodates diverse applications by utilizing the same relays for H1F and H2F, which represent different circuits. This approach allows for flexibility in the configuration of relay circuits, ensuring compatibility with various system requirements. The differentiation in circuits enables the terminal board to address specific needs associated with H1F and H2F applications without compromising overall functionality.
• Integration with I/O Processors: The integration with the I/O processors is a crucial aspect of its operation. The connection points at JR1, JS1, and JT1 establish a communication link, allowing seamless coordination between the terminal board and the processors. This interconnected setup facilitates efficient relay control and logic processing in response to signals received from the connected processors.
• Reliability in Power Supply: The utilization of 28 V dc power ensures a stable and reliable supply for the relay coils and logic components on the terminal board. This voltage specification aligns with the requirements of the relays, contributing to the overall robustness and consistent performance in various operational scenarios.
• Compliance with Specifications: Adheres to the specifications outlined in the documentation. This commitment to specified voltage ranges and operational parameters ensures compatibility with the broader control system and enhances the reliability of the relay outputs in diverse environments.
