Functional Description
IS200TRLYH2EEB is a Solid-State Relay Output Board developed by GE. It is a part of the Mark VIe control system. Designed to provide high-reliability switching solutions with 12 output channels. Utilizing solid-state relays, this board ensures robust performance and longevity, suitable for demanding industrial applications. One of the features is its isolated output voltage feedback on all 12 circuits, enhancing monitoring capabilities and safety.
Features
- Solid-State Relays: Employs solid-state relays (SSRs) for its outputs. Unlike traditional mechanical relays, SSRs have no moving parts, which significantly increases their durability and lifespan. This design choice not only reduces maintenance needs with minimal wear and tear over time. The solid-state nature of these relays also contributes to improved performance in environments with high vibration or other challenging conditions.
- Certification for Hazardous Locations: One of the standout features is its certification for Class 1 Division 2 applications. This certification indicates that the board is suitable for use in environments where flammable gases, vapors, or liquids may be present but are not likely to be present under normal operating conditions. The use of solid-state relays is a key factor in achieving this certification, as they are inherently more reliable and less prone to sparking than mechanical relays.
Board Variants
- TRLYH1E for 115 V AC Applications: This variant is designed to handle 115 V AC, making it suitable for applications requiring this standard voltage level. It is ideal for interfacing with AC-powered equipment and systems.
- TRLYH2E for 24 V DC Applications: Tailored for 24 V DC applications, providing a reliable solution for low voltage DC systems. This makes it perfect for use in automotive, marine, and other DC-powered environments.
- TRLYH3E for 125 V DC Applications: It caters to high voltage DC applications, specifically 125 V DC. This variant is suitable for specialized industrial and utility applications where higher DC voltages are common.
Installation
- Wiring the Solenoids to the I/O Terminal Block: The relay board includes an I/O terminal block designed for connecting the customer's 12 solenoids. This terminal block is securely mounted on the terminal board and held in place by two screws, ensuring stability during operation. It features 24 terminals, allowing connections with wires up to 12 AWG, which provides robust and reliable connections for each solenoid. To begin the installation, identify the 12 solenoid wires that will be connected to the relay board. Each solenoid wire should be connected to the appropriate terminal on the I/O terminal block. Insert each wire into the corresponding terminal and tighten the screws to secure the connections, ensuring that each wire is firmly held to prevent any loose connections.
- Checking Polarity for DC Relays: For DC applications, the solid-state relays on the board are unidirectional, meaning they require correct polarity to function properly. When connecting the load to the DC relays, it is crucial to carefully observe and match the polarity of the wires to the relay terminals. Incorrect polarity can result in malfunction or damage to the relay board and connected devices. Ensure that each DC solenoid wire is connected with the correct polarity to prevent any issues during operation.
- Grounding the System: Proper grounding is essential for the safe and reliable operation of the relay board. A shield terminal strip attached to the chassis ground is provided immediately to the left of each terminal block. This strip ensures that the system is grounded correctly, which helps to reduce electrical noise and improve overall safety. To ground the system, identify the shield terminal strip and connect a grounding wire from the strip to the chassis ground. This connection is critical for reducing electrical interference and enhancing the safety of the installation.
- Securing the Terminal Block: Ensuring that the terminal block is securely fastened is crucial for maintaining stable connections and preventing any accidental disconnections. Verify that the I/O terminal block is firmly held down by its two screws. Tighten the screws if necessary to ensure the block does not move during operation. After all solenoid wires are connected and secured, inspect each connection to ensure there are no loose wires or potential shorts. This step is important to prevent any issues during the operation of the relay board.
- Final Checks and Power-Up: Before powering up the relay board, perform a thorough inspection of all connections and ensure that the installation complies with the necessary electrical standards and safety protocols. Double-check that all solenoid wires are correctly connected and secured in the I/O terminal block, and that the polarity for DC relays is correctly observed. Confirm that the grounding wire is properly connected to the chassis ground through the shield terminal strip. Once all connections are verified, power up the relay board and test each relay output to confirm proper operation. Ensure that each connected solenoid activates as expected and utilize the isolated output voltage feedback feature to monitor each circuit and detect any issues with the solenoids or connections.
