Functional Description
IS200TRLYH1DAC is a Relay Output Terminal Board developed by GE. It is a part of the Mark VIe control system. The module is equipped with six plug-in magnetic relays. Each of these relays operates with Form-C contact outputs, which means they have a common terminal (COM), a normally open terminal (NO), and a normally closed terminal (NC). This configuration allows for versatile control schemes, including switching between two circuits or isolating a load.
Features
- Relay Configuration: Common (COM), Normally Open (NO), and Normally Closed (NC). Easy to replace or upgrade, ensuring maintenance is straightforward.
- Power and Fusing: The board can operate with standard 24 V DC or 125 V DC power sources, providing flexibility in integration with existing systems. Each relay circuit is fused, which protects both the relay and the connected load (such as external solenoids) from overcurrent conditions, enhancing safety and reliability.
- Feedback Mechanism: Includes a feedback system on each relay circuit to monitor the status of external solenoids. Feedback sensing is done between the NO (Normally Open) output terminal and the SOL (Solenoid) output terminal. This setup allows the detection of issues such as a disconnected or faulty solenoid.
- Relay Operation: When a relay is energized, the NO contact closes, allowing current to flow from the COM terminal to the NO terminal. When de-energized, the NC contact remains closed, allowing current to flow from the COM terminal to the NC terminal. This dual-state capability enables the module to control circuits or isolate them as needed.
- Power Supply: The board supports both 24 V DC and 125 V DC power sources, making it suitable for a range of applications. Fuses on each relay circuit prevent damage due to excessive current, ensuring long-term durability and protection.
- Feedback for Solenoid: Each relay circuit includes a sensing mechanism that monitors the condition of the external solenoids. By checking the circuit between the NO output terminal and the SOL output terminal, the board can detect when a solenoid is not functioning correctly (e.g., if it has an open circuit or if it fails to actuate). This feedback mechanism is crucial for maintenance and troubleshooting, as it provides an immediate indication of solenoid issues, allowing for prompt corrective action.
Installation
- TB1 Terminal Block: The TB1 terminal block is crucial for connecting the six relay outputs of the TRLYH1D module. This block, mounted securely on the terminal board, is held in place by two screws, ensuring it remains firmly in position. It features 24 terminals capable of accepting wires up to 12 AWG, allowing for robust and reliable connections. During installation, the customer's six relay output wires must be correctly identified and connected to the appropriate terminals on the TB1 block, with screws tightened to prevent any loose connections.
- Shield Terminal Strip: Adjacent to the TB1 terminal block, the shield terminal strip plays a vital role in grounding. This strip is attached to the chassis ground, which is essential for reducing electrical noise and enhancing the overall safety of the installation. Proper grounding through this shield terminal strip helps to ensure that any electrical interference is minimized, which is particularly important in industrial and automation environments where reliable operation is critical.
- JF1 and JF2 Connectors: The JF1 and JF2 connectors facilitate the power supply to the relay outputs. The JF1 connector is used to plug in the solenoid power for outputs 1-6, serving as the standard method for powering these outputs. For setups that require multiple TRLY relay boards, the JF2 connector can be utilized to daisy-chain power, allowing for seamless expansion. This configuration ensures that power can be efficiently distributed across multiple boards, provided the power source can support the combined load.
- TB3 Terminal Block:For installations where the standard power connectors (JF1 and JF2) are not used, the TB3 terminal block offers an alternative for direct customer power wiring. This flexibility is particularly useful when dealing with custom or external power sources. By connecting the power source directly to TB3, installers can ensure that the TRLYH1D board receives the appropriate voltage (either 24 V DC or 125 V DC) necessary for operation. This option provides additional versatility in various installation scenarios.
- Mounting and Grounding: Ensuring the terminal board is securely mounted in an appropriate enclosure or on a panel is the first step in the installation process. The chosen location should be suitable for electrical installations, taking into account factors such as moisture, dust, and temperature. Grounding is a critical step, achieved by connecting a grounding wire from the shield terminal strip to the chassis ground. This not only enhances safety but also reduces electrical noise, contributing to the reliable operation of the system.
- Power Up and Testing: After all connections are verified and secured, the system can be powered up. It is essential to test each relay output to ensure proper operation and to confirm that each external solenoid functions as expected. The feedback mechanism integrated into the TRLYH1D module allows for the detection of issues with the external solenoids, facilitating prompt troubleshooting and maintenance. This final step ensures that the installation is not only complete but also fully operational and ready for use in its intended application.
