DFH1ACC is an optional power distribution board developed by GE. It is a part of Mark VIe control system. WPDFH1A is a specialized daughterboard designed to be used with the TRLY terminal board to provide power distribution for the customer's solenoids. The board contains two independent power distribution circuits. These circuits can handle different standard power sources 125 V DC, 115 V AC, or 24 V DC. Each power distribution circuit has six fused branches.
Features
- Power Distribution: Distributes power from various standard sources across two independent circuits. It is designed to handle 125 V DC, 115 V AC, or 24 V DC, providing flexibility in different industrial applications. Each circuit features six fused branches that offer independent protection to ensure system reliability and prevent overcurrent issues.
- Voltage Monitoring and Feedback: Each fused branch is monitored via voltage detectors installed across the secondary fuse pair. These detectors are connected to three open-collector drivers that provide feedback to three I/O processors (R, S, and T). This feedback allows the control system to monitor the operational status of each power branch and detect faults or irregularities, improving system diagnostics and maintenance.
- Mounting and Connections: The board is mounted on the TRLY terminal board using a single screw at the center to ensure stability. Power connections are made through three-pin connectors (J1 and J4), which facilitate integration into the system. Power input can be daisy-chained through adjacent plugs (J2 and J3) to allow for scalability and distribution to additional boards or components.
- Operational Dependency: It is designed for use with the terminal board. Fused power is distributed through the WPDFH1A, with power flowing to the terminal board points. The board manages fuse power feedback and ensures consistent power flow to connected solenoids and other components.
Voltage Monitoring and Feedback
- Each branch of the power distribution board is equipped with a voltage monitor across its secondary fuse pair. These voltage monitors ensure real-time tracking of the voltage status on each branch. The monitoring system is connected to three independent open-collector drivers, which relay the voltage information to the system's control processors. The feedback from these drivers is provided to three I/O processors labeled R, S, and T.
- This feedback mechanism enables the system to continuously monitor the operational status of each fused branch, allowing for detection of any voltage irregularities or blown fuses. This contributes to improved diagnostics, helping maintain operational reliability by identifying faults in the power distribution system promptly.
Operational Dependency
- The power distribution board is specifically designed for exclusive use with the TRLYH#F terminal board. It operates as a daughterboard within the Mark VIe control system, where fused power is distributed. The power flows from the board down to the connection points on the TRLY terminal board, ensuring that solenoids and other components receive controlled power.
- The board manages the fuse power feedback, ensuring that any issues related to power distribution—such as blown fuses or irregularities—are reported back to the system's I/O processors. This setup is essential for maintaining reliable and efficient power distribution in the overall control system.
Mounting and Connections
- The board is designed for secure attachment onto the TRLY terminal board, with its mounting system ensuring a stable and reliable connection. Connections are facilitated through connectors J1 and J2, which are specifically positioned to allow easy access and integration with other components.
- The board is secured in place with a central screw, providing additional stability during operation.
Power Wiring
- Power is supplied to the board through two main sections, with inputs connected via three-pin connectors J1 and J4.
- These connectors simplify the process of integrating external power sources, making it easy to connect and manage power flow to the board. This streamlined power wiring design supports efficient power management for the system.
Daisy Chaining
- To support scalability and expandability, the WPDF board features daisy-chaining capabilities. The power input can be distributed to additional boards or components through connectors J2 and J3.
- This daisy-chaining functionality allows for a modular power distribution system, enabling the connection of multiple boards in a series, ensuring that additional components can be powered seamlessly.
- This feature makes the system highly adaptable for larger installations or expansions.
