The WPDFH1A is a crucial component for powering the relays on the TRLY terminal board. Here’s a breakdown of its primary functions:

  • Power Distribution: The board has two independent power distribution circuits, which can be configured for 125 VDC, 115 VAC, or 24 VDC. It routes this power to the TRLYH1F terminal board, which in turn powers solenoids and other field devices.
  • Fused Branches: Each of the two circuits is made up of six fused branches, for a total of twelve branches. This individual fusing provides protection for each circuit, preventing a short circuit in one device from affecting the entire system.
  • Voltage Monitoring: The board includes voltage monitors across each fuse pair. If a fuse blows, the board detects the loss of voltage and provides feedback to the main Mark VI I/O processors (R, S, and T) through open-collector drivers. This diagnostic feedback is essential for troubleshooting and for alerting the operator to a fault.
  • Daughter Board Design: The IS200WPDFH1A is designed to be a daughter board that plugs directly into the TRLYH1F terminal board. This modular design simplifies installation and maintenance, as the two boards are often treated as a single, replaceable unit.
