The IS200WPDFH1ACD is an Optional Power Distribution Daughterboard designed and manufactured by General Electric as a high-reliability component for the Mark VI Speedtronic Gas Turbine Control System. WPDFH1A is a daughterboard to TRLYH#F solenoids. WPDF holds two power distribution circuits, which can be independently used for standard 125 V dc, 115 V ac, or 24 V dc sources. Each section consists of 6 fused branches that provide power to the TRLYH#F terminal board. Each branch has its own voltage monitor across its fuse pair secondary. Each of these voltage detectors is fanned out to three independent open-collector drivers for feedback to each of the I/O processors R, S, T. The WPDF should not be used without TRLYH#F. Fused power flows through this board down to the TRLY terminal board points. Fuse power feedback is controlled by the TRLY.
POWER DISTRIBUTION CIRCUITS AND FUSING
The optional WPDFH1ACD power distribution board mounts on top of TRLY, making connections at J1 and J2. The board is held in place with one screw located at the center of the WPDF board. Power for the two sections of the board is wired in through three-pin connectors J1 and J4, and this can be daisy-chained out through adjacent plugs J2 and J3.
The WPDFH1ACD architecture hosts two independent power distribution circuits (PDCs). These sections can be energized concurrently or autonomously using standard industrial field power profiles, including 125 V DC, 115 V AC, or 24 V DC loops. Each PDC section splits its line into 6 branch segments, resulting in 12 total branches protected by industrial-grade fuses rated at 3.15 A. Fused excitation power safely flows through the daughterboard layers down into the integrated TRLY terminal board termination nodes.
INSTALLATION:
Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination strip attached to chassis ground is located immediately to the left side of each terminal block. Solenoid power for outputs 1-12 is available if the WPDF daughterboard is used. Alternatively, customer power may be wired to the terminal block.
Field wiring for the 12 system solenoids routes straight to the twin barrier-style I/O terminal strips (TB1 and TB2) situated on the base terminal board layout. Each block contains 24 high-torque screw connections capable of seating up to #12 AWG field conductors. Directly to the left of each terminal bank, an integrated, chassis-grounded shield termination strip is provided to suppress transient ambient noise. Solenoid loop power becomes active once the WPDF daughterboard receives supply power from the 3-pin J1 and J4 connectors, which can also be daisy-chained outward across neighboring J2 and J3 connection plugs.
POWER DISTRIBUTION BOARD:
The optional WPDF power distribution board mounts on top of TRLY, making connections at J1 and J2. The board is held in place with one screw located at the center of the WPDF board. Power for the two sections of the board is wired in through three-pin connectors J1 and J4, and this can be daisy-chained out through adjacent plugs J2 and J3.
OPERATION:
The same relays are used for the ac and dc voltage levels given in the Specification section. Also, the same relays are used on the H1F and H2F boards, but the circuit is different. Relay drivers are mounted on the relay terminal board and drive the relays at the frame rate. The relay outputs have failsafe features so that when a cable is unplugged or communication with the associated I/O board or I/O pack is lost, the inputs vote to de-energize the corresponding relays. This board only supports TMR applications. The relay control signals are routed into TRLY from the three I/O processors R, S, and T through plugs JR1, JS1, and JT1. These signals directly control the corresponding relay driver for each TMR section processor and is not shared with the other sections.

What is the IS200WPDFH1ACD?
The IS200WPDFH1ACD is an optional Power Distribution Daughterboard manufactured by General Electric (GE) for the Mark VI Speedtronic turbine control system. It provides fused power distribution for TRLY terminal board solenoid outputs.
What type of connections are used for field wiring?
The associated TRLY terminal board uses barrier-style terminal strips for field wiring. The terminal blocks provide screw connections capable of accepting conductors up to #12 AWG.
What is the purpose of the shield termination strip?
The shield termination strip is connected to chassis ground and is positioned beside the terminal blocks. It provides a termination point for field cable shields and helps control electrical noise and interference.
What happens to solenoid power when the WPDF daughterboard is installed?
When the WPDF daughterboard is supplied with the appropriate power, solenoid power for the associated outputs can be distributed through the fused WPDF branches to the TRLY terminal board.
How long does WOC typically take to evaluate or repair this board?
World of Controls lists a typical 3–7 business day repair/evaluation lead time, although actual turnaround can vary depending on the board's condition, failure mode, parts availability, and testing requirements.
