WESTINGHOUSE 5X00059G01 | WDPF Digital Output Module – 32 Point

Description Product Introduction The WESTINGHOUSE 5X00059G01 is a digital output module from the WDPF (Westinghouse Distributed Processing Family) system—the DCS platform that ran power plants, chemical facilities, and industrial boiler houses through the 1980s and 1990s. This module lives in the I/O racks, typically paired with a termination panel that routes the 32 outputs to field devices like solenoids, motor starters, and indicating lights. What makes the WESTINGHOUSE 5X00059G01 notable is the output protection. Each channel has its own short-circuit and thermal protection. If an output sees a dead short, the module shuts that channel down but keeps the other 31 running. The “G01” suffix indicates the final hardware revision with improved transient suppression. Earlier versions (5X00059 without the G01) had a tendency to fail open on inductive loads. The G01 revision handles the back-EMF from solenoid coils better. Key Technical Specifications Parameter Specification Model WESTINGHOUSE 5X00059G01 Series WDPF (Westinghouse Distributed Processing Family) Module Type Digital Output Channels 32 (sourcing or sinking, depending on termination) Output Voltage 24 VDC (nominal, 18–30 VDC range) Output Current 0.5 A per channel, continuous Total Current 10 A maximum per module Protection Short-circuit, over-temperature, over-voltage Response Time < 2 ms (typical) Isolation 1500 VAC between outputs and logic Status Indication Per-channel LED (green when on), module OK LED Backplane Interface WDPF I/O rack (DPU backplane) Operating Temp 0°C to 60°C Power Consumption 3 W (logic) field supply Termination Via WDPF termination panel (5X00059T or equivalent) Firmware / Software Versions & Upgrade Notes The WESTINGHOUSE 5X00059G01 contains no user-upgradable firmware. The module is hardware-based—no onboard processor, no flash memory. All control comes from the WDPF DPU (Distributed Processing Unit) that hosts the module. DPU compatibility: Works with WDPF DPU models I, II, and III. Compatible with Emerson Ovation migration systems when used with legacy I/O racks. Software configuration: Configured in the WDPF database tool (WDPF Configuration Editor or Ovation Engineering Workstation). The module’s address is set by its slot position in the rack—no dip switches on the module itself. Revision upgrade path: 5X00059 (original) → 5X00059G01. The G01 revision is the final production version with improved transient protection. It is backward-compatible with all earlier versions. ⚠️ Field note: The WESTINGHOUSE 5X00059G01 has a specific field power sequencing requirement. Apply field power after the rack power stabilizes. If you power the field 24 VDC before the logic power, the outputs can pulse ON for a few milliseconds during boot. In a steam turbine control application, that’s a problem. Sequence your power supplies accordingly. Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes WESTINGHOUSE 5X00059 (original) WESTINGHOUSE 5X00059G01 Drop-in Same termination panel, same backplane. The G01 revision adds transient protection. No wiring changes. WESTINGHOUSE 5X00059G01 (same) WESTINGHOUSE 5X00059G01 Drop-in Direct replacement. Any G01 revision is interchangeable. WESTINGHOUSE 5X00060 (different I/O type) WESTINGHOUSE 5X00059G01 Incompatible 5X00060 is an input module. Termination panels are not interchangeable. Emerson KJ3002X1-BC1 (Ovation digital output) WESTINGHOUSE 5X00059G01 Incompatible Different rack system. Ovation I/O uses a different backplane and termination. You cannot mix WDPF and Ovation I/O in the same rack. Third-party digital output WESTINGHOUSE 5X00059G01 Incompatible No direct substitute. WDPF I/O is proprietary. Frequently Asked Questions Q: What termination panel does this module use? The WESTINGHOUSE 5X00059G01 typically mates with the 5X00059T termination panel. This panel provides screw terminals for 32 field devices and houses the field power distribution fuses. Some installations use a custom termination assembly—check your existing setup. Q: Can I use this module with 120 VAC loads? No. The WESTINGHOUSE 5X00059G01 is a 24 VDC output module. For 120 VAC loads, you need an interposing relay. The module can drive a small relay (0.5 A coil), which then switches the AC load. Do not connect AC directly to the outputs—it will destroy the output transistors. Q: How do I test an output channel? Use the WDPF diagnostic tools or Ovation Engineering Workstation. Force the output ON from the DPU. The green LED on the WESTINGHOUSE 5X00059G01 for that channel should light. If it does, the module is responding. Check voltage at the termination panel—if the LED is on but no voltage at the terminal, the output driver has failed. Q: My outputs are stuck ON even with the module removed. Bad module? No—if the module is removed, the outputs are physically disconnected from the backplane. If field devices are still energized with the module out, the problem is in the termination panel or the field wiring. The WESTINGHOUSE 5X00059G01 cannot pass power when it’s not inserted. Q: Does this module support hot swap? No. WDPF I/O racks do not support hot swapping. Power down the rack before removing or inserting the WESTINGHOUSE 5X00059G01. The backplane connectors are not designed for live insertion. Q: What’s the difference between 5X00059G01 and 5X00059G02? There is no G02 revision in the standard catalog. Some custom OEM variants may carry a G02 suffix, but the production version ended with G01. If you see a G02, verify it against the original equipment documentation before assuming compatibility. Q: My module shows a red “FAULT” LED. What do I do? A red FAULT LED on the WESTINGHOUSE 5X00059G01 usually indicates a short circuit on one or more outputs. The module will shut down the affected channels but keep running. Check field wiring for shorts. If the fault persists after clearing the wiring issue, cycle power to the rack. If the LED stays red, the module has internal damage—replace it. A03B-0808-C201 CPU 3HAC025784-001 PM856K01 PLC IC2800Y102A2 PLC TOSHIBAPU224/TPU224S .
