Westinghouse 5X00106G02 – 8-Channel Analog Input Module | WDPF Distributed Control System
Engineering Background: The Westinghouse WDPF (Westinghouse Distributed Processing Family) platform was engineered for mission-critical process control in power generation, petrochemical, and heavy industrial environments. Introduced in the 1980s and continuously refined through the 1990s, WDPF remains operational in hundreds of baseload power plants and refinery control rooms worldwide due to its deterministic scan cycle, robust I/O architecture, and proven field reliability.
Product Positioning: The 5X00106G02 is an 8-channel analog input module designed for the WDPF DCS I/O subsystem. It conditions and digitizes field-level analog signals—current loops, voltage references, and thermocouple/RTD inputs—and delivers engineering-unit values to the WDPF controller over the proprietary WEStation data highway. This module is the preferred replacement for aging 5X00106G01 units and is fully backward-compatible within the WDPF rack infrastructure.

- Deterministic Scan: Synchronized to WDPF controller scan cycle, ensuring consistent latency for closed-loop PID control
- Multi-Signal Flexibility: Single module supports mA, voltage, TC, and RTD inputs—reducing spare-parts inventory complexity
- Proven MTBF: Field data from power plant installations demonstrates >100,000-hour MTBF under continuous operation
System Architecture & Signal Flow
Field transmitters connect to the WDPF termination panel via shielded twisted-pair cables. The 5X00106G02 module plugs into the WDPF I/O rack backplane, where it receives +5 V power and communicates over the proprietary WEStation serial data highway. The module’s on-board A/D converter samples each channel sequentially, applies linearization (for TC/RTD inputs), performs cold-junction compensation, and places the engineering-unit result in the WDPF data table for the controller to read on each scan. Diagnostic status bits (open-circuit, over-range, under-range) are reported back to the WDPF operator console in real time.

Technical FAQ
Q: Is the 5X00106G02 compatible with the WDPF II controller?
A: Yes. The module is compatible with both original WDPF and WDPF II controller generations, provided the rack backplane is a standard WDPF I/O chassis.
Q: Can this module be used with Ovation DCS after migration?
A: No. Ovation uses a different I/O bus architecture. The 5X00106G02 is specific to the WDPF platform. Ovation equivalents are separate part numbers.
Q: What is the difference between G01 and G02 revisions?
A: The G02 revision incorporates an improved A/D converter with enhanced noise immunity and extended thermocouple type support (added R, S, B types). It is a direct functional superset of G01.
Q: Do you provide a test report?
A: Yes. A functional test report is available upon request for each unit prior to shipment.
Q: Can I return the module if it does not work in my system?
A: Yes. We offer a 90-day DOA warranty with exchange or full refund, subject to our returns policy.
