      • Operating Temperature: The documented cpu module specification is -40°C to 70°C; verify it against the supplied label before installation.
      The PC-502 Emerson cpu module performs its documented automation, interface, control or monitoring duty within the Westinghouse platform. Its correct operation depends on the relationship between the installed hardware, connected field equipment and approved system configuration. Complete model identification reduces the risk of connector, channel and revision mismatches during maintenance.

      Before installing PC-502, compare the full product label, installed position, terminal or connector arrangement, paired assemblies, firmware or logic requirements and available project records. After replacement, review diagnostics and function-test every affected control, protection, communication or field-signal path before returning the equipment to service.

      The PC-502 Emerson CPU Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      Emerson PC-502 documentation and reference links.Important Notice: The linked information must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.

      For PC-502, state the required condition, quantity, installed position, connected assemblies and document requirements in the written enquiry.

      Apply only parameters supported by the exact PC-502 record or a documented family source. Do not infer electrical ratings or interchangeability from appearance.

      Technical notes

      PC-502 must be selected as the exact cpu module identified by its complete hardware marking. Preserve the Westinghouse receiving position, connected hardware and configuration record during replacement.

      Technical Scope

      PC-502 technical scope: Product Type: CPU Module; Category Series: Westinghouse; Voltage Rating: 48V DC; Frequency: 450 MHz; Operating Temperature: -40°C to 70°C.
