Product Introduction
The SC-UCMX01 (51307198-175) is a universal control module used in Honeywell’s RTU2020 remote terminal unit platform, which is designed for oil & gas production, pipeline monitoring, and remote SCADA applications. It is not a standard Experion PKS C300 controller module, not a C-Series I/O module, and not a generic PLC CPU that can be freely configured like a ControlLogix or S7-1500.
This module serves as the local control and communication processor within the cabinet, handling data acquisition from field devices, executing local control logic, and communicating with the central Experion SCADA system. The platform is purpose-built for remote installations where rapid deployment, standardized configuration, and integration with SCADA asset management are critical.
Because this is a specialized SCADA/RTU module rather than a mainstream DCS controller, documentation is limited and third-party descriptions vary widely. Always confirm the exact part number, firmware revision, and application configuration against the official Honeywell manual before procurement or replacement.
QA/QC Transparency SOP
- Intake & Origin Verification — Record full code SC-UCMX01, P/N 51307198-175, firmware revision, serial number, and physical condition. Reject units with damaged connectors, burnt components, or missing labels.
- Live Functional Testing — Install in a compatible test rack or verified SCADA test bench. Verify module power-up, LED status, and communication with the Experion SCADA host.
- Communication Verification — Test all configured communication interfaces (SCADA uplink, fieldbus, serial ports as applicable). Verify data exchange with the central SCADA system and local I/O modules.
- Firmware/Config Verification — Read module identity, firmware version, and application configuration through the appropriate Honeywell engineering tool. Capture screenshots and save backup records. Flag any revision mismatch against the site standard.
- Final QC & Anti-Static Packaging — Seal in ESD bags with desiccant. Include test report, nameplate photos, firmware revision record, and a “verify with Honeywell manual before installation” warning.

Field Engineer Gotchas
- Not a C300 controller. SC-UCMX01 belongs to the /Experion SCADA platform, not the Experion PKS C300 DCS platform. It will not fit or function in a C300 I/O rack.
- Part number variants exist. Some listings reference 51307195-175 alongside SC-UCMX01. The “-175” suffix and the full code must match your installed hardware. Do not assume cross-compatibility between different P/N variants without OEM confirmation.
- Third-party descriptions are unreliable. Several vendor pages describe SC- as a generic communication module with Modbus/Profibus/RS-485 interfaces, while others call it a CPM/controller module with mixed I/O. These conflicting descriptions highlight the need to verify against official Honeywell documentation.
- Firmware revision is critical. RTU/SCADA modules often require specific firmware levels to communicate with the central SCADA host. A mismatched revision may prevent the module from joining the SCADA network.
- Application configuration is not portable. Unlike a generic PLC, the SC-‘s control logic and communication mapping are configured within the Experion SCADA environment. Replacing the hardware without the correct application download will not restore functionality.
- Spare pool planning requires caution. Because this is a specialized RTU module with limited public documentation, maintain a verified spare with matching firmware and a documented commissioning procedure.
Application Scenarios
- Replaces a failed SC- module in a remote oil & gas wellhead RTU cabinet, restoring local control and SCADA communication for production monitoring.
- Pipeline SCADA station maintenance. Used during planned maintenance to replace aging RTU controller modules in pipeline compressor or metering stations integrated with Experion SCADA.
- Brownfield RTU migration. Procured as a matched spare for sites running cabinets, with firmware revision verified against the existing SCADA configuration database.
- Remote production optimization. Supports rapid deployment of standardized cabinets for new well pads, where the SC- provides local control and integration with the central SCADA asset management platform.
FAQ
No. SC- is a universal control module for the /Experion SCADA platform. It is not compatible with the Experion PKS C300 DCS controller rack.
What is the correct part number?
SC-, P/N 51307198-175. Some listings also reference 51307195-175 — verify the exact P/N against your installed hardware.
Can I use it as a generic PLC?
No. It is a specialized RTU controller module configured within the Experion SCADA environment. It requires the correct application download and SCADA host configuration.
What communication protocols does it support?
The exact protocol support depends on the configuration and firmware. Verify with the official Honeywell manual rather than relying on third-party vendor descriptions.
Is it hot-swappable?
RTU module replacement procedures depend on the specific cabinet configuration and redundancy setup. Follow Honeywell’s documented procedures before removing or replacing the module.
Where can I get the official manual?
Request the hardware and configuration manual from Honeywell or an authorized distributor. Public documentation for this module is limited.
