Product Introduction
The SC-UCMX01 is the brains inside a Honeywell RTU2020 — the controller CPM that executes the control logic, manages the 28 mixed I/O channels, and communicates with the upstream SCADA system. It belongs to Honeywell’s ControlEdge RTU2020 family, which is designed for remote oil and gas production, pipeline monitoring, and distributed SCADA applications where a full DCS rack is impractical.
The RTU2020 platform integrates with Experion SCADA and is built for rapid field deployment — standardized hardware, factory-tested assemblies, and simplified commissioning. The SC-UCMX01 CPM is the processing core of that assembly. It is not interchangeable with the Experion PKS C300 controller (CC-PCNT01) or any C300 PM I/O module. If you are replacing a failed controller, the firmware revision, MAC address assignment, and I/O configuration all need to match the installed system before the module can be commissioned.
QA/QC Transparency SOP
- Intake & Origin Verification — Record full model SC-UCMX01, part number 51307195-175, serial number, firmware revision, and MAC addresses. Inspect for connector damage, corrosion, or prior rework.
- Power-Up Test — Apply 24 VDC (within 16–30 VDC range) and confirm normal boot sequence, LED status, and power draw within spec (~4.6 W).
- Communication Verification — Verify Ethernet/serial port responsiveness and MAC address readability. Confirm the module can be discovered by the /Experion SCADA configuration tool.
- I/O Functional Test — Stimulate available DI/AI channels and verify DO/AO response where accessible. Check for stuck channels, shorted outputs, or abnormal analog readings.
- Final QC & Anti-Static Packaging — Photograph nameplate (including MAC addresses), PCB condition, and test readings. Pack in anti-static shielding with rigid protection. Include a test summary and traceability record.
Field Engineer Gotchas
- Not a C300 controller — The part number 51307195-175 and “SC-” prefix identify this as an CPM, not a CC-PCNT01 C300 controller. Do not attempt to install it in a C300 IOTA.
- Not a generic communication module — Some third-party listings describe the SC-UCMX01 as a Modbus/Profibus communication card. It is a controller CPM with integrated I/O management. Those listings are misleading.
- MAC address matters — The module carries a dual MAC address pair. In a redundant or networked configuration, the MAC addresses must be documented and correctly registered in the SCADA configuration.
- Firmware revision lock-in — firmware revisions are not always forward/backward compatible. A replacement module with mismatched firmware may require an upgrade or downgrade before it can join the existing assembly.
- Supply voltage range — The 16–30 VDC input range is wider than typical 24 VDC-only modules. Verify the field supply is within spec before applying power to a replacement unit.
- Environmental rating — The -40°C to +75°C operating range reflects RTU field deployment. A module pulled from a heated control room may have seen different stress than one from an unheated wellhead cabinet.

Application Scenarios
- Remote wellhead RTU replacement — Swapping a failed CPM in an assembly at an unmanned oil or gas production site.
- Pipeline SCADA expansion — Adding or replacing an controller when extending monitoring coverage along a pipeline corridor.
- — Pre-staging a replacement SC-UCMX01 with the correct firmware revision before a scheduled site visit to minimize downtime.
- Spare parts validation — Bench-testing a surplus SC- to confirm power-up, communication, and I/O functionality before deploying it to a remote site.
FAQ
No. It is a Controller CPM for the Honeywell / ControlEdge platform, not an Experion PKS controller.
What does “28 mixed I/O” mean?
The module supports up to 28 mixed I/O channels — a combination of digital and analog inputs/outputs. The exact mix depends on the assembly configuration.
What is the supply voltage?
16–30 VDC, with approximately 4.6 W power consumption.
Does it have MAC addresses?
Yes. The module carries a dual MAC address pair, which is used for network identification in the /SCADA system.
No. The SC- is designed for the platform. It is mechanically and electrically incompatible with IOTAs.
Is surplus stock safe to use?
Yes, if it passes power-up, communication, and I/O testing, and the firmware revision is compatible with the installed assembly. Always verify the MAC addresses and firmware before deployment.
Do you supply calibration certificates?
This is a digital/controller module, not an analog measurement instrument, so formal calibration certificates typically do not apply. A functional test report with power, communication, and I/O verification is the appropriate documentation.
