Features:
- Ruggedized for Harsh and Hazardous Environments
- Long-Distance Remote I/O Capability
- High System Availability with IOP Redundancy
The Honeywell MC-PRHM01 51404109-175 is conformally coated to protect against corrosion, humidity, and chemical gases (G3 rating). It is approved for Intrinsically Safe (IS) and Non-Incendive (NI) applications, allowing direct mounting in Class I, Division 1 hazardous locations when used with the correct power adapter.
This RHMUX IOP can be located up to 2,000 meters (6,560 feet) from its field termination assembly via a single cable, enabling efficient process monitoring in remote or distributed sites without requiring additional controllers or repeaters.
The module fully supports IOP redundancy, ensuring continuous operation. A secondary Honeywell MC-PRHM01 51404109-175 can be added to seamlessly take over signal acquisition if the primary IOP fails, minimizing process downtime.
The MC-PRHM01 51404109-175 Honeywell Remote Hardened Low Level Multiplexer (RHMUX) may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Oil & Gas Upstream/Midstream: Monitoring wellhead temperatures, pipeline inlet/outlet temperatures, and separator skids in remote, unstaffed locations where long cable runs are required.
- Petrochemical & Refining: Acquiring thermocouple signals from distillation columns and reactors located in Class I, Division 1 hazardous areas using the Intrinsically Safe (IS) power adapter.
- Pharmaceutical & Fine Chemical: Providing galvanic isolation for temperature sensors in stainless steel reactors, ensuring safety in Zone 0/1 environments and maintaining signal integrity.
- Heavy Industry & Power Generation: Installing the remote FTA close to turbines or kilns in high-electrical-noise environments, while keeping the IOP in a controlled central cabinet up to 2 km away.
- True Remote I/O Architecture: The 2,000-meter (6,560-foot) cable distance capability between the FTA and IOP eliminates the need for remote instrument cabins, reducing infrastructure and cabling costs.
- High Channel Density: A single Honeywell MC-PRHM01 51404109-175 supports up to 32 thermocouple inputs, maximizing I/O count per card slot and improving cabinet space efficiency.
- Low Power Consumption: Consuming only 100 mA at 24 Vdc, the module places a minimal load on the system power supply, allowing more power budget for other field devices or FTAs.
- Reliable Signal Acquisition: The system is designed specifically for 0 to 100 mV and thermocouple inputs, ensuring high accuracy and noise immunity for low-level signals often susceptible to interference.
- Conformal Coating (G3 Rating): The Honeywell MC-PRHM01 51404109-175 is conformally coated, protecting the circuitry from corrosion in harsh environments defined by ANSI/ISA-S71.04 (e.g., high concentrations of H2S, SO2, Cl2).
- Hazardous Area Certification: When paired with the MC-GRPA01 (IS) or MC-TRPA01 (NI) power adapters, the overall system is FM-approved for use in Class I, Division 1 & 2, Groups A, B, C, D locations.
- Remote FTA Enclosure: The associated FTA (MC-GRMT01) must be mounted in a NEMA 4 or 4X sealed enclosure (e.g., MU-CMSC03 or MU-CMSS03) provided by Honeywell to maintain its hazardous location approvals and withstand wet or corrosive conditions.
- Wide Operating Temperature for FTA: While the IOP is for cabinet use, the remote FTA, when housed in its certified enclosure, is designed for a wide temperature range and can operate in condensing atmospheres, suitable for direct attachment to process equipment.
