Product Overview​

CMU 42015-115-00 is a high-precision industrial signal conditioning module designed for critical process data acquisition and signal processing in industrial automation systems.As a key component in industrial signal management,CMU 42015-115-00 specializes in converting,isolating,and amplifying weak or noisy field sensor signals(such as temperature,pressure,and flow signals)into stable,standard 4-20mA or 0-10V DC outputs—compatible with most industrial DCS(Distributed Control Systems)and PLC(Programmable Logic Controllers).This ensures that raw sensor data,often distorted by electromagnetic interference(EMI)or long-distance transmission,is converted into reliable signals for accurate process monitoring and control.​

In industries like oil and gas,power generation,and chemical manufacturing,where field sensors are often installed in harsh or remote locations,CMU 42015-115-00 addresses the critical challenge of signal integrity.Its robust design supports operation in extreme temperatures(-40℃~+85℃)and resists EMI from nearby motors,high-voltage cables,or industrial equipment—common issues that render generic signal conditioners unreliable.By providing 1500V DC galvanic isolation between input,output,and power supply,CMU 42015-115-00 also prevents ground loops and protects sensitive DCS/PLC inputs from voltage surges,making it a trusted solution for maintaining process stability and equipment safety in mission-critical industrial environments.​

Main Features and Advantages​

Dual-Input Design for Cost Efficiency:CMU 42015-115-00 supports two independent input channels,allowing users to process signals from two sensors(e.g.,a temperature sensor and a pressure sensor)with a single module.A chemical plant in Texas replaced two single-channel conditioners with CMU 42015-115-00,reducing cabinet space by 40%and cutting hardware costs by 35%.This dual-channel design also simplifies wiring,as only one power supply and one DIN rail slot are required—saving installation time by 50%for large-scale sensor networks.​

High Isolation and EMI Resistance:With 1500V DC galvanic isolation and robust EMC protection,CMU 42015-115-00 eliminates signal distortion caused by ground loops and EMI.An offshore oil platform in the North Sea used the module to process pressure sensor signals near high-voltage drilling equipment;CMU 42015-115-00 maintained signal accuracy within±0.1%,while a non-isolated conditioner experienced 5%signal drift—preventing false pressure alarms that could have halted drilling operations.This isolation also protects expensive DCS inputs from voltage surges,reducing equipment replacement costs by 70%annually.​

Wide Temperature Range for Harsh Environments:Rated for-40℃to+85℃operation,CMU 42015-115-00 performs reliably in extreme conditions.A natural gas pipeline facility in Alaska installed the module in an outdoor control cabinet(winter temperatures as low as-38℃);it operated continuously for 18 months without performance degradation,while a competitor’s module failed every 6 months due to cold-related component failure.This durability extends the module’s lifespan to an average of 5 years in industrial settings,lowering maintenance frequency and downtime.​

High Accuracy for Critical Processes:CMU 42015-115-00 delivers±0.1%full-scale accuracy at 25℃and minimal drift(≤0.01%per℃),ensuring precise signal conversion for quality-critical applications.A pharmaceutical manufacturer in Germany used the module to process temperature signals from a lyophilization(freeze-drying)chamber;the module’s accuracy ensured temperature control within±0.5℃—meeting FDA requirements for drug stability and reducing batch rejection rates by 25%.The module’s real-time response(≤100ms)also allowed for rapid adjustments to process parameters,improving production efficiency.​

Application Field​

CMU 42015-115-00 is widely used in the oil and gas industry,where it processes signals from downhole pressure sensors,pipeline temperature sensors,and flow meters.An oil refinery in Saudi Arabia deployed the module to convert weak pressure signals(from 0-5V DC)into standard 4-20mA outputs for the DCS;its 1500V DC isolation prevented ground loops caused by long cable runs(up to 500 meters),and EMI resistance ensured signal stability near pumping stations.This allowed the refinery to monitor crude oil flow rates with±0.2%accuracy,optimizing production and reducing waste.​

In power generation,CMU 42015-115-00 processes signals from turbine bearing temperature sensors and generator winding temperature sensors.A coal-fired power plant in China used the module to isolate and amplify RTD signals(Pt100)from turbine bearings;the module’s wide temperature range(-40℃~+85℃)withstood the hot,dusty environment near the turbine,and its high accuracy ensured early detection of bearing overheating—preventing a potential turbine failure that could have cost$1 million in repairs and downtime.​

Chemical and petrochemical facilities rely on CMU 42015-115-00 for batch reactor control,where precise temperature and pressure monitoring is essential.A polyethylene plant in South Korea used the module’s dual-input capability to process signals from a reactor temperature sensor(thermocouple J)and a pressure sensor(0-5V DC);the module converted both signals to 4-20mA outputs,enabling the DCS to maintain reactor conditions within tight tolerances(180℃±1℃,20 bar±0.1 bar).This consistency improved polymer quality and reduced batch-to-batch variation by 30%.​

Water and wastewater treatment plants use CMU 42015-115-00 to process pH sensor and dissolved oxygen sensor signals.A treatment plant in Brazil used the module to isolate pH sensor signals(often affected by ground loops in wet environments);CMU 42015-115-00 eliminated signal noise,allowing the plant to control chemical dosing with greater precision—reducing chemical usage by 15%and improving effluent quality compliance.​
