Main Functions

Multi‑type temperature sensor signal acquisition: Accept input signals from RTD resistance thermometers (2‑wire / 3‑wire /4‑wire), thermocouples, potentiometers, resistance‑type sensors and mV‑level low‑voltage sources; also support differential‑temperature measurement.
Thermocouple cold‑junction compensation: Matched with dedicated CJC plug for accurate cold‑junction compensation, eliminates temperature‑drift error for thermocouple measuring loops.
Signal conversion & galvanic isolation: Perform three‑port electrical isolation between sensor input, power supply and analog output circuits. Convert raw temperature sensor signals into standard 4‑20 mA / 0‑10 V analog process signals for DCS / PLC systems, suppress ground‑loop interference and industrial surge noise.

Phoenix Contact MACX MCR‑T‑UI‑UP

Limit‑value relay alarm output: Built‑in one‑channel form‑C relay contact output, configurable high‑limit / low‑limit alarm trigger for temperature over‑range interlock or local alarming.
Flexible free‑programming support: Parameter setup via FDT/DTM software or portable IFS‑OP‑UNIT operator panel; support reverse‑scale output, custom measuring range definition, parameter modification during operation without shutdown.
Wide‑range universal power supply: Accept wide‑range power input 19.2‑253 VAC / DC, adapt to diverse industrial cabinet power‑supply conditions.
Hardware self‑diagnosis & status indication: LED indicators for power status, sensor fault and module failure. Detect sensor open‑circuit, short‑circuit and internal hardware anomalies, trigger relay alarm for measuring‑loop failuresdocs.
Functional‑safety compliance: Meet SIL 2 safety requirement per EN 61508; allow installation in Zone 2 hazardous‑area cabinets under ATEX / IECEx certification.plcva.com

Phoenix Contact MACX MCR‑T‑UI‑UP

Matched field sensors: PT100/PT1000 RTD sensors, multiple‑type thermocouples, resistance‑based measuring sensors in process sites.plcva.com
Upper‑level control devices: DCS, PLC, SCADA and process‑monitoring systems.
Target industries: Thermal‑power plants, petrochemical plants, chemical‑processing facilities, pulp‑and‑paper mills, metallurgy, pharmaceutical factories and general‑process‑industry sites.
Purpose: Realize temperature‑signal conditioning, isolation and standard‑signal conversion. Deliver accurate temperature‑measurement data for process‑monitoring, closed‑loop regulation and over‑temperature interlock‑protection loops. Eliminate interference of long‑distance field‑wiring, guarantee measuring‑loop stability for automation systems. Serve as spare‑part for existing analog‑signal‑conditioning installations.
