TRANCEL TMT-2140 is an RTD temperature transmitter designed to convert temperature measurements into high-accuracy digital data and transmit them to PLC systems through RS-485 Modbus RTU. The device supports up to four RTD sensors and can operate with 2-wire or 3-wire PT100 sensors. It provides a measurement range from -200 °C to +800 °C, accuracy of ±0.2 °C and external resolution of 0.1 °C. Lead resistance compensation, sensor wiring failure detection, input surge protection, RFI/EMI screening and isolated serial communication provide reliable temperature measurement over long cable distances and in demanding industrial environments. Its compact DIN-rail design is suitable for asphalt, packaging, oil, gas and petrochemical applications.
