POA – Please submit a RFQ

Siemens SITRANS TR420 transmitters feature dual inputs, offering versatility across various industries. With their compact design, they can be easily mounted on standard DIN rails, in protective boxes, or within control cabinets on-site. These transmitters support a wide range of sensors and signal sources through their universal input module:

  • 2 resistance thermometers (2-wire, 3-wire, 4-wire connection)
  • 2 thermocouples
  • 2 linear resistors, potentiometers, and DC voltage sources
Part Number: SIE_TR420_2493
SIEMENS SITRANS TR420 (HART, Universal) Temperature Transmitter

Benefits

The output signal is a load-independent direct current ranging from 4 to 20 mA, aligned with the input characteristic and augmented by the digital HART signal. Moreover, the dual input mode facilitates drift detection of the inputs, aiding in planning maintenance intervals more effectively.

  • Compact design
  • Connection of two independent input circuits for redundant operation (high input availability)
  • Galvanic isolation
  • Test terminals for ammeter
  • Diagnostics LED (green/red)
  • Input monitoring wire break and short-circuit
  • Self-monitoring
  • Configuration status stored in EEPROM
  • Expanded diagnostic functions, such as slave pointer, operating hours counter, etc.
  • Special characteristic
  • Electromagnetic compatibility according to EN 61326 and NE21
  • SIL2/3
