Measuring point multiplicator Type TMU104V

Part number


Product description

 

The measuring point multiplicator TMU104V measures the temperature at a connected sensor and transduces it into 4 insulated signals Pt100 (RTD). Via interface RS485 it can be used as a simulator for up to 4 signals Pt100.

Overview of functions

  • Measuring input Pt100 (RTD), Pt1000, KTY83 / 84 in 2- or 3-wire
  • Measuring input thermocouple (types B, E, J, K, L, N, R, S, T)
  • Measuring range -199…+850 °C
  • 4 insulated outputs signal Pt 100 (resistance- signal), connection in 2-, 3- or 4-wire
  • Digital display, 3 digits, resolution 1 °C (-19.9 … 99.9 °C: resolution 0,1 °C)
  • Storing of MIN- and MAX- values
  • Universal supply voltage AC/DC 24-240 V
  • Interface RS485 (protocols ZIEHL and Modbus RTU)
  • Housing for DIN-rail or wall-mount, 105 mm wide, mounting height 55 mm

Measuring Point Multiplicator and Transducer
The temperature of the sensor (resistance or thermocouple), connected to the input, is available as signal Pt100 (RTD) at 4 insulated outputs.
Thus allows the connection of other sensors than Pt100 to inputs for Pt100 at other devices.
Normally only one input can be connected to a temperature sensor. With help of TMU104 up to 4 devices (controls, displays, monitoring devices) with inputs Pt100 can be connected to one sensor at the same time.

Simulator for Pt100
Controlled via interface RS485 (protocol Modbus RTU) the TMU1004V can simulate up to 4 sensors Pt 00 (RTD). This allows the application in equipment, that makes automatic tests and calibrations at devices and installations with several inputs Pt100.
