Digital Indicator With Relay Outputs – Aplisens PMT-920 Series


  •  Input Pt100 2-, 3-, 4-, wires
  •  2 relays outputs: 1A, 230 V AC
  • Power supply: 230 V AC ± 10%/1.5VA

The programmable two relays indicator PMT-920 is designed for temperature measurement. It communicates with resistor-type Pt100 sensors where connection can be made with 2, 3 or 4-wires line. The indicator automatically recognizes a 3 or 4-wire system and compensates resistance of the sensor line. Additionally, two threshold limits can be programmed within the converter to control relay-type outputs. Exceeding the threshold actuates the outputs and is indicated on the front panel of the device. The relay-type outputs have 1 pair of NO contacts.

The PMT-920 display enables programming the following parameters:

  • Tripping levels and hysteresis for the output relays.
  • Status of tripped contacts.
  • Password to disable unauthorized access to the software menu.
  • Filtration degree of indications.
