TEMPERATURE DISPLAYS - PMT-920
dpstar Thermo Control Electric Sdn. Bhd
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.
