Digital Indicator With Relay Outputs – Aplisens PMT-920 Series

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.
