The DT4120 … Resistance Thermometer enable process temperature or resistance value to be displayed on the control panel Pt100 / Pt500 / Pt1000 temperature sensor, resistor or potentiometer can be connected to the input of the instrument, either with 2, 3 or 4 wire.
Large 5 digit, 14.2 mm character height LED display make process value easily visible at a distance.
The instrument is available with the following output options:
• 2 normally open relay contacts (SPST) for limit switching or for simple control tasks
• 0-20 mA / 4-20 mA galvanic isolated scalable current output *
• RS232 / RS485 galvanic isolated communication output with MODBUS RTU slave protocol *
• transmitter supply galvanic isolated 15 VDC 20 mA*.
