RTD thermometer DT4120 series

Pt100with LED displayanalog output

• 2 / 3 / 4 wire measurement • 0.1 °C resolution • 0-20 mA / 4-20 mA, galvanic isolated output (optional) • 2 limit relay outputs (optional) • 96 × 48 mm panel instrument, < 50 mm built-in depth • 18-40 V AC/DC, 180-250 V AC/DC power supply 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*.
