Please enter your configuration requirements below (see table for options). Enter "Not Required" if configuration is not required. Examples: Thermocouple Type K, 0 to 180 and Pt100 3-wire, -50 to 300

Configuration requirements:  

Quantity:
The TXDU2 DIN rail mounting isolated transmitters are microprocessor based and fully linearised. As standard they feature a universal 2-wire, 4~20mA output (loop power) and universal input which accepts the following:

• RTD (Pt100 or Pt1000)
• Thermocouple (Types K, J, T, N, E, R, S, B)
• Millivolts (mV)
• Milliamps (mA)
• Voltage (V)
• Potentiometer

We can offer the following pre-configuration options (note: temperature range must fall within minimum/maximum range for an input)

Input TypeMinimum TemperatureMaximum Temperature
Thermocouple Type K-200°C+1372°C
Thermocouple Type J-100°C+1200°C
Thermocouple Type T-200°C+400°C
Thermocouple Type N-180°C+1300°C
Thermocouple Type E-100°C+1000°C
Thermocouple Type R-50°C+1760°C
Thermocouple Type S-50°C+1760°C
Thermocouple Type B0°C+1820°C
Pt100 3-wire-200°C+850°C
Pt1000 3-wire-200°C+850°C

The units are loop powered, 10-36 V DC and can be supplied configured to suit your application requirements (simply enter your configuration requirements above) or can be easily configured yourself using the TX-USB Configuration Kit which is available separately. Simply install the software (which is available for free download from our website), connect the USB configuration module and plug the lead into the transmitter. The software will then provide the necessary prompts.
