The TXDIN401 and TXDIN402 DIN rail mount transmitters transform a temperature or process signal into a linearized 2-wire loop-powered 4 to 20 mA output. Model TXDIN401 is a temperature transmitter that accepts Pt100 or Ni100 RTD and Types J/K/T/E/R/S/B/N thermocouples. Model TXDIN402 is a process input transmitter that accepts voltage, current or resistance input. The characteristics of these converters ensure high precision on the reading scale with 16-bit conversion. The 4 to 20 mA output can be scaled based on the desired input range.

The programming procedure uses an RFID (NFC) mode with the dedicated TX400-RFID programmer that allows the user to make all calibrations and settings quickly and without the need to power and connect up the transmitter. Simply connect the TX400-RFID programmer to the USB port of your PC, start the RF Programmer configuration software and place the transmitter on top of the TX400-RFID programmer to establish communications. These transmitters are also provided with a data logging function for the input signal. Transmitters have a non-volatile memory (circular buffer) for data-logging with user-selectable sampling time. The user selects the sampling time (1 to 3600 seconds) and then each time the 4 to 20 mA loop powers the device, the input value is stored to non-volatile memory.

An additional programming tool is the Omega Brand Google App - "Direct Link" relying on RFID/NFC connectivity and allowing straightforward programming without wirings by Android devices.

Using the TX400-RFID programmer along with the RF Programmer configuration software (software is a free download from OMEGA) the user can:
• Completely configure the transmitter including scaling the 4 to 20 mA output to desired input range
• Implement field calibration to compensate for gain and offset errors
• Download logged data to PC for visualization and printing

Rated 5 out of 5 by Lee1023 from Wireless configuration We have used at least 20 of these since their introduction, and all are just fine! Love the price and have had no problems other than a loose circuit board in the programmer, fixed that and no problems whatsoever.

Rated 1 out of 5 by ControlEngineer from Programming is easy, but output is not correct We bought 24 of these and a programmer, but 3 units show the same issues. A calibration curve with a known standard shows the output to be linear, but not according to the Type T thermocouple that it was programmed for. Programming for a different thermocouple type yielded the same output. Ice water shows up as -38C, room temperature at a balmy -17C. We will be returning all of them.
