GENERAL
TRX10 is a DIN rail mounted high performance, "all-in-one" 2-wire temperature transmitter. Its high reliability industrial design offers some rare functions, e.g. 4~20 mA or 20~4 mA selection.
TRX10 - TC covers 5 thermocouple types as well as millivolts and has 9 overlapping ranges in °C or °F. It has a voltage linear output.
All selections are made by solder jumpers. 'Fine' ZERO / SPAN potentiometers are provided for calibration. |
