1. INTRODUCTION
The universal temperature transmitter TEX - U1 is used for thermocouple and RTD input
signals transformation into standard current analog output signal 4÷20 mA.
The transmitter can be configure by means of:
•PC’s IrDA port
•Communicator’s IrDA port
2. DEVICE SETTINGS
The TEX-U1’s settings are:
