Analog and Modbus Amplifier for strain gauge sensors reference TR FO RS485

Analog and Modbus Amplifier for strain gauge sensors reference TR FO RS485

The TRFO RS485 is a gauge bridge converter.

The measurements made are in 6-wire or 4-wire technology and are available via the Modbus-RTU serial protocol or the analog output.
The analog output is configurable in 0/4..20ma or +/-10V.

The sensitivity from 1 to 64mV/V, configurable by DIP switch for integer values or via software for real values.

We ensure the calibration of this module at our metrology laboratory.
