Evominiserc-Rtd

Programmable temperature signal converter with RTD input and Modbus RTU digital output (RS485)
By using a single cable, it is possible to build a sensors network which can be directly connected to a PLC or a PC equipped with a supervisory software (SCADA). These devices are equipped with M12 connectors allowing for an easy and quick installation with degree of protection IP67. It is compatible with Italcoppie TRM and TRC probe series.
