EVOMINI IOCT

IOCT - Rev. 0

EVOMINI IOCT

Signal converter for thermocouple temperature sensors with IO-Link interface (Cold Junction compensation INTERNAL)

Can be configured in three operating modes: IO-Link, 4÷20mA loop powered and switching output with alarm thresholds (SIO). Moulded body with dual M12 connector and IP67 protection degree. External influences such as ambient temperature, vibrations, moisture and EMC interference have minimal influence on the measurement thanks to the compact and robust design. Compatible with Italcoppie TCSV12 sensors series.
