JUMO Ex-i Isolating Switch Amplifier

The intrinsically safe isolation switching amplifier ensures reliable, galvanic isolation and safe transmission of switching signals in Ex applications. It can be mounted in Ex zone 2 and the sensor can be operated in zone 0. The JUMO Ex-i isolating switching amplifier is ideal for JUMO NESOS float switches with 2 switch contacts and also supports NAMUR proximity sensors.
