Isolating Switch Amplifier
Isolating Switch Amplifier

The intrinsically safe isolating switch amplifier is a new addition to the JUMO Safety portfolio that enables reliable, galvanic 3-way isolation as well as safe transfer of switching signals – for both normal and Ex applications. It can be used in an extended ambient temperature range of -40 to +60 °C, has ATEX and IECEx approval, and can also be mounted in Ex zone 2. The connected float switch contact or proximity sensor can be operated up to zone 0. In addition, the JUMO Ex-i isolating switch amplifier has UL as well as DNV GL approval and meets SIL 2 in safety-related applications. A changeover relay with a phase reversal option per channel is available as a switching output.

Reliable in a wide range of applications

A line failure detection system identifies line breaks or short circuits which ensures a high degree of process reliability. This makes the JUMO Ex-i isolating switch amplifier a reliable partner for a wide range of applications in mechanical and plant engineering, the chemical industry, the food technology sector, and many other areas.

By integrating 2 channels in 1 device, the JUMO Ex-i isolating amplifier requires very little space during installation. Its coded screw terminals and simple configuration with DIP switches help to save time during startup. LEDs indicate the respective status directly on the device. The use of a wide-range power supply unit (24 to 230 V AC/DC) reduces storage costs.
