Ex-i isolating switch amplifier
May 2021
Sensors & Transducers
The two-channel Jumo Ex-i isolating switch amplifier represents a new product category within the extensive Jumo portfolio. It was developed especially for the float switches from the Jumo NESOS series, but also supports all proximity sensors in accordance with the NAMUR standard.
The intrinsically safe isolating switch amplifier, a new addition to the Jumo Safety portfolio, enables reliable, galvanic three-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 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.
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 two channels in one device, the amplifier requires very little space during installation. Its coded screw terminals and simple configuration with DIP switches help to save time during start-up. LEDs indicate the respective status directly on the device, while the use of a wide-range power supply unit (24-230 VAC/DC) reduces storage costs.
