The JUMO Ex-i repeater power supply / input isolating amplifier 707530 is primarily developed for internally safe transmitters and mA current sources installed in potentially explosive locations.It offers capabilities such as being HART capable, getting the SIL2 approval and a universal power supply.
The interconnected 2-wire transmitters are supplied with energy and analog 0/4 to 20 mA measured values that are transmitted from the potentially explosive area to the non-explosive area.
Digital (HART) communication signals can be overlapped over the analog measured value on the explosive or non-explosive side and transmitted bidirectionally. In order to enhance the HART impedance with less protected systems you can attach an extra resistor to the output circuit using a DIP switch on the exterior of the case.
