JUMO Ex-i Power Supply/
Input Isolating Amplifier
Brief description
The JUMO Ex-i power supply/input isolating amplifier 707530 is designed for operating intrinsi-
cally safe transmitters (Ex-i) and mA current sources installed in potentially explosive (Ex) areas.
The connected 2-wire transmitters are supplied with energy and analog 0/4 to 20 mA measured
values are transmitted from the potentially explosive area to the non-explosive area. The external
connection defines whether the device operates in supply isolating amplifier mode or isolating
amplifier mode. The output of the module can be operated in active or passive mode. Digital
(HART) communication signals can be superimposed over the analog measured value on the Ex
or non Ex side and transmitted bidirectional.
To increase the HART impedance in low-resistance systems an additional resistor can be acti-
vated in the output circuit using the switch on the device's front. The device provides a 3-way
electrical isolation and the energy supply is designed as wide range power supply (24 V to
230 V).
