Repeater power supply and input isolating amplifier,
Ex i
Data sheet
The repeater power supply and input signal conditioner is
designed for the intrinsically safe (Ex i) and electrically
isolated operation of measuring transducers and mA current
sources installed in the hazardous area.
2-wire measuring transducers are supplied with energy via
a powered input with intrinsic safety.
4-wire measuring transducers and mA current sources can
be operated via a non-powered input.
The analog 0/4 ... 20 mA measured value from the
hazardous area is electrically isolated 1:1 when transmitted
to the non-hazardous area.
You can operate the output of the module actively or passively.
The analog measured value on the Ex or non-Ex side can be
overlayed with digital (HART) communication signals and
transmitted bidirectionally.
You can connect additional resistance in the output circuit in
order to increase the HART impedance in low-ohmic
systems using a terminal point.
Sockets are integrated into the COMBICON connectors for
connecting HART (HHT) communicators.
The devices are certified for safety-related applications up
to SIL 2 in accordance with IEC/EN 61508.
