Description
The 2-channel output signal conditioner is used for
controlling the intrinsically safe (Ex i) I/P converters,
regulating valves, and indicators installed in the Ex area.
Features
For operating the intrinsically safe SMART actuators, the
analog measuring value can be overlayed with digital
communication signals (HART) on the Ex or non-Ex side
and transmitted bidirectionally in an electrically isolated
manner.
–
–
–
–
–
–
–
–
Sockets are integrated into the COMBICON connectors for
connecting HART (HHT) communicators.
–
The device enables open-circuit and short-circuit
monitoring.
–
An open or short-circuited field circuit causes a high input
impedance on the controller side, thus enabling open-circuit
and short-circuit monitoring via the control system.
–
–
The device isolates and transmits 0.2/4 mA ... 20 mA
signals to the Ex area in an with intrinsic safety.
Readiness for operation is indicated via a green LED.
The device is approved for safety-related applications up to
SIL 2 (1oo1) / SIL 3 (1oo2).

To protect the device against mechanical or electrical
damage, install it in suitable housing with an appropriate
degree of protection according to IEC/EN 60529.
During maintenance work, disconnect the device from
all effective power sources.
If the device is not used as described in the
documentation, the intended protection can be
negatively affected.
Thanks to its housing, the device has basic insulation to
the neighboring devices, for 300 Veff. If several devices
are installed next to each other, this has to be taken into
account, and additional insulation has to be installed if
necessary! If the neighboring device is equipped with
basic insulation, no additional insulation is necessary.
The voltages applied at the input, output, and power
supply are extra-low voltages (ELV). Depending on the
application, it can be the case that a voltage that is
dangerous to the touch (>30 V AC / >60 V DC) against
the ground could be present on the device. In this case,
a safe galvanic isolation exists between the input side
and the output side.

Electrostatic discharge
NOTE: Electrostatic discharge
The device contains components that can be
damaged or destroyed by electrostatic discharge.
When handling the device, observe the necessary
safety precautions against electrostatic discharge
(ESD) according to EN 61340-5-1 and IEC 613405-1.

Simple or redundant diode-decoupled power supply is
possible.
Depending on the current consumption of the modules, up
to 150 individual modules can be supplied by a supply that
is protected by a fuse.
The module has integrated error evaluation. An auxiliary
supply failure or fuse fault is indicated at a relay contact and
displayed via a flashing LED.
