1. Safety instructions
1.1 Symbols
The symbols used in this operating instruction indicate dangers and
they have the following meanings:
Non-compliance could result in functional failures.
Non-compliance could result in functional failures and
injury to personnel.
1.2 Proper use
●
The device is a transducer power supply for the safe isolation of
4…20 mA signal circuits.
●
The device is intended for mounting in industrial installations and
fulfils the requirements according to EN 61010-1.
●
The manufacturer is not liable for damage that is caused by improper
handling, modifications, or improper use.
●
Optional with intrinsically safe input (blue terminals).
This is an “associated apparatus” and must not be installed in
explosion hazardous areas. The output is not intrinsically safe.
1.3 Qualifications of the personnel
Mounting, installation, and commissioning must only be carried out by
properly trained and authorized personnel, who have read and understood
these operating instructions.
1.4 Repairs and modifications
Repairs and modifications must only be carried out at our factory. The
housing must not be opened. There are no configuration or adjusting
elements inside the housing.
We reserve the right to make changes to improve the product.
2. Short description
The device supplies the passive 2-wire transducer (4…20 mA) which
is connected to the input with a DC voltage, and transmits the signal
current galvanically isolated 1:1 to the output. The current in the output
circuit is also supplied by the device. Therefore a passive signal receiver
(4…20 mA) must be connected.
The device is transparent for HART
®
signals in both directions. The
250
Ω
resistor integrated in the output circuit permits communication
with SMART transmitters.
Open circuit and short circuit in the input circuit are indicated locally by
a red LED.
The device is single channel execution and is suitable for mounting on
a top-hat rail.
3. Indicator LEDs
There are two LEDs on the front of the device, which have the following
meaning:
Marking
Color
Meaning
ON
Green
The LED is on when
the power supply is on
Red
The LED is on when
the signal is outside
the normal measuring
range of 4…20 mA

12. Maintenance
The device is maintenance free. Recalibration of the measured signal
is not possible.
