Technical data
Supply voltage:
Connection scheme
Individual operation
Connection scheme
Parallel operation
For operating voltage reverse polarity protection, a one-way rectifier or
­r everse polarity protection diode is integrated in this device variant. This­ ­internal one-way rectifier also allows operating 0 - 10 V devices on AC
supply voltage.
The output signal is to be tapped by a measuring instrument. Output voltage is measured here against zero potential (0 V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage
input UB+ is to be used for 15...36 V DC supply and UB– or GND for
ground wire!
When several devices are supplied by one 24 V AC voltage supply, it is to
be ensured that all ”positive“ operating voltage input terminals (+) of the
field devices are connected with each other and all ”negative“ operating
voltage input terminals (–) (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices
must be referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short-circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
Connecting conditions
Connecting diagram Output: 0 -10 V Without display
Connecting diagram Output: 4...20 mA
Without display
The output voltage follows linear to the temperature signal applied at
the input terminals and generates a proportional output signal of
0 - 10 V. The voltage outputs are short-circuit proof against ground
wire. Applying voltage supply to the output terminals will destroy the
device.
Connecting diagram Output: 0 -10 V With display
Connecting diagram Output: 4...20 mA
With display
In case of the 4...20 mA measuring transducer, display and evaluating
elements are connected in series in the current loop. The measuring
transducer thereby limits the flowing current in variance of the input
signal. 4 mA are for the measuring transducer‘s internal current consumption. The apparent ohmic resistance can either be connected in
the plus or minus path of the measuring transducer. In case of an apparent ohmic resistance in the plus path, power supply and resistance
must not share one ground wire.

safety regulations issued by the VDE, the states, their control authorities, the TÜV and the local energy supply company must be observed.
The buyer has to ensure adherence to the building and safety regu­lations
and has to avoid all dangers of any kind. We do not assume any ­warranty
for faults or damages arising or resulting from improper use of our
equipment or from non-observance of operating instructions. These
­instruments must be installed by authorised specialists only!
Preferably shielded cables should be used in order to prevent
d­ amages/errors. It is imperative to avoid laying parallel with currentcarrying lines. EMC directives must be adhered to.

If the specified approach velocity is exceeded even by a
marginal amount, a negative influence on the lifetime of
the protective tube may result (material fatigue).
Please observe the permissible approach ­velocities for
stainless steel protective tubes (see diagram TH-VA) as

Information for planning and installation
Gas discharges and pressure surge must be avoided as such have negative influence on ­lifetime
or damage protective tubes.
Devices are to be connected under dead-voltage condition. Devices must only be connected to safety extra-low voltage. Consequential damages
caused by a fault in this device are excluded from warranty or liability. Installation of these devices must only be realized by authorized qualified
personnel. The technical data and connecting conditions shown on the device labels and in the mounting and operating instructions delivered

Operating this device close to other devices that do not comply with EMC directives may influence functionality. This device must not be used for
monitoring applications, which solely serve the purpose of protecting persons against hazards or injury, or as an EMERGENCY STOP switch for
systems or machinery, or for any other similar safety-relevant purposes.
Dimensions of enclosures or enclosure accessories may show slight tolerances on the specifications provided in these ­instructions. Modifications of these records are not permitted. In case of a complaint, only complete devices returned in original packing will be accepted.
3Notes regarding mechanical mounting and attachment:
Before mounting, make sure the existing thermometer‘s technical parameters comply with the actual conditions at the place of utilization, in
particular in respect of:
