Overview of functions
•
Pt100-input 2- or 3-
wire automatic compensation of line up to 500 Ω total resistance ( line)
•
Detection of sensor-break
•
Easy adjustment of Zero and Full-scale by pressing a button
•
Wide measuring-range -200... +850 °C
•
LEDs for display of operative state
•
Analog output 0 ... 20 mA / 4 ... 20 mA. Analog output 0 ... 10 V
•
Housing for DIN-rail or wall-mount, 35 mm wide, mounting height 55 mm
•
Universal supply AC/DC 24-240 V
The sensor changes its resistance with the temperature (app. 0,385 Ohm/°C). The measuring transducer
measures the resistance with a current <1 mA and transduces it into a signal DC 0-10 V or 0/2-20 mA that is
proportional to the temperature. At break of sensor or wire the output signal is app. 22 mA / 12 V, at short
circuit 0 mA / 0 V.
•
The output can be connected to displays, PLCs or monitored for over- or under-temperature.

Important Information
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
Attention!
The device has a universal power supply, that is suitable for DC- and AC voltages.
Before connecting the device to supply- voltage make sure that the
connected voltage corresponds with the voltage on the lateral type on the device.
Observe the maximum temperature permissible when installing in switching cabinet. Make sure
sufficient space to other equipment or heat sources. If the cooling becomes more difficult e.g.
through close proximity of apparatus with elevated surface temperature or hindrance of the
cooling air, the tolerable environmental temperature is diminishing.
To use the equipment flawless and safe, transport and store properly, install and start professionally and
operate as directed.
Only let persons work with the equipment who are familiar with installation, start and use and who have
appropriate qualification corresponding to their function. They must observe the contents of the instructions
manual, the information which are written on the equipment and the relevant security instructions for the
setting up and the use of electrical units.
The equipment is built according to DIN / EN and checked and leave the plant according to security in
perfect condition. If, in any case the information in the instructions manual is not sufficient, please contact
our company or the responsible representative.
To maintain this condition, you must observe the safety instructions in this instruction manual titled
“Important Information”. Failure to follow the safety instructions may result in death, personal injury, or
property damage to the equipment itself and other equipment and facilities.
Instead of the industrial norms and regulations written in this instruction manual valid for Europe, you must
observe out of their geographical scope the valid and relevant regulations of the corresponding country.
