Climate class
Measured value collector for recording and storing
analogue and digital values
Data-logger
Measured value recording using analogue/digital
conversion. The measured values are updated every
second and, after a selectable storage cycle time, are
stored in an internal memory, which can store 16000
measured values (optionally 64000 measured values)
either continuously or in the event of a set point
infringement. Data can be transferred to a Personal
Computer using the software package. This means
the data can then be processed further.
Analogue: Data-logger and separate 0/4...20 mA,
0...1 V and Pt100 transmitter
Digital: Data-logger and potential free contact
RS 232 max. cable length 8 m,
a complete RS 232 interface cable 1.5 m long is
optionally available
Universal application
analogue: transmitter must have 0/4...20 mA, 0...1 V
output signal or direct Pt100
digital: potential free contact or 5 VDC TTL peak
Note: The Datalogger has no loop power supply
Digital input: 1
0...1 V, R >= 1 MOhm

Accuracy +/- 0.25 % FSD
0/4 mA...20 mA,via shunt, R
Cable open circuit monitor < 2 mA (on 4...20 mA)
Accuracy +/- 0.25 % FSD
Pt100, -100...+400 °C, screened cable
Accuracy +/- 0.5 °C, Cable open circuit monitor
1 input using two terminals, f
for potential free contact
Temperature drift +/- 0.25 % / 10 K
+/- 50 ppm (<= 30 min/year)
The unit should be mounted vertically, for this a wall
or stand pipe mounting kit can be ordered.
