Application
Application
Measured value collector for recording and storing
analogue and digital values
Equipment
Data-logger
Operation and
system
construction
Principle
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.
Measurement
system
Analogue: Data-logger and separate 0/4...20 mA,
0...1 V and Pt100 transmitter
Digital: Data-logger and potential free contact
Interface
RS 232 max. cable length 8 m,
a complete RS 232 interface cable 1.5 m long is
optionally available
Inputs
Input
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
Number of inputs Analogue input: 1
Digital input: 1
