Order No. 8120.30
Network with up to 200 channels
The OPUS20E is equipped with an ana-
logue input that allows the connection of
2 sensors with voltage and current out-
put, or rather PT100 temperature sensors
in 3 and 4 wire technology.
At the same time up to 4 Lufft tempera-
ture/humidity sensors can be connected
to the datalogger via a serial input.
Each fully equipped OPUS20E is a 10
channel datalogger that can record
various data. It also allows data to be
retrieved online and of ine.
With up to 10 channels per datalogger
transfering data in realtime.
