Simplified wiring of input circuitry
Read Technical parameters of inputs before connecting input signals
TeUp can be used for powering of connected device (maximum current see Technical
parameters of inputs ). Default swich position is +24V. If connected devices need lower voltage
(13.8V max), change swich to +12V position.
WARNING
–
wrong manipulation with switch can damage connected devices!
Connection of device with current output (4 to 20) mA to data logger input

by means of current loops connection of device up to 1000m distance is enabled. Mind all
rules of correct routing and connection, especially with longer distances and in environment
with electromagnetic interference.

active current source connect between terminals COM (positive pole) and GND (negative
pole).
