Wiring instructions Digital Inputs
The input filters used eliminate interference pulses. In addition, careful wiring is recommended in order to
guarantee perfect operation.
The following
guidelines
must be observed:
Eliminate parallelism of input lines with load circuits or AC lines.
Correct grounding
General information about the relay outputs
All relay coils are supplied by the internally gen24 V DC. The conductor cross section of the relay
outputs is designed for the maximum continuous loads according to the specifications of the relay outputs for
the loads listed at 230 V AC. It should be noted that thermal loads act on the conductor lines at higher currents
and this can lead to their destruction in the event of permanent overload! Higher voltages can lead to leakage
currents or flashovers between the different potentials!
In order to guarantee correct functioning, it is essential to observe careful cable routing.
Eliminate parallelism of load circuits with input lines.
Wiring instructions for analog input
The signals that can be captured by the analog input are very small compared to the digital signals. In order
to guarantee correct functioning, it is essential to observe careful cable routing.
The connecting lines to the analog signal sources must be as short as possible and must be routed to
digital signal lines or alternating current lines, without parallel routing.
The signal lines should be shielded with 2 poles.
Temperature measurement with thermocouples
Temperature measurement with thermocouples is based on the temperature-dependent voltage that occurs
at each connection of two conductors made of different metals (alloys) (Seebeck effect).
