Controller Design
All the controllers in the series have the same basic design. The main functional elements and
assemblies are described in the glossary in the appendix.
2.6.1
Input and output circuits
The
input circuits
use floating inputs. They are electrically isolated from the other circuits of the
PLC with optical couplers. The
output circuits
use either relay or transistor output technology.
The transistor outputs are also electrically isolated from the other PLC circuits with optical
couplers.
The switching voltage at all the digital inputs must have a certain value (e.g. 24 V DC). This volt-
age can be taken from the PLC’s integrated power supply unit. If the switching voltage at the
inputs is less than the rated value (e.g. <24 V DC) then the input will not be processed.
The maximum output currents are 2 A on 250 V three-phase AC and non-reactive loads with
relay outputs and 0.5 A on 24 V DC and non-reactive loads.
