Power supply The next few pages show circuit diagrams for the
following power supply arrangements:
Figure 11:
Common power supply for the PS4-200 and the
digital inputs/outputs wired for grounded operation
Figure 12:
Common power supply for the PS4-200 and the
digital inputs/outputs wired for non-grounded
(floating ground) operation
When you use the PS4-200 together with local
expansion modules, you must install the
controller horizontally.
An insulation monitoring device must be installed
if the supply voltage is not grounded (EN 60204,
Part 1 and VDE 0100, Part 725). For floating
operation, the 24 V DC power supply must be a
safety extra-low voltage version to IEC 364-4-41.
