Integrated Power Supply
For modular devices, the following printed circuit-board assemblies have a power supply:
PS201 – Power supply of the base module and of the 1st device row
PS203 – Voltage supply of 2nd device row
CB202 – Plug in module assembly with integrated power supply, for example, to accommodate communica-
tion modules
