Introduction
Load current supplies do not have a connection to the backplane bus of the S7-1500
automation systems/ET 200MP distributed I/O system and therefore do not occupy a
configurable slot. The system power supply, CPU, interface module and input and output
circuits of the I/O modules are supplied with 24 V DC by the load current supply.
Requirements
The mounting rail is installed.
