Design and functions
Digital input/output modules exhibit the following mechanical characteristics:
Compact design
The rugged plastic housing features:
• Green LEDs for displaying the signal states at the inputs/outputs
• Slot for the front connector, protected by the front cover
• Labeling area on the front cover
Easy assembly
The modules are mounted on DIN rails and connected to adjacent modules via bus connectors. There are no slot rules, the input addresses are determined by the slots.
When used in the ET 200M distributed I/O station together with active bus modules, the modules can be hot-swopped during operation without affecting the other modules.
User-friendly wiring
The modules are wired by means of a front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. When the module is replaced, the front connector can be used in its fully-wired state for a new module of the same type.
