The modules are mounted on the standard rail and connected to neighboring modules via the bus connector. There are no slot rules and the addresses of the inputs are assigned via the slot.
By using them in the distributed I/O station ET 200M in combination with active bus modules, the modules can be replaced during operation with the equipment live. The remaining modules continue to operate.
User-friendly wiring
The modules are wired up via a front connector. When it is plugged in for the first time, a coding device latches in the connector so that the connector will only fit onto modules of this type. When the module is replaced, the fully wired front connector can be plugged into the new module of the same type.
In the case of fail-safe input modules, the necessary encoder power supply (test outputs) are provided. These test outputs can be activated via parameterization.
