Область применения

Digital input modules can be used to connect the control to digital process signals. They are suitable for connecting standard switches and two-wire proximity switches (BERO).

Дизайн

The digital input modules have the following mechanical features:

Compact configuration:
The rugged plastic housing contains:
- Green LEDs to indicate signal states at the inputs
- One red LED each to indicate internal and external faults or errors in modules with diagnostic and process interrupts
- Labeling strips
Simple assembly
User-friendly wiring:
The modules are wired by means of a plug-in front connector.

Функции

Digital input modules convert the levels of the external digital signals from the process into the internal signal level of the S7-400.
