Дизайн

Digital output modules are characterized by the following mechanical features:

Compact configuration:
The rugged plastic housing contains:
- Green LEDs for indicating the signal statuses at the outputs
- One red LED each to indicate internal and external faults or errors, and to display blown fuses and the absence of the load voltage
- Labeling strips
Simple assembly
User-friendly wiring:
The modules are wired by means of a plug-in front connector.

Функции

Digital output modules convert the internal signal levels of the S7-400 in the external signal levels required for the process.
