Digital outputs for the SIMATIC S7-400
For connecting solenoid valves, contactors, low-power motors, lamps and motor starters

Область применения

Digital output modules can be used to output digital signals from the control to the process. They are suitable, for example, for connecting solenoid valves, contactors, low-power motors, lamps and motor starters.

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.
