Failsafe digital input modules convert the levels of the external digital signals from the process into the internal signal level of the failsafe SIMATIC S7 CPUs.
The safety functions required for failsafe operation are integrated in the modules.
Compact configuration: The rugged plastic housing contains
Green input signal status LEDs
Green LED for indicating safety mode
Red group fault LED
Slot for front connector protected by the front cover
Labeling area on the front cover
Easy installation: Installed in the same way as the other ET 200M I/O modules
User-friendly wiring via front connector
Fail-safe digital input modules are suitable for connecting
Switches and 2-wire proximity switches (BEROs)
Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas
The modules are implemented centrally with SIMATIC S7-31xF-2 DP and in the ET 200M distributed I/O station in combination with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH. They can also be used in non-safety-relevant standard mode and then respond like standard S7-300 modules.
