Moreover, a host of measures guarantee a high standard of operational reliability, even under extreme industrial
environmental conditions. In addition to integrated safety systems, such as:
- Watchdog monitoring of the processor, or
- Monitoring the supply voltage, in particular, comprehensive EMC measures, for example, a new shielding concept.
There is a separate shield connection option for each input, without extra external wiring necessary. The connection to
protective earth ground is created automatically when the module is snapped onto the DIN rail.
