ProLine P 22400

A high level of functional safety can be achieved even in single-channel structure and without diagnostics. For instance, sensors and actuators in safety circuits can be directly connected, requiring no elaborate evaluation equipment for redundant structures. At the same time, the device has a low total failure rate and provides high availability.

Its operating principle enables the implementation of a product that  combines high functional safety with high availability in a unique way – a balancing act that would otherwise be hard to achieve.
