Thông số kỹ thuật P 22400 Knick

Functional safety and maximum availability can go together

Passive isolators with a technologi-cal advantage: fewer parts mean rare failures.
For measurement and safety reasons, analog signals are routinely isolated in industrial facilities.
The requirements on plant and safety-related circuits are continuously increasing, for instance because of a growing awareness of occupational safety. Thereby, the technical require-ments on components are also being raised. However, higher functional safety is often bought by more effort and at the expense of availability. This does not have to be the case, as proven by the new ProLine P 22400 passive isolator for standard signals. 
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.
