Knick presents Proline P 22400 passive standard signal isolators certified for applications with a SIL3 safety integrity level according to EN 61508. The passive isolator’s safety functionality is the highly precise, linear transmission of 4…20 mA signals with a low transmission error of 0.08 % full scale. 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 connected directly, requiring no elaborate evaluation equipment for redundant structures. The isolator’s robust design ensures excellent availability with a mean time between failures of 965 years.
