Safety Relay

NPFSR-K51D.S is a normally closed output safety relay that receives DO signals to achieve reliable isolation control. The field side supports up to 250V AC load circuit. It can be used in safety-related applications of SIL2 and SC2 conforming to IEC 61508 standards and is commonly used in ESD applications in SIS. Main features: support system loop detection function; Support Proof Test function; Apply Fail-safe technology; Output relay double redundancy.
