Contact Protection

Mains relays expected performance and lifetime are often limited due to arcing at relay contacts. The implementation of effective contact protection extends both mains relay reliability, and operational reliability of the circuit in which it operates.

The first product in this family, IES5541A, relay driver with contact protection, guarantees longer relay life, higher switching rates and significantly lower EMI interference. The IES5541A provides effective arc suppression solution in a wide range of mains relay switching applications where either sensing or logic driven inputs are used.
