The life of a relay is strongly dependent on its operating conditions. The magnitude of the switched load, the switching frequency and period and the ambient temperature are typical influencing variables. They determine the power dissipation introduced by
the electric arc, the resulting contact temperature and wear. In safety critical applications, specialized types of relays show the failure state securely by restraint-guided contacts based on the physical design and the assigned circuit. To predict component failure before it occurs, a simulation model fed by actual load data shall compute the true state. Based on these conditions, this simulation model computes the actual wear of the contacts and the remaining life of the relay system for predictive maintenance.
