Solid-state Relays Output Short-circuit Malfunction 2: What cause an Solid-state Relays output to short-circuit?
An overcurrent flowed through the Solid-state Relays output and damaged the output elements.
1.A short-circuit occurred due to condensation, deterioration of load insulation, temporary short-circuit, or human error.
3.A surge voltage was caused by the load power supply, or other loads connected to the load power supply line.
4.Solid-state Relays were used for an extended period of time in an environment subject to temperature increases.
The rated ON current depends on the ambient operating temperature, type of Solid-state Relays, and whether it has a heat sink. (Refer to information on the load current vs. ambient temperature rating for each Solid-state Relays.)
