Solid State Relays

Solid State Relays

Easy Care Perennials

Solid State Relays can be used to switch lamps or resistive loads. In terms of size and pin arrangement, the Solid State Relays are compatible with conventional ISO mini relays. They are maintenance- and wear-free and have a low power consumption.

The Solid State Relays are also short-circuit-proof, overload-proof and protected against overtemperature. Compared to a fuse, the Solid State Relays switch faster in the case of a short-circuit. However, they are not suitable to protect a supply path by themselves and must be pre-fused in advance with a suitable fuse.

Feedback on the current flowing  is possible through the additional fifth pin. This feature allows a diagnostic through a main controller.
