Solid State Relay
ICCS 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. ICCS Solid State Relays provides feedback on the current flowing through the device. This feature allows a diagnostic through a main controller.

- Contact bounce
- Moving parts
- Mechanical wear on the switching contact
- Switching noise
- Direct control by driver logic
- Low power consumption
- Wide operating voltage range
- High shock and vibration protection
- Generating no magnetic fields or electrical interference
