Product Description
The GR8-208 auxiliary relay is used to increase switching capacity, duplicate control contacts, and isolate control circuits from power circuits. When energized by either a 230V AC or 24V AC/DC control signal, the relay switches two independent changeover contacts, allowing multiple devices or higher-current loads to be controlled safely from a single control output. Its slim DIN-rail format and LED indication make it ideal for control cabinets and automation installations.
