The GI controller is a thyristor-based solid-state relay designed to control 3-phase asynchronous motors in both forward and reverse directions.
It features two control signals and internal logic to ensure that only one direction is selected at a time.
A green LED indicates forward rotation, while a red LED indicates reverse rotation.
The power thyristors are protected from voltage spikes by integrated varistors and RC snubber circuits.
For safety, it is recommended to install three fast-acting fuses between the 3-phase supply and the controller.

Warning: GI models must be used with an appropriate heatsink (sold separately). Installation must follow the instructions and warnings provided in the official installation notes.
