AE402 Relay Box.
The relay box is an add on for the ABK, AFK, Warrior and AE 402 Indicator. When installed it allows the checkweighing limits to trigger a voltage relay. Once the trigger is set the relay box will open or close a switch. This allows the scales to drive other items such as a motor for filling or lights to signal the users. The relay box includes input for power to help drive the relays.
