VISY-Output 4 is a quad relay output module installed in a splash-proof hausing.
VISY-Output 4 serves as a link between the tank level gauge VISY-X and external safety equipment or alarm indicators. Each of the 4 relays can me mapped to different alarm conditions detected by the tank level gauge VISY-X. As VISY-Output 4 has its own housing it can be installed at the position where it is needed. The connection to the tank level gauge VISY-X is done by a cost-efficient two-wire cable.
