Gateways

With the ASi gateways from Bihl+Wiedemann you can transmit digital and analog data which have been read remotely through ASi modules to the host controller and set the output signals from the host controller to the actuators over the respective bus system.

Our gateways communicate according to the ASi-3 resp. ASi-5  standard and therefore ensure optimal exchange of the data. They are simple and quick to install and commission. The user benefits from the variety of standard implemented diagnostics functions such as duplicate address detection, earth fault and EMC monitoring as well as an optional PLC functionality.

Double Masters in one gateway are an especially cost-efficient approach. This allows two ASi circuits to be controlled by one gateway. The “Integrated decoupling, ASi current” version also requires just one power supply for both ASi circuits.
