AS-Interface Master/Gateways


Product selector Product overview

By using the ASi Gateways from Bihl+Wiedemann, you can transmit digital and analog data, that has been read remotely through ASi modules, to the host controller, and send the output signals from the host controller to the actuators over the respective bus system.

Our ASi Gateways communicate according to the ASi-3 resp. ASi-5 standard, and therefore ensure optimal data exchange. The Gateways are easily and quickly installed and commissioned.The user benefits from a variety of included diagnostic functions such as duplicate address detection, ground protection, and EMC monitoring, as well as the functionality of an optional PLC.


Double Masters in one gateway are an especially cost-efficient approach. They allow controlling two ASi networks with a single Gateway. Additionally, the “1 Gateway, 1 power supply for 2 ASi networks” version requires only one power supply for both ASi networks.
