Bosch XI110208 AVIOTEC e-Server 8-Input Digital Expansion Module

It is an expansion module that increases the number of inputs on the AVIOTEC e-server. Its eight digital channels are designed to detect 24 V control signals. It is used in installations where the video-based fire detection system needs to receive commands from other units. Because external signals are carried directly to the server, there is no need to insert a separate conversion layer in between.
