Description
Central unit AHD 882 is a microcontroller-operated device, designed for acquisition, processing and distribution of binary status data and analog limit values (alarms, events, messages, etc.). The data (e.g. measuring point data from sensors of a ship alarm, monitoring and control system) is serially transmitted from decentralized connected external data acquisition stations and processing devices and is processed by integrated alarm, display and control management.
