Actuator-sensor (AS) interface for network with impedance as network closure end, voltage supply and network through, two-wire cable coupled to voltage supply, to which are coupled several communication appliances

摘要

AS interface for network with impedance as network closure end (16), voltage supply (12), to which is coupled through running, two-wire network cable (11), to which are connected several communication appliances of master-slave (13,14) type. In network closing end is fitted voltage comparator, which detects and processes inadmissible voltage drop at network cable. Preferably voltage drop is optically by LED. Comparator result is carried by signal to master (13) via slave in network closing end and cable.
