ADDRESSABLE RELAY MODULE FOR CIRCUIT BREAKERS

摘要

An addressable relay module (10) is provided for controlling a plurality of relay outputs (14) associated with an electronic circuit breaker system using a trip unit for monitoring system functions or network parameters. The relay module (10) is linked to a multi-drop serial communications network (18) through which data pertainin g to system functions is relayed to and from a communications microcontroller (12) which controls the operational status of relay contacts (14) linked thereto. The microcontroller (12) addresses specific ones of associated relay outputs (14) in accordance with address information contained within the network data. The addressable relay module (10) effectively maps the plurality of relay contact outputs (14) linked thereto to a corresponding plurality of network device parameters ( 18) received through the multi drop network (20).
