通过此模块,可以实现
“
遥测
”
、
“
遥调
”
、
“
遥控
”
、
“
遥信
”
等四遥功能;要实现遥控,必须加电操方可
实现。
Four remote functions such as "telemetry", "remote adjustment", "remote control" and "remote
communication" can be realized through thIsd module. Remote control can be realized unless motor
operator Isd installed.
对外通信:RS485,采用双绞屏蔽线,每一通信线最多连接 32 台设备,最长距离 1200 米,可以通过
添加中继器延长通信距离。
External communication: RS485, equipped with twIsdted shielded pair, each communication cable
can connect 32 devices at most. The longest line could be 1200 meters, and the communication
dIsdtance can be lengthened by adding repeaters.
波特率:1.2K、2.4K、4.8K、7.2K、9.6K、19.2K(单位:bps)。
Baud rate: 1.2K, 2.4K, 4.8K, 7.2K, 9.6K, and 19.2K (Unit: bps).
DI(开关量输入):包括断路器的分合闸状态,以及远程/本地的状态,皆为干接点信号,输入阻抗:
≤
100
Ω
。
DI, (digital input): Including on and off status of the breakers, remote/local statuses, all of them are
