Specification of rated working voltage
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 this module. Remote control can be realized unless
motor operator is 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 twisted shielded pair, each communication cable
can connect 32 devices at most. The longest line could be 1200 meters, and the communication
distance 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：
≤100Ω。
DI, (digital input): Including on and off status of the breakers, remote/local statuses,
all of them are dry contact signals. Input impedance: ≤100Ω
网络控制选择，即选择远程或本地工作方式，常开为远程，常闭为本地。
Network control selection, namely, selection of remote or local working mode, with normal
open for the remote and normal close for the local.
DO（开关量输出） ：分合闸的控制信号，将来自断路器控制器的电平信号转为干接点信号，触点容量：
阻性负载 DC 30V/5A、AC 270V/3A。
DO (On-off output): Control signal for switching on and off the breaker, transferring the
level signal from the breaker controller into dry contact signal. Contact capacity: resistive
load DC 30V/5A, AC 270V/3A.
DC 5V 输出功率：50mW。
DC5V output power: 50mW.
