PMAC770多功能电力监控仪是一种简单可靠的测控装置,可广泛应用于电力系统、环境
监控、低压配电等自动化领域。
它实现了如下的功能:
◇ 实时参数测量
◇ 电度计量(包括实时电度、复费率电度、历史电度、谐波有功电度(1st~13th))
◇ 电能质量分析
◇ 需量统计
◇ 最值统计
◇ 时钟和事件记录
◇ 定值越限
◇ 相序检测
◇ MODBUS通讯或DLT645-2007通讯1
◇ 数字量输入(DI)、数字量输出(DO)2
◇ 模拟量输入(AI)、模拟量输出(AO)3
◇ 有功、无功2路脉冲输出4
1111....1111测测测测量量量量
PMAC770提供全方位的测量功能,可以充分满足低压或者高压三相电力网络中电气监控
的要求。仪表提供的测量功能如下表所示:
1本体上提供1路MODBUS通信,扩展模块提供额外1路MODBUS通信或DLT645-2007通信。
2本体上提供3路DI和2路DO(基本型除外),扩展模块最多可再提供8路DI或者2路DO。
