GE Multilin UR9KH工控控制卡件
GE Multilin PQM电能质量计是连续监测单相或三相系统的理想选择。它提供电流、电压、实际功率、无功功率、视在功率、能源使用、功率成本、功率因数和频率的计量。可编程设定点和四个可分配输出继电器允许为特定应用添加控制功能。这包括过/欠电流或电压、不平衡、基于需求的减载和电容器功率因数校正控制的基本警报。使用四个开关输入可以实现更复杂的控制;这些也可用于状态信息,如断路器打开/关闭、流量信息等。作为集成工艺、仪表和电气要求的工厂自动化系统的数据采集设备,所有监控值可通过运行Modbus协议的两个RS485通信端口之一获得。如果直接与PLC接口需要模拟值,则任何监测值都可以输出为4至20 mA(或0至1 mA)信号,以替换多达4个单独的传感器。第三个RS232通信端口从前面板连接到PC,以便其他工厂人员同时访问信息The GE Multilin PQM Power Quality Meter is an ideal choice for continuous monitoring of a single or three-phase system. It provides metering for current, voltage, real power, reactive power, apparent power, energy use, cost of power, power factor, and frequency. Programmable setpoints and four assignable output relays allow control functions to be added for specific applications. This includes basic alarm on over/under current or voltage, unbalance, demand based load shedding, and capacitor power factor correction control. More complex control is possible using the four switch inputs; these can also be used for status information such as breaker open/closed, flow information, etc. As a data gathering device for plant automation systems that integrate process, instrument, and electrical requirements, all monitored values are available via one of two RS485 communication ports running the Modbus protocol. If analog values are required for direct interface to a PLC, any of the monitored values can output as a 4 to 20 mA (or 0 to 1 mA) signal to replace up to 4 separate transducers. A third RS232 communication port connects to a PC from the front panel for simultaneous access of information by other plant personnel
