GE Multilin UR9AH UR模块
FUSE ACCESS ANALOG INPUT（保险丝接入模拟输入）控制电源保险丝，可从滑动门下方接入。接受传感器接口的4-20mA模拟输入。VT输入：0-600V，3线或4线电压输入。直接（最高600V）或VT（隔离时大于600V）连接。CT输入：接地：3个隔离相CT输入1个隔离中性CT输入1安培或5安培次级隔离安全和滤波器接地所有输入均符合C37.90和IEC 801-2 EMI、SWC、RFI干扰抗扰度。AC/DC控制电源通用控制电源90-300 VDC 70-265 VAC紧凑型设计面板安装用一个标准型号替换了许多分立组件。程序更新固件闪存存储，用于通过通信端口进行现场更新。允许现场更新产品以获取最新功能。通信双RS485通信端口Modbus协议。通过SCADA系统后端（RS485）进行连续监控。前端（RS232）或后端（RS485）访问允许通过PC或冗余通信同时进行通信。®COM1 COM2/3模拟输出4个隔离的0-1mA或4-20 mA输出代替8个传感器。可编程包括：A、V、W、var、VA、Wh varh、PF、Hz SWITCH INPFUSE ACCESS ANALOG INPUT Control power fuse accessible under sliding door. Accept 4-20mA analog inputs for transducer interface. VT INPUTS: 0-600V,3wire or 4 wire voltage inputs. Direct (up to 600V) or VT (>600V for isolation) connections. CT INPUTS: GROUND: 3 isolated phase CT inputs 1 isolated neutral CT input 1 Amp or 5 Amp secondary Separate safety and filter ground All inputs meet C37.90 and IEC 801-2 EMI, SWC, RFI interference immunity. AC/DC CONTROL POWER Universal control power 90-300 VDC 70-265 VAC COMPACT DESIGN Panel mount replaces many discrete components with one standard model. PROGRAM UPDATING Flash memory storage of firmware for field updating via communications port. Enables product updating on-site for latest features. COMMUNICATIONS Dual RS485 comm ports Modbus protocol. Continuous monitoring/control via SCADA system rear (RS485). Front (RS232) or rear (RS485) access allows simultaneous communication via a PC or for redundant comms. ® COM1 COM2/3 ANALOG OUTPUTS 4 isolated 0-1mA or 4-20 mA outputs replace 8 transducers. Programmable including: A, V, W, var, VA, Wh varh, PF, Hz SWITCH INP
