产品详细资料
雷击和接地浪涌电流会在通信链路的远端之间造成巨大的瞬时电压差。出于这个原因,在两个通信端口内部都提供了浪涌保护装置。具有光耦合数据接口的隔离电源也起到减少噪声耦合的作用。为了确保大的可靠性,所有设备都应安装类似的瞬态保护装置。RS232前面板程序端口A 9针RS232C串行端口位于前面板上,用于通过PC进行编程。该端口使用与两个后端口相同的Modbus协议。使用此接口所需的EnerVista 745设置软件包含在继电器中。RS232端口的布线如下图所示,用于9针和25针连接器。IRIG-B是一种标准时间码格式,允许在1毫秒内在连接的设备之间同步标记事件。IRIG时间码格式是串行、宽度调制码,可以是直流电平偏移或调幅(AM)。第三方设备可用于生成IRIG-B信号;该设备可以使用GPS卫星系统来获得时间基准,以便不同地理位置的设备也可以同步。电介质强度电介质强度测试是在制造商对745继电器进行的。没有必要在客户现场再次进行此测试。但是,如果您希望进行此测试,请按照第7-6页介电强度测试中概述的说明进行操作。
Lightning strikes and ground surge currents can cause large momentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communication ports. An isolated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all equipment should have similar transient protection devices installed.RS232 Front Panel Program Port A 9 pin RS232C serial port is located on the front panel for programming through a PC. This port uses the same Modbus protocol as the two rear ports. The EnerVista 745 Setup software required to use this interface is included with the relay. Cabling for the RS232 port is shown below for both 9 pin and 25 pin connectors IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices within 1 millisecond. The IRIG time code formats are serial, width-modulated codes which can be either DC level shifted or amplitude modulated (AM). Third party equipment is available for generating the IRIG-B signal; this equipment may use a GPS satellite system to obtain the time reference so that devices at different geographic locations can also be synchronized.Dielectric Strength Dielectric strength test was performed on the 745 relay at the manufacturer. It is not necessary to perform this test again at the customer site. However, if you wish to perform this test, follow instructions outlined in Dielectric Strength Testing on page 7–6.
