通用电气 Multilin的 469-P5-LO-A20-E配备增强型面板，是一款专为大中型电机设计的电机保护继电器。继电器本身由 DEMO 金属手提箱保护，具有耐腐蚀、防尘和耐高温的特性。运输时，继电器包装的宽度为 12 英寸，高度为 11 英寸，深度为 10 英寸。此外，包装的重量约为 <> 磅。

该装置通过其保护机制延长电机寿命并减少系统停机时间。其中一些保护功能包括：

过扭矩保护：469-P5-LO-A20-E可以监控扭矩何时超过用户设置的阈值，并保护从动负载免受损坏。

RTD 保护： 469 的 <> 个 RTD 输入是高度可编程的，可以提醒用户危险的环境温度变化。当值达到用户设置的阈值时，可以分配报警、跳闸和高报警功能。

接地故障保护：接地电流检测功能通过从危险电流中移除直流分量来保护设备，从而保护电机免受相地故障的影响。

除其他保护功能外，这些功能可减少系统停机时间并延长电机寿命。

469具有模拟功能，可以测试继电器的有效性，并评估其在当前设定点设置下的工作方式。为输入模拟值;还可以模拟故障条件和跳闸前条件。

关于 469-P5-LO-A20-E的常见问题

GE电机管理继电器469-P5-LO-A20-E上的短路跳闸应该设置什么？

GE 469-P5-LO-A20-E 继电器的短路跳闸必须设置为高于最大锁定转子电流，但也要低于继电器上保险丝的实际短路电流。最大锁定转子电流为 630% 满载电流或 6.3 x 满载电流。请记住，如果锁定转子电流设置为 7 x 满载电流，则会出现跳闸的时间延迟，并且可能具有不对称的启动电流和直流电偏移。如果设置为 7 x 满载电流限制了启动能力，则将 S/C 设置为更高的水平，达到满载电流 （11.1 x 7.6 = 3.11） 的 7 倍以覆盖条件。

469-P5-LO-A20-E GE I/O 增强型面板

Model: 469-P5-LO-A20-E

The 90-30 Series IC693CPU374 module is a single slot CPU (AMD SC250) manufactured by Agfanuc with an embedded Ethernet controller. The CPU 374 module comes with 240 KB of user-configurable memory, 4K I/O, and eight racks. The embedded Ethernet controller supports communication speeds of up to 100 Mbps and comes with a built-in switch. It supports SRTP and Ethernet global data as well as Modbus/TCP client/server protocols. There is no serial port in this module.

Ge Multilin's 469-P5-LO-A20-E with enhanced panel is a motor protection relay designed for large and medium sized motors. The relay itself is protected by a DEMO metal carrying case that is resistant to corrosion, dust and high temperatures. When shipped, the relay package is 12 inches wide, 11 inches high, and 10 inches deep. In addition, the weight of the package is about <> pounds.

The device extends motor life and reduces system downtime through its protection mechanism. Some of these protection features include:

Over-torque protection: The 469-P5-LO-A20-E monitors when torque exceeds user-set thresholds and protects the driven load from damage.

RTD Protection: 469 <> RTD inputs are highly programmable to alert users to dangerous ambient temperature changes. Alarm, trip, and high alarm functions can be assigned when the value reaches a user-set threshold.

Ground fault protection: The ground current detection function protects the device by removing the DC component from the dangerous current, thus protecting the motor from phase-ground faults.

These features, among other protective features, reduce system downtime and extend motor life.

The 469 has simulation capabilities to test the effectiveness of the relay and evaluate how it works at its current set point Settings. Is the input analog value; Failure conditions and pre-trip conditions can also be simulated.

Frequently Asked Questions about 469-P5-LO-A20-E

What should be set for short circuit trip on GE Motor Management relay 469-P5-LO-A20-E?

The short circuit trip of the GE 469-P5-LO-A20-E relay must be set above the maximum locking rotor current, but also below the actual short circuit current of the fuse on the relay. The maximum locking rotor current is 630% full load current or 6.3x full load current. Keep in mind that if the locking rotor current is set to 7 x full load current, there will be a time delay of tripping, and there may be asymmetric starting current and DC current offset. If setting to 7 x full load current limits the ability to start, set S/C to a higher level, up to 7 times the full load current (11.1 x 7.6 = 3.11) to cover the conditions.
