469-P5-LO-A20-E GE 继电器模块 管理大中型电机
469-P5-LO-A20设定点系统通过为用户提供大量可定制的设置来增加可配置性,这些设置直接影响继电器和电机系统的功能。除其他功能外,还可以分配输入、调整时间间隔、查看或清除数据。设定点可以首先通过继电器的自动配置功能轻松建立,然后随着用户对系统需求的理解进行调整。
469继电器有五个预分配的数字输入和四个可分配的数字输入,总共有九个数字输入。预先分配的五个功能一致,而四个数字输入保持惰性,直到用户进行适当的分配。可分配输入的一些例子包括远程报警功能、远程跳闸功能和速度开关跳闸功能。
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。

The 469-P5-LO-A20 set point system increases configurability by providing users with a large number of customisable Settings that directly affect the functionality of the relay and motor systems. Among other features, you can assign inputs, adjust time intervals, and view or clear data. Set points can be easily established first through the relay's auto-configuration function and then adjusted as the user understands the system requirements.
The 469 relay has five pre-assigned digital inputs and four assignable digital inputs for a total of nine digital inputs. The five pre-assigned functions are consistent, while the four numeric inputs remain inert until the user makes a proper assignment. Some examples of inputs that can be assigned include the remote alarm function, the remote trip function, and the speed switch trip function.
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.
