• 可编程输出：支持热容量、满载百分比和相电流等参数的编程输出
• 传输器：支持50 MHz/15 W的传输器
• 短路和接地跳闸：S/C跳闸Lvl 1至11 x CT PRI/关闭
• 储存温度范围：-40 到 158°F
• 不平衡延迟：0-60秒可调

二、功能特点

1. 电机保护：GE 239主要用于保护交流电机，特别是三相交流电机，避免因电气故障导致的电机损坏。
2. 多功能：除了电机保护外，它还具有保护相关机械设备、在工艺故障造成损坏之前发出警报、在故障发生后诊断问题以及在日常维护期间验证继电器操作是否正确等功能。
3. 高可靠性：采用先进的处理器架构和多核心设计，提供强大的计算能力，确保设备在各种工况下的稳定运行。
4. 易操作性：配备清晰的前置LCD显示屏，允许用户方便地查看状态、温度和电流等数据。
5. 通信接口：支持ModBus串行通信接口，便于整个工厂的电机启动器连接到中央控制/监控系统，实现连续监控和快速故障诊断。
6. 扩展性：支持现场更新选件和/或MOD，便于用户根据实际需求进行功能扩展。

三、应用场景

GE 239电机保护继电器因其功能多样、编程控制简单，成为各种应用中电机和设备保护的理想选择。典型应用场景包括：

1. 泵和风机保护：利用欠电流功能检测泵和风机的吸力损失或流量损失，提供机械保护。
2. 压缩机保护：利用启动计时器为压缩机电机提供电气保护，防止因出口打开而导致的过长运行时间。
3. 恶劣环境应用：适用于恶劣环境的敷形涂层设计，确保设备在恶劣环境下的稳定运行。

GE 239电机保护继电器凭借其先进的技术规格、丰富的功能特点和广泛的应用场景，成为电机保护领域的佼佼者。
