SCR430T属于工业自动化与控制的监控器-继电器输出。由力特公司制造生产的SCR430T监控器 - 继电器输出继电器输出监控器检测工业继电器的异常输出，并触发逻辑输出或触头组。常见的检测类型包括：AC 和 DC 电流或电压、电压不对称、接地故障、温度监控、缺相，以及相位序列或不平衡。这些器件可根据跳闸范围、延迟时间、供电电压、安装类型和开关电路进行选择。

描述 Description

The SCR series is a universal lamp alarm relay designed to

sense the failure of flashing or steady incandescent beacon

lamps or steady side lights. The toroidal current sensor provides

isolation and allows monitoring of more than one line at a time.

The SCR Series energizes when one or more lamps fail. It will

monitor the operation of one to four side lights and up to four

beacon lamps.

Operation

When a lamp fails, the SCR Series senses a decrease in current

flow. After a fixed time delay, the LED glows and the two alarm

outputs energize. The outputs and the LED are reset when

the failed lamps are replaced and the current returns to the

nominal setting, or when the input voltage is removed. The SCR

will sense an open flasher, it will not sense a continuously ON

flasher (see FB Series).
