铁路和工业的绝缘协调
P52000 VPD 用于检测电压。将输入信号与阈值进行比较，并以电气隔离方式将得到的二进制信息传输到输出电路。如果输入电压超过可调阈值，就会打开固态继电器，以此发出输入端有电压的信号。
例如，固态继电器的信号可以控制硬件继电器，或被输入到保护设备或控制器中。信号电平基于 PLC 信号输入类型 1，EN 61131-2。
阈值对于输入电压的量值有效，与符号无关。这就是说，一旦超过正阈值或者低于负阈值，就会触发固态继电器。
可以借助设备正面的旋转编码开关选择 10 个预定义的阈值。也支持用户自定义值。
P52000 VPD 在输入、输出和电源之间有电气隔离（3 端口隔离）。
