what kind of sensor?from 2 to 4. Transmitter usually 2 wires. Transducer may be 3 or 4, depends. leakage current is 泄漏电流

SENSORSENSOR一般有电感，电容， 磁， 光电感应型等，2线SENSOR通常就象常开/常闭触点，3线，4线SENSOR我指的是NPN/PNP型SENSOR， 电源+，电源-及负载线，第四线DARK ON/LINGHT ON SELECTED（光电型）。TRANSDUCER 一般指压力，位置等模拟信号传感器。

3 wires(Brn, Blu, Blk ): +24v, 0v, output;3 wires(Brn, Blu, Blk ): +24v, 0v, output;
4 wires(brn, blu, blk, wht): PNP/NPN type sensors, blk as P output, wht as N output;
5 wires(brn, blu, blk, wht, grey): the first four wires have same functions as above, the
grey wire as control terminal.
