FM146B  DEH伺服模块

FM146B伺服单元可接受油动机行程LVDT、FM146B二次油压或油动机滑阀行程等信号作为反馈量。

FM146B伺服单元内部配有2 路LVDT 调制解调电路，FM146B可通过底板上的拨码开关调整LVDT 信号的幅值，通过改变LVDT芯杆的位置来调整信号的零位。

FM146B激励信号为1.7KHz/3.5VAC 左右的正弦波，FM146B二次油压或油动机滑阀行程信号为直流电压或电流，FM146B可通过面板上的电位器调整信号的零位和幅度。

The FM146B servo unit can accept signals such as oil motor stroke LVDT, FM146B secondary oil pressure or oil motor slide valve stroke as feedback.

FM146B servo unit is equipped with 2 LVDT modulation and demodulation circuits, FM146B can adjust the amplitude of the LVDT signal through the dip switch on the bottom plate, and adjust the signal zero position by changing the position of the LVDT core rod.

The FM146B drive signal is a sine wave of about 1.7KHz/3.5VAC, the FM146B secondary oil pressure or oil motor slide valve stroke signal is a DC voltage or current, and the FM146B can adjust the zero and amplitude of the signal through the potentiometer on the panel.
