E/P电气转换器 EP10116/10124/10126
压电先导开关型气压调节模块，实现电信号与气压的转换操作。鲁棒化设计高集成度，连续可靠工作，实现气动功率放大器开/关的高速精确控制，将电信号转化为对应的高驱动力或扭矩，实现阀门定位器或压力控制器在任何条件下的位置驱动。先导供气、排气、参考气压独立管路，利用功率放大器的排气稀释先导供气环境，有效抑制压缩空气中的油、水、灰尘。气路和电路独立于外壳，可以防止压缩空气中的水和冷凝水的影响。带防水PCB的接线罩 EP101-PCB附件，取代普通的PCB端子板，可以让EP电气转换器浸入水下1m，保证可靠工作。EP101-PCB防水附件的安装不影响EP电气转换器原有的尺寸。
