概要 GENERAL 　　 EP800系列电气阀门控制器与气动执行机构配套使用，输入4~20mADC的信号转换输出空气压力，控制执行机构的动作。同时根据执行机构的行程进行反馈，从而使执行机构的行程能 按控制信号进行定位。EP800系列电气阀门******能用于单动作型和双动作型执行机构。　　The EP800 Series Positioner, mounted on a pneumatic actuator,moves the actuator by receiving DC 4~20mA signals from a controller.Also, the function of detecting and returning the actuator displacementprovides accurate positioning in response to DC 4~20mA signals. 　　 The EP800can be used with both springreturn and double acting actuators.

2. 特点 FEATURES 　 1、适用于小容量及大容量的执行机构。 　 2、放大器的耗气量小、容量大。 　 3、可以选择输出特性。 　 4、单作用执行机构在需要反作用控制时，正作用型 放大器很容易变换成反作用型放大器。 　 5、耐压防爆型可在现场进行调整。 　 6、本质安全的结构有着广阔的适用范围。

1、Usable with low to high capacity actuators 　 2、A low air consumption 　 3、Output characteristics selectable 　 4、Reverse action pilot valve easily available 　 5、Anti-pressure andexplosion proof structure marking on-site adjustment possible 　 6、Intrinsically safe construction for a wide scope of applications
