The EP800 Series Positioner, mounted on a pneumatic actuator,moves the actuator by receiving DC 4~20 mA signals from a controller. Also, the function of detecting and returning the actuator displacement provides accurate positioning in response to DC 4~20 mA signals.The EP800 can be used with both spring-return and double acting actuators.
EP800：Electro-Pneumatic Positioner
This series is for positioning of pneumatic actuator oper-ated cotrol valves. Input signal 4 to 20mA DC is changed to air pressure. Accurate positioning is achieved by having valve position feedback from valve stem.
