KOSO Positioners

KOSO EP800,Electro-Pneumatic Positioner

Product Introduction
EP800 Series - The pneumatic positioner and the pneumatic actuator supporting the use of 4 ~ 20mADC input signal into an output air pressure to control operation of the actuator. Simultaneous feedback actuators, so that the actuators can be controlled by signals for precise positioning. EP800 Series - The pneumatic positioner can be used for single-action and double-acting pneumatic actuator.
