ElectroPneumatic Positioner EP3000

Description

the EP***0 Series Positioner 1. GENERAL 　　The EP***0 Series Positioner, mounted on apneumatic actuator, moves the actuator by receiving DC 4~*0mA signals from a controller. Also, the function of detecting and returning the actuator displacement provides accurate positioning in response to DC 4~*0mA signals. 2.
