SPEC for YT****0 SERIES ELECTRO-PNEUMATIC POSITIONER The YT****0 Series Positioner, mounted on a pneumatic 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. 　　The YT****0 can be used with both spring return and double acting actuators. Features ΔLinear ?Pass CE authentication ?Pass explosion proof (ExiaⅡ CT6, ExdⅡ BT6, ExdⅡ CT6) authentication ?Pass IP*6 authentication ?High anti-vibration (none effective in ****0Hz) ?The linking of air duct is perforated form, convenient for the linking in all direction ?Convenient for the transform of positive action and counteraction ?1/2 split range available by simple adjustments without changing parts ?Easy maintenance ?Simple structure for feedback connection Δ Rotary ?Economical energy saving SPECIFICATION YT****0L YT****0R Linear Rotary Single Double Single Double Input signal 4~*0mADC Impedance **0?*5 Air supply 1.4~7kgf/cm （*0~**0psi） Stroke *0~**0mm 0~*0?
