Dwyer 265ER - Manual

The Series 265ER PRECISOR ® II Electro-Pneumatic Positioner is used for
rotary operation of pneumatic rotary valve actuators by means of electrical
controller or control systems with an analog output signal of 4 to 20 mA or split
ranges.
FEATURES
• There is no resonance in the range of 5 to 200 Hz.
• Perform 1/2 Split Control without any other substitutes.
• Easy to adjust zero and span.
• Easy to convert from Reverse Action to Direct Action or vice versa.
• Easy Feedback Connection.
• Fast and accurate response.
• Low air consumption.
• Easy to protect from hunting effect by using output orifice in small size of
actuator.
• Designed as block build structure for maintenance and repair.
