Product Description

The KOSO EP800 series electro-pneumatic positioners are designed for precise control of pneumatic actuators, converting 4-20mA DC input signals into output air pressure to position control valves accurately. These positioners receive feedback from the actuator's stroke, enabling precise positioning according to the control signal.

Key Features

Precise Positioning: Achieves accurate control with a dead zone less than 0.4% of full stroke and backdrop less than 1% for full travel.
Versatile Input: Supports standard 4-20mA DC signals and split ranges (4-12mA DC, 12-20mA DC, 10-50mA DC for specific models).
Wide Application: Suitable for both straight stroke (12-100mm) and angular stroke (0-90°) actuators.
Flexible Output: Linear output characteristics (configurable to fast open or equal percentage).
Robust Construction: Aluminum alloy housing available in flameproof and normal types, withstanding temperatures from -40°C to 80°C.
