• The device converts 4–20 mA signals into precise pneumatic valve positioning.
• The design suits demanding industrial control valve applications.

Key Performance Features

• Signal input supports 4–20 mA direct or reverse action.
• Fast response with a 20 ms sampling rate.
• High positioning resolution exceeds 4000 A/D steps.

Control Accuracy

• Characteristic deviation stays within ≤ 0.5%.
• Adjustable tolerance band ranges from 0.3% to 10%.
• Adjustable dead band from 0.1% to 10%.

Environmental Resistance

• Temperature influence remains ≤ 0.5% per 10°C.
• Vibration resistance reaches ±1% up to 10 g and 80 Hz.
• Seismic performance meets DIN/IEC 68-3-3 Class III requirements.

Housing and Protection

• Aluminum enclosure meets IP65 / NEMA 4X standards.
• The design omits mechanical indicators for improved durability.
• Mounting orientation does not affect performance.

Signal, Feedback, and Action

• Electrical input uses an LKS adapter for stable signal transmission.
• Analog feedback provides 4–20 mA two-wire position output.
• Double acting pneumatic control includes a fail freeze safety function.
