Key Features

• Intelligent and configurable design with indicator and operator panel
• Mechanical position indicator for clear visual feedback
• Fail freeze output keeps the last position when electrical power fails
• Designed for mounting to linear actuators per DIN/IEC 534 / NAMUR or rotary actuators per VDI/VDE 3845
• Plug-in analog position feedback module included

Installation Guide

• Check the actuator mounting standard first, either DIN/IEC 534 / NAMUR or VDI/VDE 3845.
• Connect the air pipe to the 1/4-18 NPT pneumatic port.
• Connect the cable to the 1/2-14 NPT thread for electrical wiring.
• Supply clean, dry air within the 0–6 bar output range.
• Wire the 4–20 mA two-wire input and confirm the signal matches your control system.
• Set the action, characteristic curve, and digital input function via the local panel or PC software.
• Verify the mechanical position indicator after installation and power-up.
