Introduction
Smart performance with flameproof enclosure and innovative and ever-strong coil module even
under harsh working environments
Features
- Easy and quick auto-calibration
- Detecting RA (reverse acting) or DA (direct acting) automatically
regardless of wrong air connections
- Available to use for single or double acting without any special adjustments
- Compact design allowing to be installed on small actuators
- Providing error messages against performance failures
- Possible to test the actuator with any fixed signal under a test mode
- Programmable characteristic curve with 17 points
- Wide operating temperature range -30 ~ +75℃
- Improved control of high-friction globe and ball valves by eliminating
an overshoot and a hunting
- Low air consumption
- Providing a mounting bracket to meet IEC 60534-6-1 for linear valves
- Supporting a NAMUR mounting pattern VDI/VDE 3845 (IEC 60534-6-2)
and providing a multi-size mounting bracket for rotary valves
