SMART POSITIONER : SS2

Smart performance with 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 ~ +80℃
- 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

Option

- Output position transmitter (4 - 20 mA)
- 2 x alarm limit or micro switch (SPDT)
- By-pass
- Explosion proof type (Exia IIC T6)
- HART communication
- Profibus PA communication (pending)
- Fieldbus FF communication (pending)
