CYLINDER POSITIONER

SS2-Cylinder

Introduction

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
- Providing error messages against performance failures
- Possible to test the actuator with any fixed signal under a test mode
- Wide operating temperature range -30 ~ +80℃
- Low air consumption

Option

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