SS2R-WN2NOH4R
Series SS2 – Smart Positioner
SS2 – Smart Positioner
General Purpose
Intrinsically Safe
Moniteur’s SS2 Smart Positioner has been designed to excel in the harsh working conditions found in the toughest environments. Compared with other smart positioners, the SS2 is easier to calibrate and program, is more resistant to dirty air and has the lowest cost of ownership.
The SS2 has a wide range of communication options including HART, Profibus and Foundation Fieldbus. It also carries ATEX and IECEx certification for Intrinsically Safe. For severly corrosive environments a stainless steel enclosure is available. Check out the long list of features:

Intrinsically Safe Type (IECEx / ATEX / KC Ex ia IIC T5)
Features & Benefits of SS2 Smart Positioner
• Easy and quick auto-calibration
• Detecting RA(reverse acting) or DA(direct acting) automatically
• Available for single or double acting actuators without any special adjustments
• Compact design allowing it 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 termperature range -30°C ~ +80°C
• Improved control of high-friction globe and ball valves by eliminating overshoot and 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
