Smart Positioner

CCI brings 40 years of experience and innovation to positioner actuation technology

 

Easy to Use

Flexibility in Installation

High Reliability

Single Model for Multiple Specifications

HART™ Communication

 

Smart Positioner SY Series Smart positioner SY series are microprocessor-equipped, current pneumatic smart valve positioners for pneumatic actuators. The smart positioner receives a DC current signal from control devices and controls pneumatic valves. In addition to this basic function, the SY has communication capabilities, automatic configuration program, and self-diagnostics functions that will greatly increase productivity and the efficiency of plant operation. Calibration, configuration and self-diagnostics can be performed by using a HART™ communicator (or computer via HART™ modem.)

 

Features

 

Easy to Use – Auto Setup

The auto-setup function is a fully-automatic configuration program which specifies the actuator and adjusts the zero and span of the valve. The program can be turned on simply from a switch so that adjustments to the valve can be performed quickly and safely in hazardous areas.

 

Valve Diagnostic

The following parameters can be monitored by HART™ communicator or control valve maintenance support system:

 Stick slip

 Cycle count

 Total stroke

 Shut-off count

 Travel histogram

 Max. travel speed

 

Flexibility in Installation

The SY-1 positioner can be installed to the actuator by using a standardized mounting kit for long linear strokes.

 

High Reliability

 Positive seating: the positive seating function completely shuts off the valve if the input signal becomes lower than previously set. This in turn enhances the full shut-off capabilities of the valves.

 Self-diagnostic: the self-diagnostic function provides the ability to check the status of the positioner at any time and to alert in case of failure.

 

Single Model for Multiple Specifications

The SY settings can be changed without replacing any parts. A single model can be modified to suit any application.

 Flow characteristic: Linear, EQ%, quick opening or custom user characteristics (16 points)

 Actuator type: Double or single acting actuator

 

HART™ Communication

HART™ communicator can be used for calibration, configuration and selfdiagnostics.
