SMARTLINK® DS Intelligent Control Actuator Series

The SMARTLINK® DuraStep (DS) provides highly accurate positioning, with continuous duty, maintenance-free operation. The SMARTLINK® DS offers many advantages and flexible feature configurations, making it well-suited for a myriad of industrial applications. It is a general purpose control actuator designed for the precise control of air, fuel, gas, steam, chemicals and liquids for industrial combustion applications, as well as for general industrial process control applications. Simple wiring; standard communications protocols include analog 4-20 mA or Modbus which enables a wide range of positioning and health reporting capabilities. Diverse application needs can be easily met by selecting from a number of product options: two torque offerings, local user display, AC or DC power input, hazardous location approvals. All models provide highly reliable, precise and repeatable operation with continuous modulation. Available configurations include actuator only (DSSA), actuator with valve mounting bracket (DSCA), actuator coupled with a butterfly valve (DSCV), actuator coupled with a ball valve (DSBV) or mounted on a selection of Maxon burners.

Features & Benefits:

• The SMARTLINK® DS offers many advantages and flexible feature configurations making it well suited for a myriad of industrial applications. It is a general purpose control actuator designed for the precise control of air, fuel, gas, steam, chemicals and liquids for industrial combustion applications, as well as for general industrial process control applications
• Standard torque options are either 300 in-lb (33.9 N.m) or 900 in-lb (101.7 N.m) actuator
• Optional upgrades of 2-line back-lit LCD display, AC or DC power, brake, and hazardous location rating
• Valve commissioning accomplished with simple to understand graphical user interface via on-board LCD display, via commissioning PC software or via DCS direct programming
• The electronic shaft brake provides the capability to limit shaft movement of the actuator in the event of a loss of AC or DC power input to the actuator or if the rated torque capability of the actuator is exceeded
• Optional hazardous location ratings are available and the standard general purpose NEMA 4x offering is rated for wash-down/exterior applications and performs under a wide temperature range, making it well suited for the most extreme installations
• Available as stand-alone unit or direct coupled with MAXON’s line of butterfly and ball valves. Also separate linkages and couplings are available to support integration to other valves
• Wide range of butterfly and ball valve body connections and body materials of construction: cast iron, carbon steel, brass, stainless steel as well as internal trim seal sets compatible with oxygen, natural gas, propane gas, digester gas, butane gas, coke oven gas, manufactured gas, landfill gas and a wide range of chemical compatibilities
• Industry standard communications protocols; analog 4-20 mA and Modbus digital for input and output of valve position confirmation as well as valve status, diagnostics, historical performance, and health reporting
• Built-in, on-line diagnostics to continuously assess the health and performance of the actuator. Alarm and lockout detection algorithms are performed every 50 milliseconds. Any alarm or lockout event that occurs can be externally detected by monitoring an alarm relay contact or viewing the local display at about a 1 second sampling interval
• Simple to install, wire and configure with AC and DC power input options and dual NPT conduit ports for separate power and low voltage control wiring
• Rugged, small footprint extruded and cast aluminum housing with impact, UV and chemical resistant powder coating. Flexible industrial design for reliable, long-life operation and mounting in any orientation
• The permanently lubricated planetary gears are precision machined from hardened alloy steels minimizing any slip or hysteresis providing efficient, smooth, quiet, and controlled positioning. This precise mechanism enables continuous rotation of valves to positions within +/-0.1° accuracy and 1000 positions over a full 100 degrees of rotation with a long service life of over 100 million re-positions
• Operates with a temperature range of -40°C to +70°C (-40°F to +158°F) enabling the units to operate in a wide variety of installations and regions. Actuators have on-board temperature sensors to monitor internal operating temperatures preventing overheating of the actuator and tracking and reporting temperature alarms
• Option available for direct coupling to several popular MAXON burner products, providing fully integrated burner and actuator configuration for easy installation and operation
