Positioner Controls Linear and Rotary Actuators

March 4, 2011
Exlar announces that conforming to both ATEX (Directive 94/9/EC) and CSA regulations for explosion-proof applications, the EXP-24 Positioner can be used to control most of Exlar’s three-phase linear and rotary actuators, including the EL100 linear and ER115 rotary actuators.
Housed in a robust, IP66-rated enclosure, the Exlar EXP-24 Positioner integrates a fully featured 24VDC motion controller and brushless servo motor amplifier, and is able to power most resolver feedback brushless motors on the market. With an operating temperature range of -29 to 82°C, the EXP-24 is ideal for process control applications and provides the functionality to position a valve or damper by following an analog input signal and providing position feedback via an analog output. For other applications, additional motion modes are also available to accommodate the widest possible range of motion control applications.Designed for analog control, the EXP-24 also includes an isolated RS485 Modbus serial interface for easy integration into factory-wide process systems. Several diagnostics features are available including real time monitoring, following error, position error, input and output status, communication diagnostics, a multi-channel oscilloscope and data logger.Set-up of the EXP-24 is accomplished via user-friendly Windows® based software. The software provides users of the EXP-24 with the means to simply select all aspects of configuration and control required for operation. Tabbed pages that provide access to input all of the parameters necessary for configuration of valve control or general motion control applications further facilitate ease of set-up.The explosion-proof rating, high performance and robust packaging of the EXP-24 make the positioner ideally suited to a wide range of applications, including:  Valve and damper control   Shipboard fuel management systems   Fuel skids   Oil wells and platforms   Engine test stands   Paint booths   Printing presses Exlar Corporation - www.exlar.com
