Exlar EXP-24 ATEX-rated valve positioner

The Exlar 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 while complying with both ATEX (Directive 94/9/EC) and CSA regulations for explosion-proof applications.

Housed in a robust, IP66-rated enclosure, the EXP-24 positioner integrates a 24 VDC motion controller and brushless servomotor amplifier, and is able to power most resolver feedback brushless motors. With an operating temperature range of -29 to 82°C, the EXP-24 is suitable 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 a wide range of motion control applications.

Designed for analog control, the EXP-24 also includes an isolated RS485 Modbus serial interface for 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 multichannel oscilloscope and data logger.

Set-up of the EXP-24 is accomplished via Windows-based software. The software provides users of the EXP-24 with the means to 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.
