Exlar's EXP-24 positioner can be used to control its EL100 three-phase linear and ER115 rotary actuators. Housed in a robust, IP66-rated enclosure, the positioner integrates a 24-V dc motion controller and servo motor amplifier to power most resolver feedback brushless motors. The EXP-24 positions a valve or damper by following an input signal and provides feedback via analog output. The EXP-24 features an isolated serial interface for integration into process systems; diagnostics including real-time monitoring, position error, I/O status, and communications; an explosion-proof rating; and an operating temperature range of -29 to +82°C (-20 to +180°F). It's suitable for process control applications, and additional motion modes are available for valve and damper control, shipboard fuel-management systems, engine test stands, fuel skids, and oil wells.
