EC: EXP-24 Positioner for explosive areas

Motion control: Exlar ATEX-rated high-temperature hazardous location EXP-24 Positioner can be used to control most three-phase linear and rotary actuators. This is a Control Engineering 2012 Engineers’ Choice finalist.


EXP-24 Positioner for explosive areas. Exlar ATEX-rated high-temperature hazardous location EXP-24 Positioner can be used to control most three-phase linear and rotary actuators. This is a Control Engineering 2012 Engineers’ Choice finalist.The Exlar EXP-24 Positioner conforms to ATEX (Directive 94/9/EC) and CSA regulations for explosion-proof applications, controlling most three-phase linear and rotary actuators. The EXP-24 integrates a fully featured 24 Vdc motion controller and brushless servo motor amplifier, and is able to power most resolver feedback brushless motors on the market.

Housed in a robust, IP66-rated enclosure and delivering an operating temperature range of -29 C 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. The EXP-24 also offers additional motion modes 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 multichannel oscilloscope, and a data logger. With its explosion-proof rating, high performance, and robust packaging, the EXP-24 is ideally suited to a wide range of applications including valve and damper control, oil well and platforms, and engine test stands.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
