Abstract: A device for controlling an actuator includes a controller mounted within a housing having an outer surface. The controller is adapted for controlling outputs connected to the actuator for controlling an operation of the actuator. A data input interface receives data from the actuator and/or from other equipment being acted on by the actuator. A memory stores expected parameters of the actuator. An operator interface provided on the housing's outer surface accepts operator commands and/or settings for input to the controller. A display and/or indicator on the housing's outer surface displays an output of the controller. The controller compares the data, and/or derived parameters of the data, with the expected parameters, to monitor a health and status of one or both of the actuator and the other equipment. The controller indicates the health and the status to the operator utilizing the display and/or indicator.

Abstract: A deterministic controller for an actuator includes, for example, adaptation for installation in an explosion-proof housing and a primary controller sealed within the housing for controlling outputs. A backup controller is optionally provided for alternatively controlling the outputs. An operator interface is provided on the housing for accepting operator inputs for providing to the controller. A display is provided on the housing for displaying an output of the controller. The controller includes means for monitoring for a failure of the primary controller if the optional backup controller is installed, and the controller is adapted for switching from the primary controller to the backup controller upon detecting the failure of the primary controller. The outputs can be user configured to desired output ranges from the operator interface without opening the housing.
