The EC 3000 is an embedded controller designed to direct the operation of automated machinery. When programmed with an operating sequence, the microcomputer- based technology of the EC 3000 provides flexible and accurate control of a wide variety of industrial processes. Installation is uncomplicated and easily tailored to different applications. Using the graphical user interface (GUI), the program can easily be configured to meet specific system requirements. The EC 3000 incorporates many selectable features designed to make operation of the controller both easy and accurate. These functions are selected using a menu driven protocol presented on the front panel display.
Provision for process parameter entry and data monitoring are conveniently available through the front panel push-button keyboard. Process data, system status and error messages are shown on the front panel display. The status of the controller, including the state of the eight inputs and sixteen outputs, is indicated either on the display or on annunciation indicators.
Three serial data communication ports are included as standard features. An RS-232 port is available to drive the optional printer. A second RS-232 port is available to drive an optional remote display. An Ethernet port is available to provide computer -compatible data from the factory floor.
This controller design is the latest in a family of products proven in the field through years of production service in the harshest of environments. The single module is surrounded by a steel case enclosure to prevent contamination in hostile environments. All terminations to the controller are made using the interface cable set supplied with the controller. The module is designed to be mounted inside a variety of NEMA style enclosures.
Configurable
The EC 3000 is a general purpose embedded system controller which can be programmed to provide accurate control of industrial processes.
Flexible
Installation and set-up is easily accomplished for a variety of related industrial systems. One control program can be designed to serve the needs of a family of similar processes.
Universal
The EC 3000 has been successfully incorporated into systems manufactured by a wide range of equipment providers. Barrett Engineering can assist with this process.
Reliable
The EC 3000 is reliable in harsh environments. The surrounding enclosure prevents contamination in dirty environments, while the signal filtering design prevents disruption from electrical noise.
Simple to Use
Process parameters are easy to program using the front panel keyboard.
Refer to the specification for details on specific operating features.
