Applications

Substation Automation—Take advantage of fast I/O, programmable logic, flexible communications, and SCADA integration.

I/O Annunciation—Indicate I/O status for each input and output. Simplify commissioning and troubleshooting with device status and port activity indicators.

Sequential Events Recorder—Store and analyze input state changes with microsecond accuracy. Combine SER data from multiple DPACs to create a system-wide log.

System Control—Perform high-speed control and data acquisition; protect and monitor motors; and replace remote terminal units (RTUs), programmable logic controllers (PLCs), and other controllers.

Bay Control—Integrate bay control for breaker and disconnect switches with full automation, protection, and self-checking functions.

System Automation—Communicate with DNP3, Modbus, LAN/WAN, IEC 61850, and other protocols over Ethernet and serial connections.

Protection Logic Processing—Connect up to 32 inputs and 16 outputs. Program each input with any desired element. Assign the output to trip logic, transfer trip communications, or other control scheme logic.
