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.

- All connectors have positive retention, so wires and cables cannot pull off
- Digital outputs rated for utility grade per IEEE C37.90, eliminating the need for interposing relays.
- I/O labels match status LEDs. 48 status LEDs, one for every I/O point
- All outputs are rated for utility grade per IEEE C37.90, eliminating the need for interposing relays
- Standard 10/100BASE-T Ethernet ports with integrated switch eliminate the need for an external switch
- All digital inputs are rated for ac and dc and time-stamped to 1 μs accuracy
- Two standard EIA-232 serial ports, with EIA-485 and fiber options available for one serial port
- All input thresholds are near ½ nominal voltage to avoid false assertions during faults and battery grounds
- Demodulated IRIG-B input synchronizes the microsecond timer to absolute time and drives the demodulated IRIG-B output
- Alarm contact alerts you to self-test failure, communications access, and settings changes
- Wide-range universal power source, 19.2—275 Vdc, and 19.2—264 Vac
