- Rugged and Reliable
Designed, tested, and manufactured to surpass electrical utility protective relay standards, the SEL-2440 DPAC can handle tough environments. It will operate in extreme temperature ranges of –40° to +85°C, withstand electrostatic discharge up to 15 kV, and handle 15 g shock.
- Fast and Powerful
Get the speed you need with inputs timed to the microsecond and outputs controlled to the millisecond. The 2 ms processing interval keeps the time from input to output at only 7 ms. Internal math and logic allow you to create automation and control systems.
- Great Communicator
Applications require different protocols. The SEL-2440 DPAC includes DNP3, Modbus, Mirrored Bits communications, and SEL Fast Messages; IEC 61850 is optional. Easily connect using the two EIA-232 ports as well as the two RJ-45 Ethernet ports with an integrated switch.
- Easy to Set Up and Maintain
Connect it, set it—Job Done! Pre-programmed register maps, and protocol and address setup via control (DIP) switches make commissioning easy. Connectorized with removable terminal blocks, the SEL-2440 DPAC can be removed from service without lifting a single I/O wire. The positive retention screws keep the connectors from pulling off accidentally. Quickly and easily see the device’s current operating status with LEDs for system status on every I/O point.
