Input/Output Features Inputs (Status and Alarms) Use digital inputs to monitor critical alarms or status points and time-stamp to the microsecond.

Figure 4 Independent and Isolated Inputs

Figure 5 Bussed Inputs

SEL inputs are designed and tested to ensure they operate correctly for dc battery grounds and capacitive discharges.

The bold line in Figure 6 shows how an earth fault completes the battery path through the input, bypassing the output. If the input is rated for 125 Vdc, the 65 Vdc that the fault causes across the input will assert the input.

SEL level-sensitive inputs are designed so that they do not operate for this condition.

The bold line in Figure 7 shows a discharge path from the wiring capacitance through the input when a knife switch is closed. This discharge can cause a temporary assertion of an input. SEL inputs are designed with debounce timers so that they do not operate for this condition.

Figure 6 Secure Against DC Grounds

Figure 7 Secure Against Capacitive Discharges

Outputs (Relays) Outputs are rated for 30 A make and inductive interrupt applications such as trip and close operations and motor control. See the Output specifications for more details.

Figure 8 Independent and Isolated Outputs

Power The POWER terminals on the rear panel must connect to 120–230 Vac or 24–250 Vdc with the proper polarity.

These terminals are isolated from chassis ground. Extra terminals are provided so power can be daisy-chained from DPAC to DPAC.

IRIG-B

A demodulated IRIG-B input and output are provided so this signal can be daisy-chained between DPAC devices.

Connectors Removable terminal block connectors make installation and replacement quick and efficient but can result in intermittent or lost connections if positive retention means aren’t provided. The following diagram shows one of the pluggable connectors used on the DPAC and points out the retention screws that ensure connections remain in place.

Conformal Coating The optional conformal coating protects the DPAC printed circuit board from moisture and corrosive elements found in harsh installations. This conformal coating option conforms to Mil-1-46058C Type UR conformal coating requirements.

Communications Ports A rich collection of communications ports and protocols are available with the DPAC as shown in the following figure, which also includes connection examples.

Analyze Sequence–of–Events Record sequence-of-events with the Sequential Events Recorder (SER) function. With this function, you can analyze assertions and deassertions of digital inputs and outputs—as many as 512 state changes to the microsecond for as many as 96 different digital points. The function also captures when the device powers up and a settings change occurs.

Combine SER data from individual SEL-2440 DPAC devices into a system-wide log. Synchronize the system with IRIG-B time code and the report data will align perfectly.

Automation Features Flexible Control Logic and Integration Features Eases Configuration The DPAC does not require special communications software. Use any system that emulates a standard termi-nal system for engineering access to the device.

Simplifies Communications The SEL-2440 is equipped with three independently operated serial ports. Establish communication by con-necting computers, modems, protocol converters, print-ers, an SEL Communications Processor, SCADA serial port, and an RTU for local or remote communication.

Apply an SEL communications processor as the hub of a star network, with point-to-point fiber or copper connec-tion between the hub and the SEL-2440.

Supports Standard Protocols As with most SEL devices, the DPAC comes standard with the communications protocols listed below.

➤ DNP3

➤ Modbus

➤ SEL ASCII

➤ SEL Compressed ASCII ➤ SEL Fast Meter ➤ SEL Fast Operate

➤ SEL Fast SER ➤ SEL Fast Message

➤ SEL MIRRORED BITS

Time Synchronization Protocols The DPAC supports the following protocols for synchronizing your device to master clocks.

➤ Demodulated IRIG-B ➤ Firmware based PTP (IEEE 1588-2008) ➤ SNTP from High Priority or Low Priority servers

➤ DNP3

Simplifies SCADA SEL devices provide proprietary but open, binary “fast” protocols. These protocols are self-describing and are interleaved with ASCII protocols on the same port. Sim-plify configuration, minimize communications wiring, and improve performance between the DPAC and other devices (e.g., communications processors) with these protocols.

Performs Logic and Math Eliminate PLCs with Boolean logic, rising/falling edge triggers, and math (+, -, *, /).

Replaces Traditional Latching Relays Replace as many as 32 traditional latching relays for such functions as “remote control enable” with latches.

Program latch set and latch reset conditions with SELOGIC® control equations. Set or reset the nonvolatile latches using optoisolated inputs, Remote Bits, latches, or any programmable logic condition. The latches retain their state when the device loses power.

Eliminates External Timers Eliminate external timers for custom protection or con-trol schemes with 32 general purpose SELOGIC control equation timers. Each timer has independent time-delay pickup and dropout settings. Program each timer input with any desired element. Assign the timer output to trip logic, transfer trip communications, or other control scheme logic.

Eliminates External Counters Eliminate external counters for custom control schemes with 32 counters, updated every 2 ms processing interval.

Each counter element consists of five inputs (preset value; load preset value, count up, count down, and reset to zero) and three outputs (counter value; count as many as preset reached, count down to zero reached).

Eliminates RTU-to-Device Wiring Eliminate RTU-to-Device wiring with 32 Remote Bits.

Set, clear, or pulse Remote Bits using serial or Ethernet port commands. Program the Remote Bits into your con-trol scheme with SELOGIC control equations. Use Remote Bits for SCADA-type control operations such as trip, close, and settings group selection.

Provides Annunciation

Indicators (LEDs) provide annunciation of I/O status for each input and output. In addition, device status and port activity indicators simplify commissioning and troubleshooting.

Type Tests Note: To ensure good EMI and EMC performance, type tests were performed using shielded copper Ethernet cables with the shell grounded at both ends of the cable. Additionally, digital inputs were configured with 4 millisecond pickup and dropout time settings.

Double-shielded cables and 4 millisecond or greater pickup and dropout times are recommended for best EMI and EMC performance.
