SEL-2440
DPAC Discrete Programmable Automation Controller
- The SEL-2440 is a compact Discrete Programmable Automation Controller (DPAC) that combines powerful I/O performance with advanced logic capabilities. Designed for the control and monitoring of equipment in substations and industrial sites, it features microsecond-level time-stamping and rapid processing speeds. It is an ideal solution for distributed I/O systems or auxiliary control applications.
Key Features
-
High-Speed I/O Processing
Features a fast 2 ms logic processing interval, delivering an impressive response time of approximately 7 ms from input detection to output operation. -
Flexible I/O Configuration
Provides a total of 48 digital I/O points with three hardware options to suit specific user needs: 32 inputs/16 outputs, 16 inputs/32 outputs, or 48 inputs/0 outputs. -
Precise Time-Stamping
Records all events with microsecond precision and allows output control to be synchronized to IRIG-B, PTP, SNTP, or DNP time sources. -
Advanced Automation Logic
Includes 32 logic variables, timers, counters, latches, and math functions, allowing for the programming of complex automation scenarios. -
Strong Security and Communications
Seamlessly integrates with existing systems by supporting DNP3 (Serial/Ethernet), Modbus (RTU/TCP), IEC 61850, and SEL’s proprietary MIRRORED BITS communications. -
High Reliability
Ensures stable operation in harsh environments through continuous self-diagnostics and optional conformal coating for protection against contaminants.
Convenience features
-
Removable Terminal Blocks
Features terminal blocks that can be removed while the wiring remains connected, making installation, maintenance, and device replacement quick and efficient. -
Status Indication LEDs
Equipped with individual LEDs for every I/O point and communication port, allowing field personnel to instantly verify the device's status and I/O activity. -
Front Management Port
A dedicated management port on the front panel allows for convenient connection to a laptop for device configuration and diagnostics in the field. -
Easy Hardware Configuration
Protocol and communication addresses can be set via switches located behind the front panel, enabling the device to be used as a distributed I/O unit immediately without additional software. -
Versatile Mounting Options
The compact 2U design supports various installation methods, including rack-mount, panel-mount, and surface-mount, to fit any field requirement.
