Information About D4-454
The D4-454 is part of the DirectLogic 405 series and functions as the central processing unit within a DL405 PLC rack. It provides 31.5K words of ladder program memory and supports up to 16 interrupt input points for responsive control applications. The module includes multiple communication interfaces, including one RS-232 (DB15), one RS-232 (RJ12), and two configurable RS-232/RS-422 (DB25) ports, enabling flexible integration with peripherals and supervisory systems. Designed for operation in industrial environments, it supports a wide input voltage range and includes a battery for memory retention.
Key Features:
- 31.5K Words Ladder Memory: Supports large and complex control programs.
- Multiple Serial Communication Ports: Includes RS-232 (DB15), RS-232 (RJ12), and dual RS-232/RS-422 (DB25) interfaces.
- DirectLogic 405 Platform: Designed for integration within DL405 PLC systems.
- External 120–240 VAC Power Required: Compatible with industrial AC supply ranges.
- 16 Interrupt Inputs: Enables rapid response to time-critical events.
- Battery-Backed Memory: Maintains program data during power loss.
- Wide Operating Temperature Range: Operates from 32°F to 140°F (0°C to 60°C).
- Rugged Industrial Design: Meets MIL STD 810C vibration resistance standards.
The D4-454 delivers the reliability and precision required for high-capacity PLC control and communication-intensive industrial automation systems.
