The Koyo DirectLOGIC 405 D4-450 is a highly capable central processing unit module engineered for high-demand industrial automation environments. As part of the modular DL405 platform, this CPU handles robust local, expansion, and remote I/O configurations seamlessly. It eliminates complex networking hardware by offering four independent communication channels that support K-sequence, DirectNET, Modbus RTU, and ASCII protocols simultaneously.
Designed for long-term operational longevity, the front-access panel reveals terminal strip connections alongside a plug-in Lithium backup battery to ensure user ladder programs and system data registers are safely preserved during power interruptions. Whether you are executing sophisticated floating-point arithmetic or running complex loop logic, the D4-450 brings dependable control architecture directly onto your factory floor.
- High-Capacity Processing Engine: Features up to 30.8K words of total memory (7.5K built-in flash ladder memory, expandable up to 15.5K words via external memory cartridges).
- Built-in Power Supply: Operates on universal industrial line voltages (110/220 VAC select) with built-in terminals and an integrated 24VDC auxiliary output.
- Versatile Quad Ports: Equipped with 4 logical communication interfaces including a 15-pin RS-232 programming port, a 6-pin RJ12 port, and a 25-pin RS-232/422/485 expansion interface.
- Advanced Process Control: Supports execution for up to 16 native PID loops, floating-point math processing, and drum sequencing instructions.
- Secure Operation Key: Includes a front-mounted mechanical 3-position mode keyswitch (RUN, TERM, STOP) for physical security and protocol protection on site.
