Programmable logic controllers have to reliably execute the numerous logic operations and communication requests that automated facilities/machines require. The DirectLOGIC 405 controller offers reliable, time-tested hardware with many specialty modules available.
The DirectLOGIC DL405 controller offers two feature-enhanced CPUs in this product line, the D4-454 and D4-454DC-1. Both include a built-in power supply and communication ports. Each CPU offers a large amount of program memory, The D4-454 CPUs offer a substantial instruction set and advanced diagnostics that includes drum sequencers, ASCII output, floating point math, trig functions, bit of word, timed and hardware-triggered subroutines, For/Next loops, Fill in the blank PID control, and more.
The D4-454 CPU with new electronics is a direct replacement for the D4-450 in many ways:
