Two new feature-enhanced DL405 PLC CPUs have been added, the D4-454 and D4-454DC-1. The D4-454 CPUs ($859.00 ) provide all the capabilities of the D4-430, D4-440 and D4-450 CPUs, using updated microprocessor technology allowing the D4-454 to be the CPU of choice for the DL405 family. Both D4-454 CPUs include a built-in power supply and four communication ports. Each CPU offers a large amount of program memory, advanced diagnostics and a substantial instruction set that includes drum sequencers, ASCII output, floating point math, trig functions, bit of word manipulation, timed and hardware-triggered subroutines, For/Next loops, fill-in-the-blank PID control, and more. The DirectLOGIC DL405 controller offers reliable, time-tested hardware with a wide variety of I/O modules, configurations and many specialty modules available.
