DirectLOGIC DL405 Small Modular PLC

DirectLOGIC 405 Modular Programmable Logic Controller (DL405 PLC)

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 DirectLOGIC D4-450 CPU is updated to a model D4-454 CPU.

The D4-454 CPU with new electronics is a direct replacement for the D4-450 in many ways:

• More memory than the largest memory size available to the D4-450
• Same instruction set
• Support for bases and modules currently available
• Readily available coin style battery, D2-BAT-1
• Port 2 supports Modbus RTU (master/slave)

DL405 PLC controller system features include:

• Three base sizes
• AC/DC in/out, up to 64 points
• 10A relay out
• 12-bit and 16-bit analog inputs and outputs
• Thermocouple and RTD inputs
• Data communications, including serial and Ethernet modules
• High-speed counter input and pulse output
• Serial remote I/O master and slave modules
• Ethernet remote I/O master and slave base controllers
