DirectLOGIC DL405 Small Modular PLC

DirectLOGIC 405 Modular Programmable Logic Controller (DL405 PLC)

The DirectLogic DL-405 PLC System

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
