DirectLOGIC series PLCs are available in brick, modular, and rack-based models with a common programming platform. Not intended for new system development, the DirectLOGIC controllers have a large installed base that will continue to be served while components are still available.
DirectLOGIC programmable logic controller products range from micro-sized fixed I/O units to modular systems with thousands of I/O. From simple machine sequencing to complex process control, these controllers have been used in countless industrial applications for decades.
DirectLOGIC PLCs are not intended for new system development, please consider our latest lines of controllers (Do-more, Productivity, and CLICK) for new installations.

DirectLOGIC CPUs provide the logic processing, I/O interface, and memory storage required for automated control. CPUs are available as PLC units that include a set of built-in I/O and one or more expansion slots, or in a rack-based configuration requiring a separate base unit and modular I/O. Power is supplied to the CPU and I/O modules from the power supply built into the CPU/PLC unit or from the power supply that is included within the base chassis. Various built-in and expandable serial and Ethernet communication options are offered with these CPUs/PLCs.
PLC base units provide a means of housing and connecting installed I/O. Modular base units supply slots for interchangeable I/O connections to the backplane's data bus. DirectLOGIC 205 and 405 series base units are available with various slot configurations; the power supply is included with DL205 base units.
Analog input, output, and input/output modules monitor and control pressure, temperature, flow, level, and other process signals. Modules are available in high-resolution current, voltage, combination voltage/current, and sensor-specific temperature models with support for a wide range of signals.
Motion and specialty modules are designed to perform specific functions including input simulation and high-speed counting. High-speed inputs and outputs with up to a 250kHz switching frequency can be added with high-speed expansion modules. Simulator modules (for select DL series) provide a set of toggle switches for manually controlled testing and operations.
Accessories for DirectLOGIC PLCs include I/O module terminal blocks, replacement batteries, programming cables, and DL06 LCD display modules. The DirectSOFT programming software is used for all DirectLOGIC controllers. A limited, demo version (PC-DS100) can be downloaded free of charge; the full-featured version can be purchased as a download or on a CD if needed.
