DirectLOGIC (Micro to Small, Brick & Modular PLCs)
Category Selection
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.
- The DL05 micro-brick PLC is the smallest member of the DirectLOGIC PLC family with six built-in I/O combinations of AC, DC, and relay I/O
- The DL06 micro/modular PLC combines a set of fixed I/O with four option card slots for discrete, analog, and communication expansion modules
- The DL205 modular PLC is a versatile rack-based solution that works with a mix of various I/O and communication modules
- The DirectLOGIC DL305 PLC series is a modular PLC that has been in use for over 30 years; a limited number of DL305 components are available
- The DL405 modular PLC is a time-tested platform with a choice of high-density standard and specialty I/O modules (up to 64 points per module)
DirectLOGIC PLCs are not intended for new system development, please consider our latest lines of controllers (Do-more, Productivity, and CLICK) for new installations.

PLCs & CPUs
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.
Expansion I/O
DirectLOGIC 205 and 405 series expansion I/O controller modules allow extra racks of I/O to be added to the local PLC.
Remote I/O
DirectLOGIC 205 and 405 series remote I/O modules allow I/O to be located a great distance away from the local CPU. Remote I/O is ideal for segmented systems controlled by one main PLC or whenever it's more practical to mount the I/O near the machine being controlled.
Bases
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.
DC I/O
DC I/O modules monitor ON/OFF signals or control devices that switch DC power and are available in input, output, or combination input/output models with up to 64 points (depending on series).
AC I/O
AC I/O modules monitor and control ON/OFF type devices that operate with AC power (120VAC, 240VAC, etc.) and are available in input or output models with up to 16 points.
Relay Outputs
Relay modules can be used to operate higher current DC or AC rated devices and are available with up to 16 Form C (normally open/normally closed) and/or Form A (normally open) relay contacts.
Analog I/O
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.
Communications & Networking
DirectLOGIC CPUs offer several built-in communication options. For systems with communication needs greater than what the CPU provides, optional networking modules are available. Serial converters are also offered for any needed serial protocol conversions.
Motion & Specialty Modules
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.
ZIPLink Wiring Solutions
The ZIPLink connection module and cable system eliminates the normally tedious process of wiring programmable controller I/O to terminal blocks. ZIPLink modules are available for most DirectLOGIC series I/O modules.
DirectLOGIC PLC Accessories
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 USB drive if needed.
