Automationdirect Programmable Controller series, also widely known as CLICK, Productivity3000 and DL06 families, is a complete lineup of industrial PLC solutions designed and manufactured for cost-effective, easy-to-deploy automation projects. Developed by Automationdirect, a US-based industrial automation hardware supplier, this series covers a full spectrum of control scenarios from tiny micro-machine logic control to large-scale distributed industrial systems, eliminating the unnecessary complexity and high cost that often come with traditional mid-to-high end PLC products. Every unit in the lineup is built with industrial-grade hardware components, and paired with fully free, user-friendly programming software that requires no paid license, making it an accessible choice for small engineering teams, hobbyists and large industrial system integrators alike. The entire product range undergoes strict industrial validation to ensure stable long-term operation in factory environments, with full UL, CE and Class 1 Division 2 certifications to meet global industrial safety standards.
The CLICK series, as the entry-level brick-style programmable controller, is designed as a low-cost stackable unit for simple control and monitoring tasks, with standalone variants that can compete with micro-programmable relays on size and price while retaining full PLC expandability. The CLICK analog CPU modules come with built-in 2-channel analog inputs and 2-channel analog outputs, and the supporting free programming software offers 21 practical relay ladder logic and function block instructions, backed by comprehensive built-in online help files. The Productivity3000 series, as the high-end modular rack-based system, supports up to 116,000 I/O points across local, expansion and remote I/O bases, with a high-performance CPU equipped with 50Mb memory, extremely fast scan times and seven industry-leading onboard communication ports. Its P3-550 CPU variant features a 4-line x 10 character LCD screen for direct display of system alarms and user-defined custom messages, with onboard USB, Ethernet and serial device support, a USB plug-and-play connection for programming and online monitoring, a local expansion port that supports up to four additional I/O bases, and a dedicated Ethernet remote I/O port that can connect up to 32 remote base groups. The DL06 micro PLC offers 20 local inputs and 16 local outputs with octal addressing, 229 total instructions covering Boolean operations, advanced math, PID closed-loop control and RLLPLUS stage programming, 14.8K words of program memory split between 7.6K words of ladder logic storage and 7.6K words of V-memory, with Boolean instruction scan speed below 0.6μs and a full 1K program step scan completing in approximately 1 to 2 milliseconds. It also includes two communication ports, with Port 1 supporting fixed 9600bps RS232 communication and Port 2 supporting multi-protocol operation with baud rates adjustable from 300bps to 38400bps, and an operating temperature range of 0 to 55 degrees Celsius with 5% to 95% non-condensing humidity tolerance.
The most standout advantage of Automationdirect programmable controllers is their exceptional cost-effectiveness, with hardware prices far lower than comparable PLC products from major traditional industrial brands, while still delivering full industrial-grade reliability and performance. The supporting programming software is completely free to download and use, with no hidden paid licenses, no subscription fees and no feature lockouts, which drastically cuts down the total project cost for end users. The entire lineup offers highly flexible scalability: the entry-level CLICK series can be expanded step-by-step from a tiny standalone unit to a moderately sized control system, while the Productivity3000 modular system can grow from a small local setup to a large distributed system with tens of thousands of I/O points, adapting to changing project requirements without forcing a full hardware replacement. The hardware design is extremely user-friendly, with clear terminal labeling, DIN rail mounting that requires no special tools, and intuitive programming logic that allows even engineers with limited PLC experience to get a system up and running in a very short time. The full series also offers rich built-in communication features, supporting USB, Ethernet, serial and multiple common industrial protocols natively, eliminating the need for expensive extra communication modules for most standard industrial connection scenarios.
When installing these programmable controllers on a 35mm standard DIN rail, users must maintain the specified minimum mounting spacing: at least 30mm of clearance above and below the units, and no less than 20mm of horizontal clearance between adjacent modules to ensure proper ventilation and prevent overheating during long-term operation. For output terminals without built-in fuses, users must install external fast-blow fuses for overcurrent protection, and for inductive load connections, DC coils must be paired with parallel freewheeling diodes, while AC coils should be equipped with MOV or TVS surge suppression components to protect the PLC output circuits from damage. The default super capacitor for power-down data retention only maintains data for several hours after power loss; if long-term data preservation is required, users must install the optional D2-BAT-1 battery module, which extends retention time to up to 5 years. All wiring should use 16 to 22 AWG gauge wires, with no more than 2 individual wires connected to a single terminal point, and the system must adopt a single-point common grounding scheme with shielded cables grounded at both ends to ensure stable EMC performance. Users must not attempt to modify or flash the controller firmware with unofficial third-party tools, as this will cause permanent firmware corruption and void all product warranty coverage.
Automationdirect programmable controllers are widely deployed in small and medium-sized automated machinery, including conveyor systems, packaging machines, small material handling equipment and standalone production station control. The CLICK series is extremely popular for simple monitoring and automation retrofit projects, where it brings reliable automatic control to older manual machines without requiring a full expensive system overhaul. The high-performance Productivity3000 modular system is used for large distributed industrial control scenarios, including entire production line control, water treatment plant automation, factory material sorting systems and large-scale HVAC building automation setups. The compact DL06 micro PLC is a preferred choice for small embedded control devices, custom test benches and special-purpose industrial equipment where space is limited but full PLC functionality is still required. The entire series is also heavily adopted by educational institutions, hobbyist automation projects and small engineering teams, as its low cost and free software lower the barrier to learning and implementing modern industrial control logic.
