Automation easier and more cost-effective with new PLCs and power supplies

29-05-2024 | L-com | Power

L-com has introduced a new line of open-source Arduino PLCs and power supplies. These products are essential in process control, transportation and traffic systems, food and beverage, and automation for industrial plants, agriculture, buildings and homes.

These PLCs can be programmed using free, open-source Arduino software. Most PLCs from conventional automation companies need proprietary software licensing for programming. However, open-source programming is disrupting the industry by bringing low-cost solutions to automation controls.

PLCs interface with various input devices, such as sensors and switches, to gather information about the system's state. They also connect to output devices such as motors, valves and relays to control the physical processes. The PLCs feature 19, 21, 38, 42 or 58 analog and digital inputs and outputs (I/O). They accept I/O or sensors and power as inputs and deliver outputs to actuators and HMIs based on computer programs (modified C++ language).

The PLCs provide easy network connection via three communication protocols: Ethernet, the standard protocol for LANs; multi-point RS-485, which excels at communication over long distances and in electrically noisy environments; and point-to-point RS-232, a standard for use over shorter distances.

Also, the company supplies three new power supplies that convert power from AC to DC to run PLCs and other devices for use in industrial automation. The three options consist of a 30W power supply with a 12VDC output, 120W with 24VDC, or 220W with 24VDC. They have universal power inputs of 100VAC to 240VAC for the 30W and 120W models and 200VAC to 240VAC for the 240W model.

The power supplies have overvoltage and overcurrent protection and an LED indicator. Each model can be mounted on a standard DIN rail for ease of installation.

"L-com's new Arduino PLCs and power supplies are cost-effective, as you can program them with open-source software," said product line manager Tim Houghton. "They're also user-friendly, can accommodate future expansion with up to 58 ins and outs, and are versatile enough for many uses, from plant automation to traffic systems."
