Programmable Logic Controllers (PLCs) are industrial computers designed to control machinery and processes. They automate tasks by receiving input signals from sensors, processing the data through pre-programmed logic, and sending output signals to control devices like motors, valves, and lights. PLCs are highly reliable and adaptable for continuous operation. They are used in industries such as manufacturing, automotive, energy, food processing, and water treatment to automate processes, improve efficiency, and ensure consistent performance in demanding environments.

TCI Supply offers industrial PLC parts from major automation giants such as Allen Bradley, Siemens, Schneider Electric, GE Fanuc, Omron, Yokogawa, and Mitsubishi.  We offer full rack capability, with products such as processors, ethernet switches, input / output cards, power supplies, PanelView terminals, drives, high-speed counters, and sensors.

Industrial and Commercial PLCs FAQ

Can your PLCs be integrated with existing control systems?

Yes, we have extensive experience integrating new parts with existing systems. Through careful cross-referencing and thorough series checks, we ensure that the components we deliver are not only of the highest quality but also seamlessly compatible with your current network. Our team is dedicated to making sure that any new parts function perfectly alongside your existing materials, maintaining the efficiency and reliability of your operations.

Common integrations include EtherNet/IP, DeviceNet,ControlNet, Modbus, Third-Party, and Studio 5000 software tools.

Do you provide programming support for your PLCs?

For programming and software-related inquiries, we recommend consulting the technical guides or reaching out directly to the manufacturer’s customer support team. They have the specialized knowledge to address your concerns effectively. Our goal is to assist your maintenance team in every way possible, ensuring they have the right resources and guidance to achieve success and maintain optimal performance in your operations.

Are your PLCs suitable for harsh industrial environments?

Allen-Bradley PLCs (Programmable Logic Controllers) are suitable for harsh industrial environments. They are designed and built to endure extreme conditions, including high temperatures, vibration, dust, and moisture.

Some PLCs require additional durability to withstand the test of time in challenging environments. At TCI Supply, we offer various solutions, including explosion-proof housings where applicable, and conformal coating sprays. This polymeric film, typically 25–75 µm thick, shields electronic devices from moisture, dust, chemicals, and mechanical stress by conforming to the circuit board’s topology. By enhancing the reliability and durability of your devices, these coatings can significantly extend their lifespan, even in harsh conditions.

Do you provide the most recent series and date codes, in a factory sealed box?

Yes, TCI Supply provides the most recent and current PLC Series, new and in the original box.  We offer a TCI Supply 1 year warranty.  Most PLC series are backwards compatible so, for example, Series C will work in place of Series B and A but not vice-versa.  If your engineers require a specific legacy series or firmware, please let your sales associate know when quoting and we will try to get your exact specifications delivered.

Can you assist with selecting the right PLC model for specific applications?

Yes, TCI Supply can help to select the correct models for your applications.  We can direct you to online catalog pages, conduct thorough cross-references, or even migrate you to another brand altogether.  Please let us know any application requirements before shipment.
