SCHNEIDER ELECTRIC PLC

About SCHNEIDER ELECTRIC PLC

Schneider Electric is a global industrial automation and energy management company headquartered in Rueil-Malmaison, France. The company's Modicon line of programmable logic controllers (PLCs) originated with the Modicon 084, introduced in 1968 as the first commercially successful PLC. Schneider Electric acquired Modicon in 1997 and has since expanded the platform into several families, including the compact M221, the modular M241 and M251, and the distributed TM172 series. These controllers are used for machine control, process sequencing, and building automation across industries such as manufacturing, water treatment, and energy production.

3G Electric supplies Schneider Electric Modicon Series PLCs as part of its industrial equipment catalog. The available models cover a range of I/O configurations and power supply options. For example, the TM172PBG42RI offers 12 analog inputs and 12 digital outputs, or 12 digital inputs and 6 analog outputs, with a real-time clock and serial communication. The TM171ODM22S provides 5 analog and 6 digital I/O channels and operates on 12 to 24V AC or 24V DC. The TM251MESE supports both 24V AC and 24V DC power and includes a built-in clock. Other models such as the TM221CE24T, TM221M32TK, TM221ME32TK, and TM221M16T feature discrete and analog I/O with transistor outputs, operating on 24V AC/DC. These controllers are typically programmed using Schneider Electric's EcoStruxure Control Expert or Machine Expert software, depending on the model.

Technical buyers should note that Modicon PLCs are designed for industrial environments, with specifications that include real-time clocks, serial communication links, and a mix of analog and digital I/O. The M221 series, for instance, is suited for compact automation tasks such as packaging and material handling, while the M241 and M251 offer higher performance for more complex applications. The TM172 series is often used in distributed control architectures. 3G Electric provides global logistics support, datasheets, and quotation services for these products. The company maintains inventory of multiple SKUs and can source additional Modicon models as needed. For engineers and procurement specialists, 3G Electric offers a single point of contact for Modicon PLCs, with the ability to handle orders of varying sizes and ship to locations worldwide.
