Modicon M251 PLC

Manufacturer: Modicon

Modicon M251 controllers offer an innovative, high-performance solution in the field of modular machines and distributed architectures.

Thanks to their compact dimensions, they can optimize the size of wall-mounted and floor standing control system enclosures.

Since Modicon M251 controllers have no embedded I/O, field devices such as variable speed drives and remote I/O are connected on either the CanOpen bus or the Ethernet network.

The Ethernet ports embedded in each M251 controller offer FTP and web server services, making it easy to integrate control system architectures and remote control of machines using applications for smartphones, tablets and PCs.

Features Applications Model

Both Modicon M251 logic controllers come in an identical format (w x h x d): 54 x 90 x 95 mm (2.13 x 3.54 x 3.74 in).
Modicon M251 controllers have no embedded I/O but can be combined with Modicon TM3 expansion modules.
Each M251 controller has a Run/Stop switch.
Each M251 controller has a slot for an SD (Secure Digital) memory card.
Each M251 controller has a QR code for direct access to its technical documentation.

The wealth of embedded functions minimizes the cost of the machine: Functions embedded in the controller: Modbus serial link, USB port dedicated to programming, CANopen fieldbus for distributed architectures, advanced position control functions (high-speed counters and pulse train outputs for servo motor control).
Functions embedded in the Modicon TM3 expansion: functional safety modules, motor-starter control module and remote expansion system.
Functions embedded in the Modicon TM4 communication modules.
The processing power and the memory size of M251 controllers are ideal for targeting performance applications.
The application is created quickly thanks to the intuitive nature and power of the
SoMachine programming software. It also makes it easy to retrieve existing applications in the Modicon M221, M238 and M258 ranges automatically, maximizing use of the investment already made.
