Schneider Electric Modicon M251 Logic Controller (2x Ethernet)
SKU: CCS-TM251MESE
This Modicon M251 Logic Controller is built for modular and distributed architectures, offering both flexibility and powerful data transfer capabilities for connecting to SCADA, MES, and ERP systems. Its dual Ethernet ports simplify machine integration and allow unlimited remote access for maintenance, including through an embedded web server accessible via standard Ethernet or Wi-Fi.
The PLC is optimized for high-performance applications involving speed and position control. Key features include:
- Powerful CPU: Supports execution times as fast as 0.3 ms per 1 KInstruction.
- Expandable I/O: Supports up to 7 local and 14 remote I/O expansion modules.
- Connectivity: Integrated USB 2.0, non-isolated RS232/RS485 serial link (Modbus RTU/ASCII), and two 10/100BASE-TX Ethernet ports.
- Memory: 64 MB system RAM and 128 MB built-in flash memory for user program backup.
- Programming: Intuitive programming using EcoStruxure Machine Expert (SoMachine).
Housed in a compact form factor (54 mm width) with IP20 protection, the PLC is designed for DIN rail mounting and provides robust resistance to environmental disturbances, making it ideal for car wash control systems.
