Siemens SIMATIC S7-1200 CPU 1211C, 6 DI, 2 AI (0-10 VDC), 3 HSC, 4 saídas de relé, 24V DC, PROFINET, 50 KB de memória 6ES7211-1BE40-0XB0

Compact automation tasks often demand a controller that balances performance, flexibility, and ease of integration without consuming excessive panel space. The Siemens SIMATIC S7-1200 CPU 1211C addresses this need by packing essential control capabilities into a compact, modular PLC that is ideal for small to medium-sized applications.

Who is it for

This CPU is tailored for machine builders, system integrators, and OEMs who require a reliable and cost-effective controller for standalone machines or small production lines. It is particularly suited for applications involving simple motion control, counting, and basic analog processing, such as conveyor systems, packaging machines, and pump control.

Main features

• Integrated I/O: 6 digital inputs (24V DC), 2 analog inputs (0-10V DC), and 4 relay outputs for direct connection to sensors and actuators.
• High-speed counting: 3 high-speed counters (HSC) up to 100 kHz for precise position or frequency measurement.
• PROFINET interface: Built-in RJ45 port supports PROFINET IO Controller/Device, TCP/IP, UDP, ISO-on-TCP, and S7 communication for seamless networking.
• Expandable architecture: Supports up to 2 signal boards and 3 communication modules for added flexibility.
• Integrated real-time clock: Battery-backed for accurate time stamping and scheduling.
