CPU 1211C

CPU 1211C, 6DI/4DO/2AI

 

The CPU 1211C compact CPU comes in 3 versions, DC/DC/DC, AC/DC/relay and DC/DC/relay. Profinet is standard with the ability to expand to other protocols like Profibus, AS-Interface and Modbus through additional communications modules. I/O is expandable with a maximum of expansion of 3 communications modules, 1 signal board and 2 signal modules.

  • 3 device versions with different power supply and control voltages.
  • Integrated power supply either as wide-range AC or DC power supply (85 to 264 V AC or 24 V DC)
  • Integrated 24 V encoder/load current supply:
    For direct connection of sensors and encoders. With 300 mA output current also for use as load power supply.
  • 6 integrated digital inputs 24 V DC (current sinking/current sourcing (IEC type 1 current sinking)).
  • 4 integrated digital outputs, either 24 V DC or relay.
  • 2 integrated analog inputs 0 to 10 V.
  • 2 pulse outputs (PTO) with a frequency of up to 100 kHz.
  • Pulse-width modulated outputs (PWM) with a frequency of up to 100 kHz.
  • Integrated Ethernet interface (TCP/IP native, ISO-on-TCP)
  • 3 fast counters (100 kHz), with parameterizable enable and reset inputs, can be used simultaneously as up and down counters with separate inputs or for connecting incremental encoders.
  • Expansion by additional communication interfaces, e.g. RS485 or RS232
  • Expansion by analog or digital signals directly on the CPU via signal board (with retention of CPU mounting dimensions)
  • Optional memory expansion (SIMATIC Memory Card)
  • PID controller with auto-tuning functionality
  • Integral real-time clock
  • Interrupt inputs:
    For extremely fast response to rising or falling edges of process signals.
  • Removable terminals on all modules
  • Simulator (optional):
    For simulating the integrated inputs and for testing the user program.
