Siemens CPU 1212C

CPU 1212C, 8DI/6DO/2AI


The CPU 1212C 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.

Siemens SIPLUS S7-1200 CPU 1212C DC/DC/DC RAIL

  • 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
  • 8 integrated digital inputs 24 V DC (current sinking/current sourcing (IEC type 1 current sinking))
  • 6 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)
  • 4 fast counters (3 with max. 100 kHz; 1 with max. 30 kHz), with parameterizable enable and reset inputs, can be used simultaneously as up and down counters with 2 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)
  • Expansion by a wide range of analog and digital input and output signals via signal modules
  • 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)

    • 3 device version - allows for  variation with different Voltage Input and Output
    •  Integrated  power supply - allows for 85 to 264 V AC or 24 V DC input
    •  PWM up to 100KHZ - allows for interface with stepper control systems without  any additional components or increased costs
    • Integrated Ethernet interface - allows for programming with no additional cost for adapters
    • 4 fast counters - Onboard I/O can be configured for fast counters at no additional cost
    • Communications interfaces - no additional costs for adapters,
    • Signal boards I/O - additional I/O can be configured without increasing the footprint of the basic unit
    • Optional memory expansion - memory can be expanded for additional storage capacity if required
    • PID controller with auto-tune - built in fuctions without any additional costs
    • Integrated real time clock - real time clock functionality at no extra cost
    • Interrupt inputs - standard I/O can be configured for  interrupt functions
    • Removable terminals - for quick changeout
    • Counters on-board - onboard I/O can be configured as counters
    • Password protection - Allows for  OEM know-how protection
    • Test and diagnostic functions - treamlines commissioning
    • Force outputs for testing - streamlines commissioning
    • Motion control onboard - Low cost controller with motion control capability
    • Library functions - allows for import of user defined librarys
