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.

  • 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 componets 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 -   streamlines 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
