Siemens SB 1222 4DQ Signal Board – 6ES7222-1BD30 0XB0
Digital expansion modules provide the option for using further digital inputs/outputs in addition to the existing integral digital inputs/outputs.
This provides users with the following advantages:
- Optimal adaptation:
- with signal modules which can be mixed as desired, users can adapt their controllers exactly to the relevant task. This avoids superfluous investments. Modules with 8, 16, and 32 input/output channels are available
- signal boards can be used where space is limited or if only a few additional inputs/outputs are required. Each Siemens S7 1200 CPU can be modularly expanded by a signal board. This does not increase the mounting space required for the controller
- Flexibility:
If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple
Design
Signal modules
The signal modules have the same design features as the basic devices:
- Installation on DIN rails:
The modules are snapped onto the rail next to the CPU on the right and are electrically and mechanically connected to each other and to the CPU by the integral slide mechanism - Direct installation:
Horizontal or vertical mounting on DIN rail or direct mounting in the cabinet using integral drill holes - All digital modules are easy to replace thanks to removable connecting terminals (“independent wiring”)
Signal boards
The signal board siemens are plugged directly into the receptacle on the front of each Siemens S71200 PLC.
- Mounting:
Signal boards are plugged directly into the SIMATIC S71200 CPU and are thus electrically and mechanically connected to the CPU - The CPU mounting dimensions remain unchanged
- All signal boards are easy to replace thanks to removable connecting terminals (“independent wiring”)
