6ES7221-1BF32-0XB0 - Digital Input Module - SIEMENS
This 6ES7221-1BF32-0XB0 and SIEMENS reference digital input module is a 8 input module for the SIMATIC S7-1200 range.
SIMATIC S7-1200, Digital input SM 1221, 8 DI, 24 V DC, Sink/Source
This SIEMENS module is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
Overview
- Digital inputs / outputs in addition to the integrated I / O of SIMATIC S7-1200 CPUs
- Separate input / output modules;
Can be used with all SIMATIC S7-1200 CPUs except CPU 1211C.
- Signal Boards as plug-in cards on the CPU in case of space constraints; can be used with all SIMATIC S7 1200 CPUs
- For flexible adaptation of the PLC to the task in question
- For subsequent expansion of the system with additional inputs and outputs
Application domain
Digital expansion modules offer the possibility of using additional digital inputs / outputs, in addition to the existing digital inputs / outputs.
The user benefits from this:
- Optimal adaptation:
. thanks to freely combinable input / output modules, the user can adapt his PLC with precision to the task in question. This solution avoids unnecessary investments. There are modules with 8, 16 and 32 input / output channels.
. If the available space is limited or if only a small number of additional inputs / outputs are needed, it is possible to use Signal Boards. Each S7-1200 CPU can be modularly expanded by a Signal Board. The mounting space required for the controller remains unchanged.
- Flexibility:
It is possible to re-equip the PLC during a subsequent extension of the application. Updating the user program is extremely easy.
Constitution
Input / output modules
The input / output modules have the same construction characteristics as the basic modules.
- Standard rail mounting:
The modules are snapped onto the rail to the right of the CPU and electrically and mechanically connected to each other and to the CPU by the integrated slide mechanism.
- Direct mounting:
Horizontal or vertical mounting on a standard rail or direct fixing in the cabinet via integrated holes (no flat mounting).
- For all discrete modules, replacement is facilitated by removable terminal blocks (fixed wiring).
Signal Boards
The Signal Boards are plugged directly into the slot on the front of the S7-1200 CPU.
- Assembly:
The Signal Boards are plugged directly into the SIMATIC S7 1200 CPU, which ensures their electrical and mechanical connection to the CPU.
- The installation dimensions of the CPU remain unchanged.
- For all Signal Boards, replacement is facilitated by removable terminal blocks (fixed wiring).
Note
I / O modules cannot be used with the CPU 1211C.
Signal Boards can be used with all SIMATIC S7 1200 CPUs.
