SB 1223 được thiết kế với
The signal boards are plugged directly into the receptacle on the front of each S7-1200 CPU.
- Mounting: Signal boards are plugged directly into the SIMATIC S7-1200 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")
Chức năng của SB 1223
The SB 1223 digital input/output signal board converts
- the level of the external digital signals from the process into the internal signal level of the S7-1200 controller and
- the internal signal level of the SIMATIC S7-1200 Controller into the external signal level required for the process.
