Module mở rộng SM 1223

SM 1223 (signal modules) là module mở rộng tín hiệu ngõ vào/ra số (digital input/output “DI/DO”) cho PLC S7-1200.


Giới thiệu chung về SM 1223

    • Digital inputs and outputs as supplement to the integral I/O of the CPUs
    • For flexible adaptation of the controller to the relevant task
    • For subsequent expansion of the system with additional inputs and outputs

Ứng dụng của SM 1223

Digital input/output modules permit:

    • Connection of the controller to digital signals of the process
    • Output of digital signals from the controller to the process

This provides users with the following advantages:

    • Optimum 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.
    • Flexibility: If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple

Chức năng của SM 1223

The SM 1223 digital input/output signal modules convert:

    • 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.
