Module mở rộng SM 1222

SM 1222 (signal modules) là module mở rộng tín hiệu ngõ ra số (digital output “DO”) cho PLC S7-1200.


Giới thiệu chung về SM 1222

    • Digital 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 outputs

Ứng dụng của SM 1222

Digital output modules permit the 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 1222

The SM 1222 digital output signal modules convert the internal signal level of the SIMATIC S7-1200 Controller into the external signal level required for the process.
