Giới thiệu

Bảo trì dễ dàng

Bộ điều phối mạng dòng NA-4020/4021 có thể được mở rộng bằng cách thêm tối đa 32 module I/O. Nó có thể cung cấp loại lò xo, khối thiết bị đầu cuối có thể tháo rời (RTBs) cho phép bạn duy trì hệ thống dây trước khi thay thế một module mở rộng  I/O. Mỗi module mở rộng I/O có thể được thay thế dễ dàng và nhanh chóng.
