X series PLC supports BD board expansion function, supports up to 2 BD boards, and can be flexibly configured according to requirements to meet on-site application requirements when the additional demand for digital or analog points of the machine is not large.


①Small size. Compared with the previously thought expansion module, the BD expansion board is only 1/10 of the expansion module.

② Flexible combination. It can support 2 BD boards at the same time. There are various types of expansion boards and can be mixed and matched with each other, and can be combined flexibly according to needs.

③High cost performance. Flexible points can make the products configured by customers more full, avoid unnecessary waste of points, and be more economical in cost

④Easy to install. X series PLC body comes with BD board slot, plug and play, more convenient and beautiful

⑤Exquisite appearance, BD board can be organically integrated with X series PLC, the overall structure is more compact, flat and refreshing
