The AS28PLC0001 programmable extension card can replace some micro PLC applications. It
adopts the global mainstream development environment PLC, supporting six types of programming
languages, namely the instruction language (IL), structural text (ST), function block diagram (FBD),
ladder diagram (LD), continuous function chart (CFC), and sequential function chart (SFC). It
provides a user program storage space of 128 kB and data storage space of 64 kB, which facilitates
customers' secondary development and meets the customization requirements.
The AS28PLC0001 programmable extension card provides 6 digital inputs, 2 digital outputs, and 2
relay outputs. It is user-friendly, providing relay outputs through European-type screw terminals and
other inputs and outputs through spring terminals.
