The EC-PC502-00 programmable expansion card can replace some micro PLC applications. It
adopts the global mainstream development environment PLC, supporting the instruction language
(IL), ladder diagram (LD), and sequential function chart (SFC). It provides a user program storage
space of 16K steps and data storage space of 8K words, and supports saving data of 1K words at
power failure, which facilitate customers' secondary development and meets the customization
requirements.
The EC-PC502-00 programmable expansion card provides six digital inputs, 2 relay outputs, 1 analog
input, 1 analog output, 1 RS485 communication channel (supports master/slave switchover). It is
user-friendly, providing relay outputs through European-style screw terminals and other inputs and
outputs through spring terminals.
