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 6 digital inputs, 2 relay outputs, 1
analog input, 1 analog output, and 1 RS485 communication channel (for master/slave
switchover). It is user-friendly, providing relay outputs through European-type screw
terminals and other inputs and outputs through spring terminals.

connected to the control board (the period is 1s, on for 0.5s,
and off for the other 0.5s); and it is off when the expansion
card is disconnected from the control board.
This indicator blinks when an error occurs (the blinking
period is 1s, on for 0.5s, and off for the other 0.5s). You can
(Red) query the error types on the upper computer Auto Station.
