1. Overview

YN-AT-SECC-AC is a PLC communication module specially developed by Shenzhen Yineng Technology for European and American standard AC charging pile.

AC pile is upgraded from ordinary pile to PLC communication function with hardware changes are very few. The original AC pile master control board only needs to add a TTL serial port communication interface, while other circuits remain the same. This module is only responsible for the PLC digital communication part of the AC pile.

Connect with the AC master through the needle arrangement mode, and the interface is very simple. The general AC pile YN-AT-SECC-AC module only needs to connect 5V, GND, R3T (TTL level serial port), CP, PE and 6 network pins to the AC control board, and the other can be suspended.

Note: This module does not undertake the task of PWM wave transmission and CP voltage sampling. These functions are still controlled and sampled by the AC pile master control.
