K3 Pro外部输出端口使用说明书
K3 PRO External Output Signal User Guide
1.概述K3 Pro在机器上面预留了一个信号输出的端口，使用随机赠送的DC插头，根据实际需求
连 接好电路，即可实现包括但不限于自动门禁、流量统计等应用功能。

K3 Pro provides SI and S2 signal output modes. This section introduces common wiring examples in SI
and S2 mode. This article does not make any guarantees for the circuit, only for design reference. Users
need to modify according to their actual use.

注意：因输出电流有限，用户需根据负教功率需求自行设计驱动电路；当接感性应考虑感性/容性负载对电路的影响。 /容性负载 时，
Note: Due to the limited output current, users need to design the drive circuit according to the load
power requirements. When inductive/capacitive loads are connected, the influence of
inductive/capacitive loads on the circuit should be considered.
