Photo and product description
1、输出驱动能力：250VAC-10A、125VAC-10A、30VDC-10A、28VDC-10A；
2、使用方便，每组输出简单3线结构，预留6个输出接线柱；
3、输入直接与单片机IO口或数字电路连接，输入高电平继电器吸合，输入低电平继电器释放；
4、工作电压5V，吸合电流约70mA每路，带继电器状态指示灯；
5、全贴片元件，合理驱动电路设计，采用8050三极管驱动继电器动作；
6、设有固定螺丝孔方便安装，电路板尺寸1.8cm*4.0cm*1.9cm，重15g；
简单测试说明: 模块输入与输出电气绝缘，供上对应正确电压后，只需在输入排针上接上高电平(如与VCC短路)就能让继电器吸合，不接或接低电平(如与GND短路)继电器不动作。
