5V继电器模块 KY-019 1路继电器模块 扩展板
(详情提供中英文描述)
中文描述:
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,最合理驱动电路设计,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。
