About this item
The 4-channel relay module has an operating voltage of 5V, 12V and 24V. | Each path of the module can be triggered by a high or low level by a jumper setting. | The relay module is isolated by a chip-type optocoupler, which has strong driving capability and stable performance. The trigger current is 5mA. | Fault-tolerant design, the relay will not move even if the control line is disconnected. | The low level triggers the relay module's power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided.
