Relay Module, 8 Channels Optocoupler Module Board With Isolation, Support High And Low Level Triggering red board(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. This Relay Module Adopt patch photocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA. The low level triggers the relay module's power indicator (green) and the 8-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. Fault-tolerant design, the relay will not move even if the control line is disconnected.
