Relay Module, 8 Channel Module Board, High Low Trigger With Optocoupler Isolation Supports, for Automation Equipment Control Industrial (24V)

【Stable performance】Electronic Relay adopts patch photocoupler isolation, which provides strong driving ability while ensuring stable performance. Its trigger current is only 5mA, making it energy efficient and cost-effective. 【24V Power supply】Optocoupler Relay Module operating voltage is 24V for choice, each path of the 8 channel optocoupler relay module can be triggered by the high level or low level through a jumper setting. 【Fault-tolerant design】Voltage monitoring relay is designed with a fault-tolerant design which ensures that even if the control line breaks, the relay will not move. This design provides peace of mind in case of unforeseen issues arising which could compromise the performance or reliability of the module. 【Humanized design】Voltage monitoring relay adopts humanized interface design, all interfaces can be directly connected through the terminal lead, four fixing bolt holes are provided. 【Equipped with indicator lights】Voltage monitoring relay comes with a power indicator light (green) and an 8-way relay state indicator light (red). These lights make it simple to monitor the module's performance and ensure that it is operating as expected. With clear visualization of the module's state, you can easily troubleshoot problems as they arise.
