1.3-channel self-locking relay module, independent of each other, without affecting each other. 2.Large load, maximum 10A current can be controlled. 3.Can control both low-voltage circuits and 220V high-voltage circuits. 4.This module adopts STC single-chip microcomputer as the logic processing core, and adopts connection sampling to cope with interference signals, which can work stably under the environment of complicated interference. 5.The module is equipped with anti-interference protection.Item Type:Relay ModuleVoltage: DC 12V (working voltage DC 9.5-15V)Maximum Current the Relay Can Withstand: 10AQuiescent Current: 1.0VTrigger Current Requirement:> 0.1mATrigger Mode: Trigger on rising edge, trigger the relay to close once, and trigger the relay to open againTriggering Concept: This module is triggered with a short pulse level and requires a high level with a duration of 20mS. The level can be externally input or the voltage from the positive pole of the power supply of this module. After the trigger, the module remains in the final state, that is, the trigger signal disappears, and the pull-in state of the relay does not disappear.Working Voltage: The default shipment of this module is 12V DC.The load end is a dry contact, which is equivalent to a switch, which is not charged by itself. It can control 5V circuit, 12V circuit, and 220V circuit.Stability and Reliability: This module adopts STC single-chip microcomputer as the logic processing core, and adopts connection sampling to deal with the interference signal, and can work stably under the environment of complicated interference.Application:Suitable for small current control high voltage, intermediate relay, AC contactor1 x Relay Module
