Feature:1 Self-locking relay module, independently of each other without affecting each other. It can control large loads and current up to 10A. It can control both low voltage circuit and 220V high voltage circuit. This module employs STC single-chip microcomputer as a logic processing core and uses connection sampling to address interference signals that can operate stable in complex interference environments. The module has anti-interference protection.

Max current is tolerant. 1.0V Trigger Current Requirements: 0.1 matrigger Mode: Trigger trigger with rising edge to close the relay once and trigger the relay to open the concept of againtriggering This module is triggered at a short pulse level and requires a high level with a 20ms lasting time. This level is the voltage from the positive pole of the power supply of this module. After trigger, the module remains in its final state, i.e. the trigger signal disappears, and the relay pull in state will not disappear. Working Voltage: This module default shipment is 12V DC. Dry contact. It is equivalent to a switch that is not charged by itself. Can control 5V circuit, 12V circuit, and 220V circuit circuit. This module adopts STC single chip microcomputer as a logic processing core, adopting connection sampling to support interference signals, and can operate stable under the environment. Complex interference. Application: Suitable for low current control high voltage, intermediate relay, AC contactor
