Name : 5V One Channel Relay Module Relay Switch with OPTO Isolation High Low Level Trigger Compatible with Arduino

Net Quantity (N) : 1

New 1 way 5V relay module low level trigger relay expansion board electronic control module Product information : product description: 1. This module complies with international safety standards, and the control area and the load area have isolation slots; 2, the use of double-sided FR-4 circuit board design, high-end patch production; 3, using Songle genuine relay control; 4, with power and relay action instructions, the light is bright, disconnected and not bright; 5. When the signal input terminal has a low level signal, the common terminal and the normally open terminal will be turned on; 6, the relay can directly control various equipment and load; 7, there is 1 normally open and 1 normally closed contact; 8. The blue KF301 terminal is more convenient to connect to the control line. 9, module size: 43x17x18.5mm; net weight: 15g Module interface: Input section: VCC: Connect 5V power supply positive (powered by relay voltage) GND: Connect the negative pole of 5V power supply IN: Relay module signal trigger terminal (low level trigger is valid) High and low meaning: The high level trigger refers to a trigger mode that uses the positive voltage of the VCC terminal to connect with the trigger terminal. When the trigger terminal has a positive voltage or reaches the trigger voltage, the relay pulls in. Low-level triggering refers to a trigger method that uses the negative voltage
