Relay module Optocoupler isolation 1 relay 5V (537)

Detail Relay module Optocoupler isolation 1 relay 5V (537)

The module uses a fully isolated design, high and low level can be triggered, compatible with many interfaces, suitable for single-chip control, equipment control, household appliances, security equipment.

1. Interface description:
1. V+ is the positive terminal of the relay's working voltage of 5V;
2. GND is the ground, connected to the negative terminal of the 5V power supply;
3. Two INs are signal input terminals, both high and low level, both positive and negative can be triggered, the signal source cannot be connected to V+ and GND;
4. NC, which is normally closed, the relay is short-connected with COM before being pulled in, and disconnected after being pulled in;
5. COM, as the switching terminal (action terminal), as a public interface
6. ON, which is the normally open end, the relay is disconnected from COM before being pulled in, and connected to COM after being pulled in;
2. Electrical parameters:
1. The working voltage of the relay is 5V;
2. Dimensions (length, width and height): 52mm X 26mm X 20mm
3. Relay load capacity: AC (alternating current) 250V/10A, DC (direct current) 30V/10A;
4. Trigger level: trigger voltage 2.5V~5V, trigger current 5mA;
5. Indicator light, the red LED light is the power indicator light, the module will light up when the module is powered on, and the green LED light is the relay pull-in indicator light, when it is off, it lights up;
