HUAREW 5V 1-Channel Relay Module with Optocoupler Isolation Supports High and Low Level Triggering (Pack of 10)
Specifications: Material: PCB Control signal: TTL Trigger current: 5mA Operating voltage: 5V Maximum load: AC 250V/10A, DC 30V/10A maximum. Switching voltage: 250VAC, 30V Trigger voltage: 0-1.5V (LOW); 3-5V (HIGH) LED indicators: Power indicator: Green Relay status indicator: Red Relay output: 1. NO: The relay is normally open, the relay is suspended before it is closed, and it is shorted to COM after it is closed . 2. COM: Common relay interface 3. NC: The relay is a normally closed interface, the relay is short-circuited with COM before pull-in and left in the air after pull-in. Package includes: 10 x 1 channel 5V relay module with optocoupler.
Product Features
- Convenience:The relay board is with 1 interface, humanized design, input and output terminals and convenient wiring.
- With indicator light: With power supply and working double indicator lights. Power indicator (green), relay status indicator (red)
- Isolation design: The relay board is isolated with a patch optocoupler, and the isolation circuit prevents the relay switching current from damaging the I/O port.
- High quality: The module uses a normally open interface, a high quality relay, the maximum load of the relay module: AC 250V/10A, DC 30V/10A.
- Wide range of applications: Suitable for all types of single-chip microcomputers and can be used in various occasions for power control.
