$40.5
$66.02
1. 5V relay contact capacity 10A 250V with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low. 2. Can be used as a microcontroller development board, can be used as home appliance control, can also be used as PLC expansion output. Instructions: 1. The power supply should meet the scope of use, DC 5V. 2. The power supply cannot be reversed. 3. The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon. 4. The load power should have a certain margin for the relay load. Avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life. SKU: 0264 Categories: Electronic Componets, Relay Module Tag: SHN
