4 Channel 5V Relay Module 250V 10A Relays for Arduino, Automation & IoT Kits Advanced API for hardware IO5V Relay Module with Optocoupler Low Level Trigger Expansion Board for Arduino 4 channels These relays work great, genuine work horses, with SMD optocoupler isolation, and very stable performance. It can be used as a microcontroller development board module, or as home appliance control. Normally open interface and can be set to high or low triggered by jumper. Maximum load: AC 250V 10A, DC 30V 10A. Trigger current: 50mA Fail safe design, even if the
