DC 2 Channel Relay Module 5V with Optocoupler High or Low Level Trigger Expansion Board for Arduino(5V)
DC 2 Channel Relay Module 5V with Optocoupler High or Low Level Trigger Expansion Board for Arduino(5V)
Product Features
- 2 Channel Isolated Relay Module With Optocoupler , can set high or low level trigger with jumper, to meet the demand of more trigger applications.
- Maximum load: AC 250V/10A, DC 30V/10A.Module voltage:5V
- Using SMT optocoupler isolation, it has strong driving ability and stable performance; trigger current is 5mA; Modules can be triggered by setting high or low levels through wire jumper.
- Easy to install:This 2 Channel Relay Module with Humanized interface design, all interfaces can be directly connected through the terminal lead, which is very convenient.Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides.
- Reliable: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling isolation, triggering more reliable, more stable
