12V 2-Channel Relay Module With Optocoupler High Low Level Triggered

Description

• Maximum load:AC 250V/10A, DC30V/10A
• SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
• the module voltage 5V
• each channel module can be set high or low triggered by jumper
• fault-tolerant design, even if the control line is broken, the relay will not operate
• power indicator (green), 2 relay state indicator (red)
• interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
