12V 4-Channel Optocoupler Relay Board Module

12V 4-Channel Optocoupler Relay Board Module is suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC. The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A. It uses SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA. The power indicator (green) and the relay status indicator (red) are usually indicates the power is available or not and relay is active or inactive. The interface design of human nature, all interfaces are available through a direct connection terminal leads.

Features:

• Suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC.
• Relays are rated up to 10A and have NO/NC contacts. Each channel has an LED indicator to show the relay is on.
• Connects directly to a microcontroller
• LED Indicator for each channel
• Module can be high or low by a jumper setting trigger
• Fault-tolerant design, even if the control line is broken, the relay will not operate
