12V 4-Channel Optocoupler Relay Board Module

The 12V 4-Channel Optocoupler Relay Board Module is designed for switching higher voltages and is compatible with microcontrollers such as Arduino, ARM, AVR, and PIC. It features genuine quality relays with normally open interfaces, each rated up to 10A. The module uses SMD optocoupler isolation for driving ability and stable performance, with a trigger current of 5mA. It includes power and relay status indicators for easy monitoring. The module's interface design allows for easy connection through terminal leads.

  Features:  

• Suitable for switching higher voltages and compatible with microcontrollers.
• Relays are rated up to 10A and have NO/NC contacts.
• LED indicator for each channel to show the relay status.
• Connects directly to a microcontroller.
• The module can be triggered to be high or low by a jumper setting.
• The fault-tolerant design ensures the relay will not operate even if the control line is broken.
