12V 4-Channel Relay Module with Optocoupler Isolation

Product Narrative

12V Relay Module: Working Voltage: DC 12V; Maximum Load: AC 250V/10A, DC 30V/10A; Trigger Current of Optoisolator: 5mA

This 12V relay module is perfect for your projects and applications. It operates on a working voltage of DC 12V and can handle a maximum load of AC 250V/10A or DC 30V/10A. The optoisolator trigger current is only 5mA, ensuring efficient and reliable switching.

Fault-Tolerant Design: Even if the control line breaks, the relay won't operate. All relay interfaces can be directly wired out through the terminals. The module supports normally open (NC) and normally closed (NO) configurations.

Optocoupler Isolation: The 1-channel relay board uses optocoupler isolation, providing strong driving ability and stable performance. The isolation circuit prevents damage to the I/O port from relay switch current.

Jumper Design: This relay module comes with a jumper that allows you to set the unit state easily with high or low signals. It features screw terminals for relay (NC/C/NO), coil (+ and -), and trigger inputs.

Wide Application: This 12V relay module works well with various electronic devices such as ARM, PIC, AVR, MCU, Raspberry Pi, CNC machines, and even PlayStation 4. Its versatility makes it a great addition to your projects.
