Description
This 2-channel 5V relay interface module allows low-voltage microcontrollers to safely switch high-current electrical loads and appliances. Featuring opto-isolated inputs along with normally open and normally closed contacts, it protects your control circuitry while driving demanding equipment. It is well suited for students, hobbyists, and makers building automation or robotics projects.
High-current switching
Each channel is equipped with a high-current relay capable of handling loads up to 250V AC at 10A or 30V DC at 10A. The board provides both normally open (N/O) and normally closed (N/C) contacts to accommodate various circuit configurations.
Microcontroller control
The board features a standard interface requiring 15mA to 20mA driver current per channel. It can be driven directly by TTL logic and platforms including Arduino, AVR, PIC, ARM, 8051, DSP, and MSP430 microcontrollers.
Opto-isolated input protection
Opto-isolated inputs provide galvanic isolation between your sensitive control board and the relay switching stage, safeguarding your logic circuitry from electrical noise.
