5V 2-CHANNEL RELAY BOARDS - 2 x MODULES FOR ARDUINO RASPBERRY Pi ARM AVR DSP PIC

About this deal

This listing includes two 5V 2-channel relay modules, making it a practical buy for makers who want a spare or need to run multiple switching projects at once. Each board is a general-purpose 2-channel relay module for controlling electrical devices via TTL logic, powered from a 5V DC supply. The modules can control appliances and equipment with large current loads, with relays rated to handle AC 250V/10A or DC 30V/10A. Each board provides two relays with screw terminals for both the control side and the load side, supporting Normally Open (NO) and Normally Closed (NC) wiring configurations. Any logic-level signal can be used to activate a relay, making the modules directly compatible with microcontroller TTL outputs. They are well suited to hobbyist and prototyping applications including home automation, lighting, pumps, and motor control, and are compatible with a wide range of platforms including Arduino, Raspberry Pi, AVR, PIC, DSP, and ARM.
