NeoGiga India offers a wide range of Relay Boards (Relay Modules) designed for easy integration with microcontrollers, development boards, and PLC systems. Relay boards act as driver modules that allow low-power signals from Arduino, ESP32, Raspberry Pi, or PLCs to control high-voltage and high-current loads. Available in 1-channel, 2-channel, 4-channel, 8-channel, and 16-channel configurations, these boards feature opto-isolated inputs, screw terminals, status LEDs, and overcurrent protection, ensuring safety and reliability. Applications include IoT automation, robotics, smart home appliances, EV charging stations, CNC machines, and industrial control panels. Popular modules use Songle SRD series, Omron, and Panasonic relays, ensuring long life and stable performance. NeoGiga India ensures genuine quality relay driver boards, with bulk B2B pricing, institutional support, and nationwide express delivery (including 1-hour service in select cities), making it the preferred source for students, makers, OEMs, and industrial engineers.
