10 I/Os Relay Module - CPU Arduino Nano (Relay Output)
Arduino Nano-based industrial relay module with 10 I/Os for monitoring, control, and automation. Relay output variant of the DFR0898; choose this when direct load switching is needed rather than isolated signal outputs.
Pinout
- Power input +
12-24V DC board power input, from DFRobot product specification “Power Input: 12-24V DC” and “Operating Voltage Range: 11.4~25.4V DC”.
