Description

This Arduino Nano I²C relay controller was designed to function as a relay shield for Arduino Nano. This controller consists of one SPDT relay rated at 1 Amp at 120VAC or 1 Amp at 24VDC. The on-board relay is controlled by a MCP23008 using GPIO0. The remaining 7 GPIO pins (GPIO1:7) are available for general purpose TTL/CMOS Input/Output applications under software control. Controlling the on-board relay is easy. Simply set GPIO0 as a Digital Output. Next, set the on/off status of GPIO0 to activate the relays. One LED indicates the status of the on-board relay.

The relay on this controller are rated for low-power signal switching applications, offering an ideal choice for telecommunications, audio, low-power signal, and other resistive or low capacitive load applications. The relays used on this device are Single Pole Double Throw. External devices may be wired to turn on when the relay turns on. Optionally, external devices may be wired to turn off when the relay turns on. This relay should NOT be used in inductive applications (power switching applications involving motors or transformers of any kind).
