The ChannelGuard is a 4-channel 5V SPDT power relay board designed for applications in home and industrial automation systems. With the ability to switch up to 10 amperes at 250 VAC, this relay module can be controlly via a microcontroller. Its isolated inputs, protected by optocouplers, ensure the safety of delicate control circuitry. The default state of the relays ensures a smooth transition when power is off, making it a reliable component for various control setups. Additionally, the device operates on an Active Low polarity, requiring the control input to be grounded for switching the relay ON.
