ATOM HUB SwitchD 2-Relay Kit

PRODUCT DETAILS Description ATOM HUB SWITCH D is a two channel relay power control switch designed specifically for compatibility with the ATOM main controller. The "D" in its name stands for "Direct", indicating that the Switch D uses a direct power input connection to the relays. The AC power supply flows directly to the Normally Open (NO) contacts of the two relays, which are controlled by the ATOM to switch on and off. When using Switch D, users only need to connect their electrical loads to the relays, without the need for additional power lines. Compared to traditional relay control solutions, this module provides a simpler and more efficient approach to controlling electrical loads.In addition to powering the relay loads, the input power supply is also passed through a built-in step-down module to provide the ATOM with a 5V/1A DC power supply. To ensure safety of use, the power input circuit has overheating and short-circuit protection. It effectively disconnects the circuit in the event of excessive current or short circuit to prevent damage to components. Switch D incorporates the SP485EE level conversion chip, which provides an RS485 communication interface to support communication with multiple devices. It also has a built-in 9-24V to 5V step-down circuit to meet the power requirements in industrial scenarios and extend the power supply capabilities. A set of HY2.0-4P interfaces is provided for connecting I2C peripherals or general purpose I/O devices. Combined with ATOM's built-in WiFi functionality, the ATOM HUB SWITCH D enables quick setup of remote device switching applications.
