Description
Description Atom Switch is a dual-channel programmable switch that supports ATOM, allowing simultaneous control of two AC/DC circuits. It features a built-in step-down module that provides 5V/1A DC power to the ATOM. The onboard relay supports up to 250V/10A mains (16A instantaneous current). To ensure safety, the DC circuit includes overheat and short-circuit protection, effectively disconnecting the circuit in case of excessive current or short-circuit. For industrial applications, we have integrated an SP485EE level conversion chip, providing an RS485 interface for connecting RS485 devices. The RS485 interface can also power the ATOM, supporting a voltage range of 9-24V. Additionally, a HY2.0 interface is provided for connecting I2C peripherals or general I/O devices. Leveraging the ATOM's WIFI capabilities, you can easily achieve remote control of the switch. If you have multiple Atom Switch units, they can be connected in parallel via the RS485 interface.
