ATOM HUB SWITCH is a dual-channel programmable power switch designed for ATOM series controllers. It supports independent control of two AC/DC circuits, enabling reliable on/off switching for diverse applications.The module integrates a step-down converter that delivers a stable 5V/1A DC supply to ATOM. Its onboard relay supports up to 250V/10A loads (with 16A surge capacity). For safety, the DC circuit includes overheat and short-circuit protection, automatically cutting off power when abnormal conditions occur.To enhance industrial connectivity, the unit features an SP485EE transceiver, providing an RS485 interface for communication and power input (9–24V). It also includes an HY2.0 expansion port for I2C or GPIO peripherals.With ATOM’s built-in Wi-Fi, the HUB SWITCH enables remote device control. Multiple units can be linked in parallel via RS485, extending system scalability.
