Install the Pro 2 inside the breaker box to remotely switch two independent circuits, such as an outbuilding supply and a garden lighting feed, without running extra control cabling.

Dry Contact Equipment Control

Use the dry contact outputs to interface with existing low-voltage control gear or third-party equipment that needs isolated switching rather than a direct mains relay.

Commercial Two-Phase Automation

Deploy it in a shop or small office to give facilities staff remote and scheduled control over two separate loads, such as signage and ventilation, from one DIN rail device.
