SONOFF MINI-ZBD Zigbee Dry Contact Switch Module

• About this product

The SONOFF MINI-ZBD Zigbee Dry Contact switch module is an intelligent module with a potential-free contact, designed to control various devices and automation systems. It communicates using the Zigbee 3.0 protocol and offers NO/NC/COM outputs, allowing for a wide range of applications in home and industrial automation.

• Universal Application of Dry Contact

The SONOFF MINI-ZBD module has a Dry Contact output, which does not supply voltage to the controlled device, but only closes or opens the circuit. This means it can be safely used in many automation installations, regardless of the type of device, and the support for NO and NC contacts allows for operation to be tailored to the system's requirements.

• Stable Zigbee 3.0 Communication

The module communicates using the Zigbee 3.0 protocol, ensuring fast and stable connectivity with low energy consumption. Additionally, it functions as a Zigbee router, extending the network range and improving communication between devices that are far from the hub.

• Advanced Control and Automation

The module allows for remote control, scheduling, and automation scenes in compatible applications. The Detach Relay function allows the physical switch's operation to be separated from the relay's operation, enabling a traditional button to trigger scenes or automations without physically switching the contact.

• Compact Design and Easy Installation

The module has small dimensions of 41 × 43 × 21.5 mm, allowing for installation in junction boxes and limited spaces. The housing is made of durable PC material, ensuring safe and reliable operation in indoor installations.

• Reliability and Durability

The module supports wires with a cross-section of 0.75 to 1.5 mm² and features an impulse resistance of 4 kV, making it suitable for various smart home projects.
