16-channel Zigbee relay module 3.0 for DIN rail Tuya
The 16-channel Zigbee relay module 3.0 is a versatile device designed to control the power supply of peripheral devices such as lighting, roller shutters, projectors, or air conditioning systems. Thanks to full compatibility with the popular Tuya ecosystem and the Home Assistant environment, the controller provides a professional foundation for building an advanced smart home and building automation system.
Key features:
- 16 independent relays equipped with built-in buttons for manual control.
- High circuit load capacity: 4 channels up to 50A and 12 channels up to 16A (voltage and potential-free).
- Full compatibility with the Tuya Smart app and support for advanced scenes and schedules.
- Native integration with the Home Assistant platform (recognized in zigbee2mqtt as ZSVIOT PN16).
- Support for standard, external wall switches (momentary and bistable).
- Standardized and safe mounting in distribution boards on a standard 35mm DIN rail.
Flexible power and load connection options
The device is distinguished by its exceptional versatility in configuration, perfectly adapting to the specifics of complex electrical installations. The module offers different types of outputs for various types of loads.

- N and L: Main module power supply 230V AC.
- 1-4: Voltage relays with a maximum load capacity of up to 50A.
- 5-10: Voltage relays with a maximum load capacity of up to 16A.
- 11-16: Potential-free (Dry Contact) relays with a maximum load capacity of up to 16A.
- RS485: Communication port (reserved, currently not supported).

- RJ45: Ethernet network port (reserved, currently not supported).
- K1-K16: Dedicated inputs allowing the connection of external manual switches that change the state of individual relays.
Hardware requirements and wireless connectivity
For proper operation and full functionality of the controller, a gateway (coordinator) supporting the standard is required Zigbee 3.0 (e.g., compatible with the Tuya system or universal). Communication in this protocol guarantees high stability, low latency, and contributes to strengthening the range thanks to the Mesh function. Support in the zigbee2mqtt system significantly expands the horizons of application, opening the module to fully local automation environments, such as Home Assistant.
