Zigbee Din Rail Relay Module, 4x16A, 100-230V AC

Smart Zigbee Relay Module Sunricher SR-ZGRM16-DIN4 (4 Channels x 16A, DIN Rail Mounting)

Looking for a powerful, reliable, and versatile solution for smart home or office lighting and electrical device control? The Sunricher SR-ZGRM16-DIN4 is a 4-channel Zigbee controller designed for installation on a standard 35 mm DIN rail in an electrical distribution board. With 4 independent channels, each supporting up to 16A load, this device allows you to easily control even high-power household or industrial equipment.

This Zigbee relay module is designed for seamless integration into universal smart home systems (operating as 4 separate endpoints). Thanks to integrated Zero Crossing technology, relay switching occurs at the optimal moment, significantly reducing inrush current and extending relay service life.

Depending on your requirements, the device can be connected to a Zigbee gateway (Gateway / Hub) or controlled directly using wireless Zigbee remote controls and Zigbee Green Power switches. Its robust design, wide operating voltage range, and 5-year manufacturer warranty ensure long-term and safe operation.

Key Features

• 4 independent channels: Allows separate control of 4 different electrical circuits or devices.
• Powerful 16A switching current: Each channel supports up to 16A load (resistive, inductive, and capacitive loads).
• DIN rail mounting: Designed for convenient and organized installation in an electrical cabinet (standard 35 mm DIN rail).
• Zero Crossing function: Extends relay lifespan and helps prevent contact wear.
• Flexible control: Supports Touchlink direct pairing, Find and Bind mode, and up to 20 Zigbee Green Power switches.
• High reliability: IP20 protection rating, supports OTA firmware updates, and includes a 5-year warranty.

Why Choose This Product?

• Control of high-power devices: Supports up to 3680W (@ 230VAC) per channel. This makes it suitable not only for lighting control but also for heaters, pumps, and other high-power equipment.
• Direct control without a hub (Touchlink): The module can be paired directly with a Zigbee remote control without requiring a central Hub.
• Safer relay switching: Thanks to Zero Crossing Detection technology, relay contacts wear more slowly, allowing the device to last significantly longer, even when switching LED lighting with high inrush current.
• Universal compatibility: Works with most universal Zigbee gateways (Gateway / Hub) available on the market.

Who Is This Product For?

This Zigbee relay module is an ideal choice for a variety of automation applications:

• Smart home automation: Control of lighting zones, blinds, heating, or irrigation systems from the electrical panel.
• Electricians and integrators: Looking for a reliable, DIN rail-mounted 4-channel controller for professional projects.
• Commercial and industrial premises: Management of electrical circuits in offices, warehouses, or workshops, including scheduling and automation.

Practical Applications in Everyday Use

Sunricher SR-ZGRM16-DIN4 application possibilities in an electrical cabinet:

• Lighting zone control: Connect 4 different room or outdoor lighting groups and manage them via an app or automated scenarios.
• Heating device control: Connect electric radiators or underfloor heating manifold actuators.
• Irrigation and pump automation: Set schedules for automatic switching of water pumps or irrigation valves.
• Wireless direct switches: Pair with Zigbee Green Power switches that require no batteries and control the relay from anywhere in the room.

How Does It Solve Complex Control Challenges?

Managing multiple high-power electrical circuits typically requires numerous separate smart relays, which occupy substantial space or are difficult to fit into wall boxes. The Sunricher SR-ZGRM16-DIN4 solves this problem by combining 4 high-power channels into one compact module that mounts neatly on a DIN rail inside an electrical panel. This ensures a clean installation, easy access, and reliable wireless control.

Technical Specifications

Frequently Asked Questions (FAQ)

Is it necessary to use the same phase when wiring this module?
Yes, it is important to note that the power input and all 4 relay inputs must be connected to the same phase; otherwise, the device may be damaged.

Does the device work without a central Zigbee coordinator (Hub)?
Yes, by using Touchlink or Find and Bind modes, you can pair the module directly with remote controls or create a standalone network.

Can DC loads be connected to this module?
Yes, the relay contacts support DC switching up to a maximum of 30VDC.

What happens if the Zigbee connection is lost?
The device retains its functionality and can still be controlled using directly paired Zigbee remote controls or Green Power switches.
