Avatto ZWSMMD-4 4 Channel Zigbee RF 433 Dry Contact Relay DC AC 7-32V

Article description:

4 Channel Zigbee & RF Smart Switch

The Avatto ZWSMMD-4-32V allows you to control 4 independent channels simultaneously. This enables up to 4 different devices to be switched on and off separately.

The 4-channel ZigBee switch module with dry contact outputs has been specially designed for the safe control of low-voltage devices up to DC 32V. Each channel supports loads up to 10 A and is ideal for lighting, home automation, gates, control systems and many other applications.

Thanks to the integrated RF module, the channels can also be conveniently controlled using an optional 433 MHz RF remote control.

The relay features dry contact outputs. Regardless of the input voltage, there is no output voltage supplied by the module itself. The input voltage is only used to power the PCB board.

Remote Switching: Conveniently control lights, lamps, PCs and household appliances via Zigbee or RF.

Garage Doors & Gate Control: Ideal for gates, doors and other low-voltage applications.

Motor Control: Suitable for controlling DC and AC motors for forward and reverse operation.

Smart Home Integration: Flexible automation and DIY solution for smart home and professional installations.

Compatibility & Integration (ZigBee / MQTT)

Zigbee2MQTT (MQTT):
Fully supported. All relevant values such as power, current, voltage and energy consumption/generation are reliably transmitted and can be processed directly.

ZHA (Home Assistant / ioBroker):
Generally compatible, however depending on the system environment a custom configuration file (Custom Quirk) may be required. Without adjustment, some values may be limited or displayed incorrectly.

Three working modes

1. Self-locking: Each channel can be switched on and off at the same time. The self -locking mode can be used for many lamps.

2. Locking / interlocking mode: Switch on any channel, the other channels are automatically switched off, and only one channel is switched on at the same time. The locking mode can be used for DC/AC engines.

3. Tip mode / inching mode: Switch on a channel, the channel is automatically closed after 0.5 seconds. The inching mode can be used for RF433 remote control/garage door

The mode can be changed by pressing the mode key.
