▶FAQ:

Q1. What is a DIN rail relay?
A: A DIN rail relay is an electrical switching device designed for installation on a standard DIN rail inside distribution boards or control panels. It allows connected electrical loads to be switched manually or through an automation system.
Q2. How does a Zigbee relay work?
A: A Zigbee relay receives wireless commands through a Zigbee network to switch connected electrical loads on or off. When integrated with a compatible automation platform, it can also support scheduling, remote control, and automated load management.
Q3. What is the maximum load current of the CB432?
A: The CB432 is available in 32A and 63A versions, allowing system integrators to select the appropriate model for different electrical load requirements.
Q4. Does the CB432 provide energy monitoring?
A: Yes. The CB432 measures instantaneous and accumulated energy consumption of connected electrical loads, combining relay switching and energy monitoring in one DIN rail device.
Q5. Does the CB432 support Zigbee2MQTT?
A: Yes. The CB432 supports Zigbee2MQTT integration for local relay control, energy monitoring, and automation, making it suitable for Home Assistant and custom Zigbee-based systems.
