IEC 62386-332:2017

Overview

IEC 62386-332:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the particular requirements for input devices with feedback functionality within the Digital Addressable Lighting Interface (DALI) system. This standard is part 332 of the IEC 62386 series, which governs digital lighting communications and control systems.

This standard ensures compatibility and interoperability by defining a bus system for controlling electronic lighting components via digital signals, conforming to the requirements of IEC 61347. It specifically addresses control devices that support feedback, enabling communication from input devices back to control systems, enhancing the intelligence and responsiveness of lighting environments.

The publication includes updates from the October 2019 corrigendum, ensuring the most accurate and current protocols for feedback within DALI input devices.
