IEC PAS 63422:2022 PDF

Overview

IEC PAS 63422:2022 - Zhaga Interface Specification Book 20 including Book 1 defines a standardized, field‑replaceable smart interface between indoor LED luminaires and plug‑in sensing/communication modules. Book 20 specifies the mechanical, electrical and communication interfaces for a LEX (Luminaire Extension) module that connects to the LED driver and control system to provide sensors or network communication. Book 1 provides the common concepts, definitions and general requirements that underlie Zhaga interface specifications and Zhaga‑compliant luminaire components.

Keywords: IEC PAS 63422, Zhaga, Book 20, Book 1, smart interface, indoor luminaires, sensing modules, communication modules, plug‑and‑play.

Key Topics and Requirements

• Interface scope: Defines the smart interface between an indoor luminaire and a LEX‑M (module), enabling sensing or communication functions.
• Mechanical interface: Detailed demarcation models and dimensions for categories (examples in the standard: R44x17, R60x22, C22‑T1, C22‑T2) and the LEX plug/receptacle (LEX‑LP, LEX‑MR).
• Electrical & communication interface: Pin assignments, insulation requirements, contact resistance and support for lighting control protocols (e.g., DALI and DALI bus power).
• Compliance & testing: Test methods and tools (GO‑Gauge, contact making gauges), mechanical and electrical tests for LEX‑M, LEX‑LP, LEX‑MR and luminaires, plus product data set requirements.
• Product data: Annexes describe Product Data Set requirements for LEX‑M and luminaire documentation to support interoperability.
• Plug‑and‑play and performance: Emphasis on safe, replaceable modules and predictable interoperability with luminaire electronics and control systems.

Practical Applications & Who Uses It

• Luminaire manufacturers: Implement Zhaga‑compliant LEX‑LP receptacles and ensure luminaire compatibility with third‑party modules.
• Module makers (sensors/communication): Design LEX‑M modules that mechanically and electrically mate with Zhaga luminaires.
• Lighting system integrators & installers: Deploy field‑replaceable sensing/communication modules for indoor applications (occupancy sensing, daylight harvesting, wireless gateways).
• Specifiers and facility managers: Choose luminaires and modules that meet standardized plug‑and‑play requirements to enable future upgrades and simplify maintenance.

Benefits: faster product integration, interoperability, reduced installation time, and easier field upgrades for smart indoor lighting systems.

Related Standards

• DALI (Digital Addressable Lighting Interface) - referenced for communication and bus power.
• D4i requirements - referenced in luminaire electrical compliance sections.
• IEC family standards - for electrical safety and testing norms.

For architects, product designers and procurement teams focused on smart indoor lighting, IEC PAS 63422 (Zhaga Book 20 + Book 1) is the essential specification for standardized, replaceable sensor and communication modules.
