Siemens 8wd4228-0bb As-interface Adapter Element

Product Description

The SIEMENS 8wd4228-0bb is an AS-Interface adapter element designed for use in industrial signaling and control applications. This adapter provides the mechanical and electrical interface needed to mount and connect AS-Interface signaling elements within a SIRIUS signaling column assembly. The unit measures 52 mm wide by 67 mm high and is constructed from polycarbonate, offering durability and resistance to common industrial environments. Licensed electricians and industrial control technicians are the typical installers. It is suited for facilities requiring structured, bus-based tower light or signaling systems where wiring consolidation and addressable control are priorities.

This adapter element is rated for use with 50 mm diameter AS-Interface signaling elements, supporting up to four elements in a single assembly. It fits into modular SIRIUS signaling column configurations commonly found in manufacturing, automation, and process control environments. The AS-Interface bus architecture allows multiple signaling devices to communicate over a two-wire network, reducing field wiring compared to conventional discrete-wired signal towers. This part is typically installed during panel build or machine assembly phases by qualified industrial electricians or controls integrators.

Key Features

• Polycarbonate construction for durability in industrial environments
• Supports up to four 50 mm diameter AS-Interface signaling elements
• Compact form factor: 52 mm wide by 67 mm high
• Designed for AS-Interface bus-based signaling column systems
• Black housing for standard SIRIUS signaling column aesthetics

Compatibility

Designed for use with 50 mm diameter four AS-Interface signaling elements in SIRIUS signaling column assemblies.

Installation Notes

Installation should be performed by a qualified electrician or controls integrator familiar with AS-Interface bus systems. De-energize the AS-Interface network and any associated control circuits before installing or removing adapter elements. Follow applicable NEC guidelines and the equipment manufacturer documentation for proper assembly sequence and bus addressing. Do not force or overtighten mechanical connections on polycarbonate components, as cracking may result.
