The Allen-Bradley 199-DR1 is a specialized yellow-chromated steel DIN rail designed to provide a high-integrity electrical and mechanical foundation for industrial control components. Within condition monitoring architectures, this specific zinc-plated, yellow-chromate finish is strictly required to establish an optimized, low-impedance grounding path for Bulletin 1440 XM modules via their terminal bases. For longer run applications, the 199-DR4 is available as an extended length variant.
Technical Details
- Part Number: 199-DR1
- Manufacturer: Allen-Bradley
- Type: Yellow-Chromated Steel DIN Rail
- Material: High-tensile steel with zinc plating and a yellow chromate passivated finish
- Profile: Standard 35mm x 7.5mm “Top Hat” geometry
- Primary Function: Mechanical mounting and functional chassis grounding for XM-series terminal bases
- Variant Alternative: 199-DR4 (Identical material and profile in a longer segment length)
Key Features
- Delivers superior surface conductivity over standard clear-zinc or aluminum rails, which is essential for grounding distributed XM monitoring systems and reducing signal noise.
- Features an industrial-grade yellow chromate finish that offers exceptional resistance against oxidation, corrosion, and harsh chemical environments.
- Meets standard 35mm dimension profiles to ensure an exact physical fit and secure snap-on lock with all XM terminal bases (such as 1440-TB-A, 1440-TB-B, and 1440-TB-H).
- Acts as a vital electromagnetic interference (EMI) shield component by providing a direct, low-resistance path to the enclosure’s main ground plane.
Applications
- Mandatory grounding and mounting baseline for Bulletin 1440 XM vibration, speed, temperature, and positioning systems.
- High-noise industrial environments requiring dedicated functional grounding planes for sensitive measurement instrumentation.
- Heavy-duty control cabinet assemblies across manufacturing, petrochemical, and power generation facilities.
