Product Description
Overview
The Emerson KJ3007X1-EA1 (12P3275X012) serves as a LocalBus Right Extender for the DeltaV™ M-Series Distributed Control System (DCS). Installed at the rightmost slot of an M-Series carrier, it provides a secure connection for LocalBus expansion cables, ensuring consistent 12.6 VDC logic power and reliable communication across extended I/O segments. This module is essential for scaling DeltaV systems horizontally while maintaining electrical integrity and system reliability.
Key Features
High-Speed Data Continuity
Maintains low-latency communication across multiple carrier assemblies, ensuring seamless integration with controllers and I/O modules on secondary rails.
High-Current Power Support
Delivers up to 8 A at 12.6 VDC to downstream I/O devices, preventing voltage drop across extended LocalBus segments.
Cold-Swap Safety
Not hot-swappable; the system must be powered down before installation or removal to avoid data corruption or electrical hazards.
Secure Mechanical Design
Features a robust locking mechanism to secure the LocalBus expansion cable against vibration, shock, and movement in industrial environments.
Industrial-Grade Environmental Protection
-
Operating temperature: -40°C to +70°C
-
Conformal coating: G3-level protection against moisture, salt, and corrosive gases
-
Shock and vibration rated for harsh environments
-
Fully certified for hazardous locations: Class 1 Div 2, ATEX Zone 2
