Product Description
Overview
The Emerson KJ4001X1-BE1 is a Left-Hand LocalBus expansion module for S-series DeltaV I/O carriers. Designed for system scalability, it enables high-speed communication and power distribution across multiple carrier segments. Installed in the far-left slot of the receiving carrier, it ensures seamless integration with Right-Hand LocalBus ports and expansion cabling. Its rugged design makes it suitable for challenging industrial environments.
Key Features
-
Signal Distribution: Receives LocalBus communication signals and propagates them across the I/O carrier, maintaining timing and signal integrity.
-
Power Handling: Bridges 12.6 VDC LocalBus power and supports bussed field power of 30 VDC at 6.5 A.
-
Environmental Resilience: Operates reliably between -40°C and +70°C, resistant to vibration, shock, and airborne contaminants (ISA-571 Class G3).
-
Enhanced Shielding: Minimizes electromagnetic interference to maintain stable digital communication.
-
Easy Installation: Snap-on design with front-access connector allows rapid deployment or replacement.
