Product Details

The ABB 35EK90 GJR5143100R0001, also cataloged as the 35EK90 Bus Coupler Unit, operates as a dedicated hardware component for inter-rack communications and bus interface conversion within ABB Procontic and Procontic T300 platforms. The module manages electrical isolation and data frame conversion between local rack backplane segments and external system buses. Operating within a physical footprint of 20.3 cm x 5.1 cm x 27.9 cm and weighing 0.2 kg, the unit executes high-speed signal routing without introducing processing delay.

Backplane Bus Communication Velocity and Deterministic Networks

When integrated into ABB Procontic rack architectures, the coupler unit preserves high backplane bus communication velocity across expanded controller subracks. Low-latency signal conversion maintains deterministic network timing during cyclic I/O scanning and field bus message transmission. Firmware flash compatibility across connected controller cards ensures synchronized network addressing and system diagnostic execution across expanded bus racks.

Frequently Asked Questions

Q: What precautions are necessary regarding power state when installing or swapping the bus coupler unit?

A: Rack backplane power must be completely turned off prior to inserting or removing the unit. Hot-swapping the coupler can induce voltage transients across backplane contacts and disrupt communication across adjacent I/O racks.

Q: How is shielding managed across the bus coupler physical interface?

A: Interconnecting bus cables must utilize overall foil and braided shielding bonded to the cabinet ground plane to isolate communication lines from high-frequency electromagnetic noise.

Field Installation Guidelines

  • Isolate all rack power sources before aligning and inserting the card into its designated subrack slot.
  • Ensure backplane pin alignment is precise before pushing the module firmly into the chassis bus connector.
  • Secure top and bottom faceplate screws to ensure continuous ground contact between the metal faceplate and the subrack frame.
  • Maintain a minimum clearance of 100 mm above and below the card frame to facilitate natural convective heat dissipation.
