Honeywell 51196094-100 FTA Mounting Channel W/SH Ground Bar

Configured for mechanical cabinet organization and signal shielding execution within distributed control environments, the Honeywell 51196094-100 (51196094-100) FTA Mounting Channel W/SH Ground Bar provides direct physical structural support and low-impedance grounding paths for field termination assemblies.

Hardware Specifications

Honeywell DCS Process Control and Loop Isolation

Installed within control system cabinets supporting Honeywell distributed control architectures, this mounting channel assembly secures Field Termination Assemblies (FTAs) while establishing an equipotential bonding plane for signal cable shields. In process control loops utilizing 4-20 mA HART protocol or FOUNDATION Fieldbus connectivity, maintaining a continuous, low-impedance shield (SH) ground connection is mandatory to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). The integrated shield ground bar prevents common-mode noise coupling, preserving channel-to-channel isolation integrity and protecting sensitive analog conversion circuits from transient voltage spikes.

Frequently Asked Questions

Q: Can the 51196094-100 mounting channel be installed directly onto painted or ungrounded cabinet subpanels?

A: No, mounting channels equipped with integrated ground bars must be bolted directly to bare, unpainted conductive cabinet backplanes to ensure a low-impedance earth ground connection for shield drainage.

Q: How does the integrated shield ground bar interact with field signal cable shielding?

A: Field cable drain wires and overall foil or braid shields are mechanically terminated directly to the ground bar studs or clamps, routing induced noise safely away from the control electronics.

Q: Does this mounting assembly require any internal electrical power connections?

A: No, the 51196094-100 is a passive structural and grounding accessory with zero electrical power consumption.

Field Installation Guidelines

• Mount the channel securely onto bare metal subpanel studs within the control cabinet, ensuring paint or anodization is removed at contact points for proper grounding continuity.
• Terminate individual signal cable shields and drain wires directly to the integrated ground bar to maintain continuous electromagnetic shielding.
• Verify that mounting bolts are torqued tightly to withstand vibration profiles typical of heavy industrial plant environments.
• Ensure adequate physical spacing between high-voltage power raceways and the FTA mounting channel to minimize inductive coupling into signal lines.
