ABB | Bailey INFI 90 6639890A1

Product Details

• Part Number 1 6639890A1

Product Description

For Bailey Infi 90 system applications, ABB 6639890A1 provides the function of a Standard Relay Panel.

For replacement planning, this component organizes relay-based switching within the control system, allowing lower-level control signals to operate separate circuits while preserving the intended electrical separation. The original wiring and configuration records should guide application.

As part of the Bailey Infi 90 family, this item belongs to an established DCS environment used for modular process control. Application should follow the system drawings and module assignments for the installation. The documented module assignment should remain the basis for selection.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. This is relevant where the installation calls for this specific component class.
