Product Details

• Part Number 1 6639890B1

Product Description

ABB 6639890B1 is a Standard Relay Panel for the Bailey Infi 90 product family.

From a maintenance perspective, its function is to provide controlled switching through relay contacts. Coil requirements, contact arrangement, and load limits must match the exact panel or module configuration. Application details remain governed by the exact product revision.

In an Infi 90 installation, modules are assigned distinct control, signal, communication, and support responsibilities. Preserving the exact product identity helps maintain the configuration documented for the affected control node. The installed revision should be confirmed before the product is applied.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. This is relevant where the installation calls for this specific component class.
