Product Description

Honeywell 621-9928R is a Serial Link Selector for the UCN product family.

For system maintenance, this product is associated with the UCN family and the control system modules category. Configuration and compatibility should be confirmed for the exact system in which it will be used. The plant's maintenance records should support final product selection.
