External Fusing Modify for 24vdc Momentum I/O Modules

Issue
The purpose of this Resolution is to inform users of 24vdc Momentum I/O Bases that the fusing requirement has changed.

Using a 315ma fast blow fuse on a redesigned 24vdc Momentum base may cause the fuse to blow when powered upward. Since the 24vdc Momentum I/O bases have been redesigned to encounter the new EMC and power hold-upwardly requirements, it was necessary to increase the size of the external fusing.

The external fusing is indicated in the User Manuals as follows. It does non bear upon the recommended fusing for the I/O power.

Environment

Resolution
The recommended size of the external fuse for all Momentum I/O modules that are powered by 24 VDC, has changed from a 315ma Fast Blow fuse to a 1Amp Tedious Blow fuse (Bussmann GDC-1A or equivalent).

The 1A Dull Blow fuse can be used on both new and onetime versions of 24vdc powered Momentum I/O bases listed below.
