Is the Telefast ABE-7H16S43 compatible with the BMXDDI3202K and BMXDDI6402K modules?

Published date: 14 October 2019

Issue
In the latest 2019 catalog, it states that the modules are not compatible. The older catalogs stated that it was. Control Expert and the latest Modicon X80 Discrete I/O user manual both state that they are compatible.

Product line
Telefast, Control Expert, Modicon X80

Resolution
It was recently discovered that there’s incompatibility between the X80 DI modules (BMXDDI3202K/6402K) and ABE7H16S43. The leakage current through the red LED (blown fuse indicator) is greater than the threshold current of X80 DI modules and through this path the voltage applied to DI module’s port is greater than the threshold as well.  As of 10/14/2019 the modules are not compatible. 

The following can be used:

Connection bases ->  ABE-7H08R**, ABE-7H08S21, ABE-7H16R**, ABE-7H16S21, ABE-7H16R23

Input adapter connection bases -> ABE-7S16E2** and ABE-7P16F3**
