1. T3H Overview
(2)Expansion interface module
The expansion interface modules for the T3, i.e. IF311, IF351, IF312, IF352 and IF353, are also used with the T3H. When the IF311 or IF312 is used with the T3H, up to three expansion units can be connected, as same as the T3.
On the other hand, the IF321 is a dedicated expansion interface module for the T3H. When the IF321 is used instead of the IF311, up to 6 expansion units can be connected. In the maximum configuration, the T3H can control up to 76 I/O modules.
