The iO1000 provides double the standard notification circuits and significantly higher power (6.0 A vs 3.75 A) compared to the iO64 (Page 6) [1].
It also supports hardware expansion via SDC loop modules and LED display expanders, which are not compatible with the fixed-capacity iO64 (Page 2, 6) [1].
