I-8K / I-87K I/O Module Selection

Compare I-8K parallel-bus and I-87K serial-bus I/O modules, review module specifications, and check software/platform support.

Selection tip: I-8K modules use a parallel bus for high-speed local PAC I/O. I-87K modules use a serial bus (DCON) and can also be used with supported remote I/O expansion units.
