Thank you for looking to Chassis Plans for your I/O requirements.
However, we no longer offer I/O cards as standalone items. Chassis Plans offers multi-vendor system integration of complex rackmount and rugged computer systems. As part of that service, we will accept the responsibility of sourcing and integrating 3rd party I/O cards such as communication and analog/digital cards into these systems to provide complete turn-key solutions.
For your stand alone requirements, we strongly recommend the following two vendors:
