I/O signal connector
Topic LCI-USG-0201, Last Updated 11/08/2024

The I/O signal connector provides a means for the system to communicate with external LC components.

Note: The I/O signal connector was implemented with Alliance iS HPLC system version 1.1. This information applies to systems starting at version 1.1.

The IFM's rear panel includes a removable connector that holds the screw terminals for I/O signals. This connector is keyed so that it can receive a signal cable inserted only one way.
