Network Interface Module Modem Card

The Honeywell 51304511-100 is a NIM (Network Interface Module) Modem card for the Honeywell TDC 3000 distributed control system . It functions as a paddle card within the NIM, providing the physical connections (A and B channels) to the Universal Control Network (UCN) and consolidating the functions of several older legacy components (such as the PNM and PNI I/O) into a single board.
