Honeywell 621-9940C is a serial I/O module that gathers data from modules in an IPC 620 serial I/O rack and interfaces the rack with the serial-link architecture.
Honeywell 621-9940C allows individual rack slots to be configured for 0-, 8-, 16- or 32-point I/O density within the total capacity of the installed controller.
DIP-switch banks establish starting address, fault recognition, communication-fault response, test mode and point density for the rack served by Honeywell 621-9940C.
No exact current Honeywell 621-9940C datasheet was located on a Honeywell public URL. Confirm slot position, serial-channel termination, addressing and controller capacity before replacement.
