The NI 183904-01 is a 1 meter shielded cable assembly that connects FOUNDATION Fieldbus devices to personal computers via the PCMCIA-FBUS/2 interface. It enables fieldbus device configuration, maintenance, and data logging on desktop, industrial, and notebook PCs. The cable features a DB-9 male D-Sub connector on one end and Combicon-style pluggable screw terminals on the other, with transformer-isolated connection to the fieldbus network. Electromagnetic shielding minimizes interference and ensures compliance with FCC Class A EMC requirements for reliable low-noise signal termination.
