The NI BNC-2095 is a rack-mount signal conditioning adapter designed for National Instruments SCXI modules. It provides 32 BNC connectors for signal input/output paired with a single 96-pin connector for direct SCXI module interface. The unit supports AC/DC coupling with configurable signal referencing through software-controlled switches that manage pull-up and pull-down resistors on a per-channel basis. This enables flexible thermocouple measurement with open circuit detection capability.
Constructed with shielded material and a metal enclosure, the BNC-2095 delivers noise immunity critical for precision measurement environments. Isothermal construction ensures high-accuracy thermocouple readings. The adapter mounts in standard 19-inch racks at 1.7 inches of vertical space.
