Product Overview

The BNC‑2110 is a shielded external signal terminal block for NI multifunction DAQ hardware. It converts dense 68‑pin SCSI rear‑connector into convenient front‑panel BNC ports plus spring‑terminal digital‑timing I/O connections, simplifying laboratory and test‑system wiring for analog input, analog output, trigger and counter signals.

Fifteen BNC ports handle analog measurement and waveform‑generation signals; two user‑assignable BNC ports support custom routing for extra timing‑related signals. The 30‑pin spring‑terminal block exposes full digital I/O, PFI, counter‑trigger lines for discrete‑signal wiring. Hardware FS/GS switches under each BNC allow users to configure for floating‑source or ground‑referenced‑source measurements to optimize signal integrity. The metal shielded enclosure reduces EMI interference for low‑level analog signals. It supports both desktop placement and DIN‑rail installation inside instrument cabinetsNI.

Application Notes

• Compatible with NI E‑Series, M‑Series, S‑Series multifunction DAQ boards and NI 671x / 672x / 673x analog‑output DAQ devicesManualsLib.
• FS‑GS configuration must match signal‑source type; improper switch setting will degrade measurement accuracy.
• No built‑in signal conditioning; all gain/filter functions are performed by the connected DAQ hardware.
• Spring terminals accept 28‑16 AWG stranded or solid copper wire; avoid over‑tightening.
• Use shielded BNC coaxial cables for analog signal runs to minimize noise pickup.
• For laboratory and industrial test‑cabinet deployment; not for hazardous‑area field installation.
• Widely used for data‑acquisition test benches, vibration measurement, sensor calibration, automated test‑equipment retrofits.
• Available as new‑old‑stock or refurbished surplus spare part for legacy NI DAQ system maintenance.
