✅ Core Specifications (Simplified)

Main Interface: 68-pin female SCSI (for connecting NI DAQ cards, such as E/M/S series, 671x/672x/673x)

Number of BNC Joints: 15 BNC female connectors (50Ω shielded)

AI 0-7: 8 channels (differential / single-ended selectable)

AO 0-1: 2 channels

CTR 0/1: 2 channels of counter

USER 1/2: 2 channels of custom BNC

AI HOLD: 1 channel

Digital / Timing Terminals: 30-pin spring terminal block (P0.0-P0.7, +5V, ground, various timing signals)

Switch below BNC: Each AI channel can be switched to FS (floating ground) / GS (ground reference), suitable for floating or grounded sensors

Shielding: Full metal shielding enclosure, anti-EMI, improving the quality of weak signal measurement

Installation: Desktop flat placement / DIN rail installation (dual-purpose)

Dimensions: 19.05 × 10.48 × 3.51 cm

Temperature: 0 - 70°C (operating)

Driver: NI-DAQmx, compatible with LabVIEW / LabWindows / MAX configuration

?? Usage and Features

In one sentence: Convert 68-pin DAQ card's analog input/output, counter, digital I/O into standard BNC + spring terminals, facilitating direct insertion and removal by oscilloscopes, signal sources, and sensors.

Typical Combinations:

Combined with E series (such as AT-MIO-16E-2 PCI version), M series, S series DAQ

Combined with NI-671x/672x/673x analog output card

Scenarios: Laboratory testing, multi-channel analog signal acquisition on production lines, noise-sensitive low-level measurements (thermocouples, strain gauges, small signal sensors).
