Product Details:

NATIONAL INSTRUMENTS CB-68LP is a low-cost unshielded 68-pin screw terminal connector block for NI 68-pin multifunction DAQ hardware. It is equipped with 68 independent screw terminals, matched with vertical 68-pin male SCSI connector for connecting DAQ cables. It comes with metal standoffs, supports desktop placement or fixed installation on custom control panel, and it does not have shielding shell. It is compatible with NI E series, M series, S series and X series 68-pin DAQ boards, including analog input, analog output, digital I/O and counter/timer signals. It is passive wiring accessory without signal conditioning circuit, the maximum voltage rating is 60 VDC, 30 Vrms. This legacy DAQ accessory is end-of-life, available stock are refurbished replacement spares for vintage test and measurement systems.

This terminal block converts compact 68-pin SCSI interface into easy-to-operate screw terminals, convenient for field wiring, signal modification and troubleshooting. It is widely matched with AT-MIO, PCI-MIO, PXI DAQ modules, compatible with LabVIEW, Traditional NI-DAQ and NI-DAQmx driver environments. The screw terminal design provides reliable connection for general analog and digital signals, suitable for sensor signal collection, switch status acquisition and actuator control. It is a cost-effective choice for low-noise non-critical measurement scenarios.

It adopts open PCB structure with metal fixed standoffs, passive design and no external power supply required. One side is vertical 68pin SCSI connector, the other side is arranged with 68 screw terminals. Hot swap operation is not supported; power off the DAQ system before plugging or removing cables. The PCB and terminals meet industrial vibration requirements for bench and panel installation.

It is widely deployed in laboratory measurement stations, production test fixtures, industrial control racks and legacy DAQ systems needing 68pin signal breakout. Typical application scenarios include 68-pin DAQ board wiring conversion, old test bench terminal replacement and vintage measurement platform retrofit. Automation integrators select this NI CB-68LP for its 68 screw terminals,68pin SCSI interface,unshielded low-cost design,panel mount.
