The National Instruments PCI-6023E, with part numbers 777742-01, 185415B-01, and 185415D-01, is a versatile Multifunction I/O device designed for PCI Bus computers. Featuring 16 analog input channels (8 differential) and a maximum sampling rate of 200 kS/s, this device is equipped with two analog output channels and 32 digital I/O lines, all interfaced through a 100-pin connector. The PCI-6023E utilizes a DAQ-STC timing controller, which provides three timing groups dedicated to general-purpose functions, analog input, and analog output counter/timing, boasting seven 24-bit and three 16-bit counters with a maximum timing resolution of up to 50 ns. This controller facilitates functions such as seamless sample rate changes, equivalent time sampling, and buffered pulse generation.

To enhance synchronization of multiple measurement functions, the device is equipped with an RTSI (Real-Time System Integration) bus, allowing integration with up to five data acquisition devices using a ribbon cable. The PCI-6023E operates with the NI-DAQ driver software, ensuring compatibility with various application development environments, including LabVIEW, LabWindows/CVI, Measurement Studio, and VirtualBench, thus streamlining the development process. Additionally, the PCI-6023E can be integrated with an SCXI system for advanced analog signal acquisition from sources such as strain gauges and thermocouples. It supports three input modes: Non-Return-to-Zero (NRSE), Referenced Single-Ended (RSE), and Differential (DIFF), with the flexibility for per-channel configuration. The device dimensions are 6.9 x 4.2 inches, weighing 4.1 ounces. Although the PCI-6023E is designated as end-of-life by National Instruments, it remains available for purchase and repair through Apex Waves.
