NI 4351 devices have a 68-pin shielded latched male connector. ACH± are the 8/16 differential analog input channels. AGND is the analog ground. IEX± are for the current excitation sources (25 μA and 1 mA). DIO are the TTL lines and are referenced to DGND. Software Instrument Driver Use the NI-435x instrument driver to integrate a device into your test software. The instrument driver works with: ◾ NI LabVIEW ◾ NI Measurement Studio ◾ Visual C/C++ ◾ Visual Basic With a computer-based NI 4351 device, you can create distributed measurement systems with ease, taking full advantage of the Web. Recommended Accessories You can choose from several accessories, shown in Table 2, to accurately measure temperature, voltage, or resistance. Measurement Type NI 435x Platforms Accessory Thermocouple only PCI, PXI TC-2190 and SH6868 cable Voltage, resistance, chromatography only PCI, PXI TBX-68 and SH6868 cable Temperature, voltage, resistance, chromatography PCI, PXI TBX-68T and SH6868 cable; CB-68T with CA-1000 and SH6868 cable Table 2.

Use with the SH6868 shielded cable. TC-2190.................................................777510-01 TBX-68T, CB-68T – 68-pin, DIN-rail mountable terminal block with screw terminals for 14 unconditioned temperature, voltage, or resistance signals as well as for excitation. The TBX-68T also has eight digital I/O lines, isothermal design for cold-junction compensation, and autozeroing circuitry on channel 1. The CB-68T is similar to the TBX-68T but is designed to mount inside the CA-1000 custom connectivity enclosure. Both the TBX-68T and CB-68T provide circuitry to increase your sinking and sourcing capabilities to 64 and 15 mA, respectively. They also have two 26-pin connectors to which you can connect digital signal conditioning accessories such as the SSR-8, ER-8, and the SC-206x. TBX-68T.................................................777232-01 CB-68T...................................................777926-01 TBX-68 – General-purpose terminal block to which you can connect up to 16 unconditioned analog signals as well as excitation and digital signals. Use the TBX-68 with the SH6868 shielded cable. TBX-68...................................................777141-01 SH6868 – 68-pin shielded cable terminated with two 68-pin 0.050 series D-type connectors. The cable is used to connect an NI 4351 device to 68-pin accessories such as the TC-2190, TBX-68T, TBX-68, and CB-68T. 1 m ......................................................182419-01 2 m ......................................................182419-02 High-Precision Data Acquisition TC-2190 TBX-68T CB-68T and CA-1000 TBX-68 BUY ONLINE at or CALL 800 813 3693 (U.S.) 4 Specifications » For complete specifications, see the NI 435x User Manual at /manuals.
