National Instruments SCXI-1120 Analog Input Module

The NI SCXI 1120 (Part Number: 776572-20, 181695G-01) is an ideal affordable solution for the signal conditioning and isolation of several signal types, including: thermocouple, current, volt, millivolt signals, and 4 to 20 mA sources or 0 to 20 mA process-current sources with high common-mode voltages. The SCXI-1120 can also measure strain gauges, RTDs, and thermistors if external excitation is used. This module has eight isolated input channels with 250 Vrms working isolation, along with a few different input ranges. The channels can be separately configured via jumpers. Each of the eight channels additionally has a configurable lowpass filter of 4 Hz or 10 kHz. This Analog Input Module also has a parallel mode operation for high scanning rates. Each of its 8 analog input channels has a gain stage with gains of 1, 2, 5, 10, 20, 50, 100, 200, 250, 500, 1,000, and 2,000; and an output range of ±5 V.

To begin using the NI SCXI-1120, the user needs a computer, a DAQ Device or the SCXI-1200, and either an SCXI-1000, SCXI-1000DC, SCXI-1001, or SCXI-2000 Chassis. The user can also optionally utilize an SCXI terminal block/connector assembly. The SCXI-1120 module has two output modes: parallel-output mode with all eight input channels linked in parallel to eight DAQ device channels or multiplexed-output mode with the eight channels multiplexed into one DAQ device channel. The device is equipped with a 50-pin male ribbon-cable rear connector, and a 32-pin DIN C male front connector (an 18-screw terminal adapter is available). It has an operating temperature of 0 to 50 °C.

For Revision A and B of the SCXI-1120 Analog Input Module, jumper W42 is not utilized. When Revision A and B of the module are cabled to a DAQ device, then the user can only access the MISO line in a single chassis. For Revision C and later of the SCXI-1120, jumpers W42 and W43 can be left in position 1. The device has the dimensions: 1.2 x 6.8 x 8.0 in.

The SCXI-1120 is now regarded as Obsolete and is no longer available from National Instruments, but the Analog Input Module will still be available for purchase and repairs in perpetuity with Apex Waves.
