Description

777966-21B NI SCXI-1521B (Part Number: 777966-21B) is a 24-Channel 120 Ohm 1/4-Bridge Strain Input Module from National Instruments, ideal for static and fatigue structural tests with quarter-bridge strain gauges. Featuring fixed-gain amplifiers, Butterworth filters, and programmable excitation, this module can be operated with the SCXI-1317 Terminal Block and various accessories for precise measurements.

777966-21B NI SCXI-1521B (Part Number: 777966-21B) is a 24-Channel 120 Ohm 1/4-Bridge Strain Input Module from National Instruments. This module is ideal for applications requiring a large quantity of channels, such as static and fatigue structural tests with 120 ohm quarter-bridge strain gauges. Each channel features a fixed-gain amplifier and fixed 2-pole Butterworth filter for precise measurements, as well as a 0-5 V programmable excitation source. To operate the SCXI 1521B module, the SCXI-1317 Front-Mounting Terminal Block with screw terminals is necessary. Additionally, accessories such as the SCXI-1310 Connector and Shell Assembly and the TBX-96 DIN-rail Mounted Terminal Block can be used. The front signal connector on the module is a distinct 96-pin DIN C male connector, with specific pins allocated for sensor excitation, quarter-bridge completion resistor, and amplifier terminal connections. Despite being declared as obsolete by National Instruments, the SCXI-1521B module is still available for purchase and repairs through Apex Waves.
