The National Instruments UMI-7772 (Part Number: 778556-01) is a versatile 2-axis Universal Motion Interface designed specifically for the 73xx series motion controllers from National Instruments. As a compact standalone device, it serves as an essential connectivity accessory, providing dedicated feedback and control connectors that enable independent motion control for each axis. The UMI-7772 features durable D-SUB connectors, ensuring secure and reliable connections to third-party drives. It supports a differential input threshold of ±0.3 V and is fully compatible with limit switches and sensors operating within a 5 V to 30 V range.

Additionally, the UMI-7772 is equipped with global stop inputs that facilitate the simultaneous shutdown of all controlled axes and offers optical isolation on these inputs as well as on inhibit signals, triggers, limits, and digital I/O. This isolation capability minimizes ground loops and mitigates the potential effects of voltage and noise transients, supporting 24 VDC signaling. The interface includes eight digital inputs and eight digital outputs, enhancing its functionality.

For operation, the UMI-7772 can be paired with various drives, including the 3A and 6A AKD analog servo drives, as well as P70530 DC and P70360 AC stepper drives. It is fitted with a 25-pin D-SUB connector and a 68-pin digital I/O connector, allowing for easy integration with appropriate servo or stepper motors. The unit is designed for flexible mounting options, including DIN rail, panel, or rack mount. To operate, a 24 VDC, 10-watt minimum power supply is required, and the unit can be connected to the motion controller using either a 2 m or a 0.5 m SHC68-C68-S cable. A 4-position power terminal block facilitates wiring for 5 to 30 VDC isolated power and 24 VDC power connections. With a weight of 2.5 lbs and dimensions of 10.2 x 5.0 x 0.87 inches, the UMI-7772 is both compact and robust. It comes with a three-year warranty and comprehensive user and maintenance manuals are available for download. For pricing information, please contact a sales representative.
