National Instruments ISM-7400

The National Instruments ISM-7400 Integrated Stepper is engineered to optimize the performance and reliability of motorized systems. This versatile stepper motor operates within a supply voltage range of 12 VDC to 48 VDC, making it suitable for a variety of applications. The ISM-7400 features robust protection mechanisms including over-voltage, under-voltage, over-current, and over-temperature safeguards, ensuring the safety and longevity of your system. It is fully compatible with NI 7330, 7340, and 7350 motion controllers, enabling seamless integration.

For optimal thermal management, the ISM-7400 should be mounted on a smooth, flat metal surface to facilitate heat dissipation; the use of an external fan is advisable for applications requiring additional cooling. Secure installation is achieved with four M3 screws, utilizing a mounting hole depth of 4.5 mm. The ISM-7400 is available in three configurations: the standard single-shaft model, the dual-shaft ISM-7400D, and the dual-shaft ISM-7400E, which includes a 1000-line incremental encoder.

To ensure reliable operation, the ISM-7400 features optical isolation and supports logic levels from 5 V to 24 V, accommodating sourcing, sinking, or differential signal configurations for compatibility with various control interfaces. It requires a compatible step signal source, such as a Programmable Logic Controller (PLC) or motion controller, to provide precise control over motor movements. The integrated stepper also incorporates an internal fuse for secure electrical connections to the positive power supply terminal. It offers three essential inputs for control: STEP for controlling rotational movement, DIR for high-speed directional control, and EN for managing motor power.

With dimensions of 1.71 x 2.20 x 2.64 inches and a weight of 14.7 ounces, the ISM-7400 is designed for ease of integration into existing systems. It also comes with a three-year warranty and associated manuals available for download in PDF format.
