Description:The B&R X20SM1426 is a high-performance stepper motor control module under the X20
system portfolio, engineered for precise 24 VDC stepper motor operation in industrial automation
applications.
The B&R X20SM1426 integrates advanced features such as motor detection, stall protection,
configurable currents, and NetTime synchronization, making the B&R X20SM1426 ideal for tasks
requiring accurate positioning, dynamic motion control, and reliable field device integration.
Below is a structured, visually refined breakdown of the B&R X20SM1426's core specifications,
functional features, and technical details.
The A6370D is widely used in industrial fields that require high-reliability overspeed protection for
critical rotating machinery. The A6370D's typical applications include gas turbines, steam turbines,
compressors, pumps, and power generation equipment. The A6370D is especially suitable for harsh
industrial environments with extreme temperatures (-20 °C to +65 °C) and vibration, providing stable
and reliable protection to minimize equipment downtime and maintenance costs.
