Product Description

The 8I76T400037.00-000 from B&R is a robust and versatile base device specifically designed for the ACOPOSinverter P76 and P74new, making it ideal for modern industrial applications requiring high efficiency and reliability. This unit is engineered to operate with a rated motor power of 0.75 kW, allowing it to handle moderate power loads effectively. The device supports an input voltage range of 3 x 380-500 V, providing flexibility for integration into various electrical systems. To ensure smooth operation and reduce electromagnetic interference, it includes an integrated EMC filter, while the integrated brake chopper enhances braking performance. The max braking torque with brake resistor of 170% of rated motor torque ensures that it delivers exceptional stopping power even under heavy loads, making it suitable for critical applications where precision is paramount.

The 8I76T400037.00-000 also offers significant flexibility in installation, with support for motor cable lengths up to 50 m shielded and 100 m non-shielded, allowing it to adapt to various operational environments. Its input current capability spans from 0 to 20 mA and 4 to 20 mA, paired with a 10-bit resolution and a rapid sampling time of 2 ms, providing accurate and responsive control that is essential for maintaining system performance. The device's input impedance is set at 30 kohm for voltage and 250 ohm for current, which ensures that signals are processed accurately without significant loss or distortion.

Additionally, this unit features a digital outputs nominal voltage of 24 VDC -15%/+20%, and the logic input pulse is capable of handling 20 kbps speeds, which is critical for high-speed data transfer in complex systems. The logic input is short-circuit-proof, with a protection threshold of 50 ohm, offering enhanced safety and longevity under demanding conditions.
