Product Description:

The 8I76T400400.0P-000 is an ACOPOS inverter manufactured by B & R Automation for the 8I7 series. It converts three-phase line voltage into a controlled output that drives AC motors in automated conveyors, filling stations, and coordinated multi-axis systems that require stable motor control. By combining power conversion, fieldbus connectivity, and braking energy handling in a 60 mm-wide housing, the unit supplies regulated torque and speed while occupying minimal panel space in compact control cabinets.

This inverter can deliver up to 8.6 kVA of apparent power and supports mechanical loads of 4 kW. When connected to a 380 VAC network, the mains current rises to 12.9 A; on 500 VAC systems it drops to 9.9 A, allowing accurate feeder sizing for different plant voltages. The inrush current is limited to 10 A, so upstream protection does not have to accommodate excessive startup surges. Internal losses reach 125 W, which helps determine enclosure ventilation needs. An integrated brake chopper dissipates regenerated energy during fast deceleration, and an integrated EMC filter helps reduce conducted emissions. Six digital inputs accept machine signals, while a single digital output can source 100 mA to actuate relays or indicators for basic control signaling.

The housing measures 325 mm in height, 232 mm in depth, and 60 mm in width, and its IP20 rating limits installation to closed cabinets without direct dust or liquid exposure during normal operation. A short-circuit withstand of 5 kA marks the maximum prospective fault current for the associated circuit breaker. Powerlink communication follows Type 3 guidelines, permitting deterministic real-time exchange with B & R controllers across synchronized automation networks.
