Product Description:
The 8I64T400220.000-1 is an AC inverter manufactured by B&R Automation within the 8I6 ACOPOS Inverters series. Designed for cabinet mounting, this unit receives three-phase mains power and modulates the output frequency to regulate induction motor speed in conveyors, pumps, and other motion tasks common to automated machinery. Through the X2X real-time network, the inverter provides coordinated torque control while maintaining wiring and setup compatibility with other B&R drive components.
The inverter delivers continuous mechanical shaft power of 2.2 kW, making it suitable for small to midsize motors used on secondary packaging lines or indexing tables. The housing stands 184 mm tall, spans 142 mm across the front panel, and extends 158 mm deep, allowing it to fit into compact control enclosures. Its mounting footprint measures 157 mm in height and 126 mm in width. These measurements help preserve the required installation clearances and prevent nearby components from obstructing airflow. Despite its die-cast chassis and internal electromagnetic interference filtering, the device weighs only 2.35 kg, which reduces the load placed on the enclosure during installation. A three-phase input section accepts industrial mains power without requiring external phase conversion.
The control electronics receive power through the X2X backplane at 24 VDC while drawing only 1.6 W, so the module places a minimal load on the system power supply. The digital inputs have a logic input impedance of 12.1 kΩ, which limits source current, and they are refreshed every 4 ms for deterministic command processing. An internal event counter records encoder or sensor pulses at frequencies up to 100 kHz, enabling speed feedback without an external high-speed card. The Do1 safety transistor output has an open-state leakage current of only 3 µA, helping prevent unintended activation of downstream contactors. These response and interface characteristics support operation within synchronized machine networks.
