Product Description:

B&R Automation manufactures the 8I74T400055.010-1 in the 8I7 ACOPOS Inverters series. The device is an AC motor inverter that regulates voltage and frequency to match the operating point requested by a PLC or motion controller, enabling closed-loop speed or torque control in production lines, packaging machines, and material-handling cells where repeatable motor response is needed for synchronized movement. It uses Powerlink Type 2 communication for deterministic drive coordination and contains six digital inputs, one digital output, and three analog inputs, so local process signals can be processed without separate I/O modules mounted elsewhere in the control cabinet.

The inverter supplies up to 1.9 kVA of apparent power, indicating the maximum combined real and reactive load it can feed before reaching its thermal limit during continuous service. A nominal output current of 1.9 A corresponds to the continuously available phase current at the configured switching frequency, while the motor terminal can deliver 0.55 kW of mechanical power to the shaft when efficiency factors are considered. During power-up, the line can draw a peak inrush of 10 A, so upstream protective devices must be sized accordingly. Internal losses reach 31 W under rated operation, a figure used to plan cabinet ventilation and avoid excessive enclosure temperature rise.

For protective coordination, the output is rated for a maximum short-circuit current of 5 kA, enabling the selection of circuit breakers with adequate interrupt capacity in fault conditions. The housing measures 45 mm in width, 245 mm in depth, and stands 317 mm tall, so multiple units can be lined up on a DIN rail without exceeding common panel depths or crowding adjacent components. With a mass of 1.715 kg, the module remains easy to handle during installation. Its slim profile leaves room for cooling air channels between neighboring drives, helping the minimum 80 Ω brake resistor dissipate regenerated energy safely during deceleration.
