Product Description:

The 8I66S200220.0C-000 is an inverter module produced by B & R Automation within the 8I6 ACOPOS Inverters series. It is a mains-supplied power stage for industrial motors in automated machinery. The unit converts a fixed 240 VAC input to a regulated three-phase output for precision speed and torque control. This arrangement supports motion applications that require stable motor output during changing operating conditions. Because it combines input conversion and motor output control in one module, it suits compact machine sections where panel space is limited.

This drive handles an apparent input power of 4.4 kVA and draws a continuous mains current of 18.5 A at its rated input voltage. During power-up, its inrush current peaks at 19.1 A, so upstream circuit protection must accommodate this transient. An integrated EMC filter limits conducted emissions, while the built-in brake chopper safely redirects regenerative energy to a resistor. Internal losses are limited to 110 W of power dissipation, which simplifies cabinet cooling. The housing has an IP20 protection rating, meaning it is finger-safe but requires installation in an enclosed panel. Communication with higher-level controllers takes place over CANopen, and the short-circuit withstand capability is 1 kA.

On the motor side, the inverter is rated for 2.2 kW of shaft power and supports shielded motor cables up to 10 m in length for installations where the drive cannot be mounted close to the motor. The unit has a mass of 1.6 kg, which keeps the load on DIN-rail supports low. Its width, depth, and height are 105 mm, 158 mm, and 189 mm, which allows high-density mounting next to other ACOPOS units. The compact housing brings power conversion, regenerative braking support, and input filtering into one module, which reduces the need for separate auxiliary components in the panel. Consistent dimensions across the ACOPOS line also help maintain uniform airflow and wire-way spacing inside the control cabinet.
