Product Description:

The 8I66T400220.0P-000 is an AC drive produced by B&R Automation within the 8I6 ACOPOS Inverters series. It converts three-phase mains power into regulated motor voltage and current, enabling closed-loop speed and torque control in automated machinery such as conveyors, packaging cells, and material-handling stations. By combining power electronics, field-level I/O, and safety hardware in one housing, the unit simplifies panel construction and supports coordinated motion when connected to higher-level controllers. This arrangement also reduces the need for separate external interface modules in compact control cabinets.

The inverter accepts a three-phase power supply and delivers up to 2.2 kW of mechanical power to the attached motor. Onboard signal processing provides 3 analog inputs for reference values or sensor data, one analog output for process feedback, 6 digital inputs for limit switches, and a single digital output for fault indication. Two form-C relays provide 2 relay outputs with galvanically isolated contact closures that can activate external contactors or alarms. This mix of interfaces supports direct connection to common machine signals without requiring separate I/O hardware for basic control tasks.

The output circuitry can source up to 100 mA per channel at a maximum of 30 VDC, and its refresh period of 2 ms supports real-time capture of transient load events. Safe torque off circuitry presents an impedance of 1.5 kΩ between monitored terminals, allowing standard safety relays to confirm that the power stage is de-energized. The aluminum enclosure measures 140 mm in width, 158 mm in depth, and 184 mm in height, expanding to 228 mm when the supplied shield plate is installed. A mass of 2.1 kg permits mounting directly on DIN rails or inside compact panels without exceeding typical load limits, and the compact housing leaves useful space for cable routing in dense installations.
