Product Description:

The 8I64T400075.0X-000 is an inverter module manufactured by B&R Automation for the 8I6 ACOPOS Inverters series. Designed for three-phase mains, the unit converts fixed supply frequency into a variable output that allows precise speed and torque regulation of industrial motors. Integrated STO terminals and local analog and digital I/O let the drive assume both safety and signal-conditioning duties, so it can be mounted close to actuators in automated packaging, material-handling, or process systems.

The drive offers three analog inputs tailored for different sensing tasks. Ai1 presents an input impedance of 30 kΩ, minimizing loading on delicate voltage sources, and it digitizes those signals with a 10-bit converter for basic closed-loop feedback. Ai2 withstands up to ±30 VDC, enabling direct connection to bipolar process transmitters without external scaling. Ai3 is optimized for low-resistance current shunts with an impedance of 250 Ω. Two digital sourcing outputs can deliver up to 100 mA each at a maximum of 30 VDC, providing drive-controlled status lamps or interlocks. A dedicated STO input with 1.5 kΩ impedance accepts safety-rated signals that remove torque within milliseconds, and the P24 auxiliary rail supplies sensors and encoders while limiting output current to protect the internal supply.

The power stage delivers a continuous 0.75 kW to the motor when fed from a three-phase line. Control electronics are supported by a separate feed that can source up to 1.1 A, helping maintain parameter retention and fieldbus communication during mains drops. A form-C relay rated for 5 A resistive load permits isolated fault signaling to higher-level PLCs. Despite these capabilities, the inverter weighs only 1.2 kg and occupies 105 mm in width, 158 mm in depth, and 142 mm in height, or 188 mm when the optional shield plate is fitted. This compact footprint helps maintain shallow enclosures while preserving the spacing needed for EMC compliance.
