Product Description:

The 8I64T400037.000-1 is an inverter module from the 8I6 ACOPOS Inverters series manufactured by B&R Automation. Within an automation cell, it functions as a power interface that converts fixed-frequency mains energy into variable-frequency output for motor speed control, allowing coordinated motion or process regulation. The housing has a height of 143 mm, a width of 107 mm, and a depth of 158 mm, which supports cabinet mounting while leaving clearance for airflow. Mounting-hole dimensions of 121.5 mm by 93 mm align with standardized backplate patterns so the unit can be fastened without custom brackets.

The inverter supplies up to 0.37 kW of mechanical output from a three-phase input, a power level suitable for small conveyors, pumps, or positioning axes. Digital control is handled through logic inputs that present a high impedance of 12.1 kΩ, which minimizes loading on PLC output cards. Each input is scanned every 4 ms, so step commands or safety interlocks are detected within a single control cycle. The built-in relay R2 can switch external devices carrying 2 A at 250 VAC, allowing direct actuation of motor contactors or signal lamps. Output DO1 is implemented as a sourcing circuit with only 3 µA of off-state leakage, which helps prevent false triggering of downstream electronics.

Internal fieldbus communication is powered via the X2x interface, which needs only 1.6 W from the backplane and runs from a regulated 24 VDC control supply, isolating signal electronics from the main power section. Despite its cast heat sink and three-leg power stage, the assembly weighs just 1.35 kg, which eases installation on light-duty DIN rails or swing frames. Its compact profile and narrow width permit dense stacking of multiple inverters while keeping access clear around the top-edge terminals. This arrangement also supports orderly routing between the power wiring and the control connections.
