Product Description:
The 8I66T200300.0X-000 inverter is manufactured by B & R Automation within the 8I6 ACOPOS Inverters series. Designed as a drive and I/O module in one, it converts three-phase utility power into modulated motor voltage while collecting local sensor and switch signals. By combining power electronics and control terminals, the unit shortens wiring runs and supports distributed motion architectures common in packaging, assembly, and material-handling systems. It occupies a midrange power class that often feeds servo motors on secondary axes such as feeders, stackers, or small conveyors.
During routine operation, the module delivers a continuous output of 3 kW from a three-phase supply, fitting applications that require moderate mechanical power. Three differential analog inputs capture feedback with 10 bits of resolution, and each channel is updated every 2 ms to maintain a responsive control loop. The isolated input bank contains 6 digital channels that accept signals from proximity sensors, limit contacts, or fault interlocks. Complementary outputs include one 0–10 V analog channel, one transistor switching channel, and two form-C relays, so speed commands and acknowledgment signals can leave the drive without additional interface cards. The aluminum body also houses EMC grounding surfaces that work with cabinet plates to reduce conducted electrical noise.
The cabinet dimensions include a width of 140 mm, a height of 184 mm, and a depth of 158 mm. When additional shielding is required, the optional plate extends the height to 228 mm without changing the rail alignment. The unit weighs 2.2 kg, which reduces the load placed on the cabinet mounting structure and simplifies handling during installation or removal. For field signaling, the programmable switching path can source up to 100 mA at 30 VDC, providing sufficient current for valves, stack-light LEDs, or optically isolated inputs on another controller. The available analog, transistor, and relay outputs allow several external devices to receive commands directly from the inverter.
