Product Description:
B&R Automation supplies the 8I76S200055.0P-000 as part of its 8I7 ACOPOS Inverters series. This compact inverter converts three-phase mains energy into a regulated output for small AC induction or synchronous motors in distributed machine cells. By integrating drive control, safe low-voltage logic, and a fieldbus channel in one housing, it streamlines panel layouts and shortens wiring runs in production lines and material-handling equipment.
The housing carries an IP20 rating, so it is intended for installation in a closed electrical cabinet where ambient dust and moisture are limited. At power-up, the inverter tolerates an inrush of 9.6 A. During steady operation, its nominal output current is 3.7 A, while the mains side draws 5.8 A from a 240 V AC supply. The apparent power processed at full load reaches 1.4 kVA. A dedicated 24 V DC control rail feeds the internal electronics with 1.1 A, and standby losses are capped at 6 W to minimize idle energy use. Control signals enter through six digital and three analog inputs, and two relay outputs provide isolated status feedback. A Type 3 Powerlink interface links the inverter to higher-level PLCs at real-time Ethernet speeds, allowing synchronized axis updates. The transient current capability of 5.6 A for 60 s handles short overloads without tripping.
The power section is rated for a motor shaft load of 0.55 kW, and thermal losses inside the module are limited to 42 W at nominal conditions. Switching devices operate on a carrier frequency of 4 kHz, establishing a compromise between acoustics and dynamic torque control. When a braking resistor is added, its value must not fall below 40 Ω to keep the DC-link voltage within safe limits. Two onboard analog channels can monitor motor temperature or process feedback, while the remaining inputs handle limit switches and support compact single-axis control without auxiliary I/O modules.
