Product Description:

The 8I74S200037.010-1 is an AC inverter module manufactured by B&R Automation for the 8I7 ACOPOS Inverters series. It accepts single-phase mains power and produces a controlled three-phase output so that small induction or synchronous motors can be started, stopped, and speed-regulated in automated equipment. Three analog inputs and six digital inputs are provided for reference values and limit switches, while a single digital output reports drive status to the host controller. Typical tasks include conveying, clamping, and auxiliary handling axes that require compact electronics and coordinated motion.

The drive’s motor channel is rated for 0.37 kW of mechanical power. A nominal output current of 3.3 A supports the connected load, and the apparent power drawn from the supply reaches 1.2 kVA; this value is useful when sizing transformers or uninterruptible power supplies. When connected to a 240 V circuit, the inverter draws a steady 5 A, but branch protection must also accommodate the brief inrush current of 9.6 A at power-up. The control electronics are energized by an external 24 VDC feed that requires 1.1 A. The single-phase input simplifies installation in facilities without three-phase auxiliary panels.

Continuous power dissipation is 38 W, and this heat can be removed with normal cabinet airflow. For dynamic braking, the integrated chopper connects to external resistors with a minimum resistance of 40 Ω to limit peak energy. The enclosure has an IP20 rating, so the inverter must be mounted inside a protected panel and does not require special gasketing. The unit measures 45 mm wide, 245 mm deep, and 317 mm high. Its narrow width enables dense installation of multiple inverters on a DIN rail without using excessive horizontal cabinet space.
