Product Description:

The 8I44S200037.000-1 is a compact inverter from B & R Automation and belongs to the 8I4 ACOPOS Inverters series. It interfaces between the plant supply and a driven motor, generating the variable frequency and voltage needed for closed-loop motion tasks in small material-handling and process modules. By integrating control electronics and power switching in a single module, it simplifies wiring and reduces panel space in distributed automation architectures.

At the input stage, the inverter is rated for an apparent power of 2 kVA, matching branch circuits that feed fractional-horsepower machines. Four differential analog channels are digitized at a 10-bit resolution, enabling proportional speed references without external converters. Discrete control is handled by 4 digital inputs that can gate enable signals or select preset speeds. An integrated EMC filter limits conducted emissions so the unit can share enclosures with sensitive control boards, while the built-in RS485 port running Modbus RTU provides straightforward parameter access. The housing carries IP20 protection and measures 72 mm in width, 121.2 mm in depth, and 130 mm in height, so multiple axes fit on a single DIN rail. A nominal clock frequency of 4 kHz governs the internal PWM, balancing motor acoustics with switching loss.

For the power stage, the drive supplies a nominal output current of 2.4 A to motors up to 0.37 kW. It can tolerate a transient load of 3.6 A for sixty seconds, covering acceleration peaks on conveyors or indexing tables. When running at rated load, its electronics dissipate 27 W, limiting heat rise within a crowded cabinet. The design also withstands a maximum assumed short-circuit current of 1000 A, so standard branch protection devices remain effective.
