80190-140-04-R Allen-Bradley Optical Drive Circuit Board

Product Description

Product Overview

The Allen-Bradley 80190-140-04-R is an optical interface circuit board designed for use in Allen-Bradley industrial drive systems, specifically those employing 18-pulse rectifier architectures. This board provides high-integrity optical signal transmission between drive control electronics and power sections, ensuring accurate timing, noise immunity, and reliable operation in high-energy environments.

The 80190-140-04-R is supplied as a field-replaceable PCB assembly and is typically installed within Allen-Bradley medium-voltage or specialty drive platforms where optical isolation is required.

Functional Description

The 80190-140-04-R optical interface board converts electrical control signals into optical signals and vice versa, allowing safe and noise-immune communication across electrically isolated sections of the drive system. This is particularly critical in 18-pulse drive topologies, where precise phase alignment and signal integrity directly impact harmonic mitigation and system stability.

Optical isolation significantly reduces susceptibility to EMI, ground loops, and high-voltage transients common in industrial drive cabinets.
