ABB AR C093 AE01 HIEE300690R1

The ABB AR C093 AE01 (HIEE300690R0001) is a relay output card designed for ABB’s ACS800 drive systems and legacy DCS platforms. Its core function is to provide isolated relay contact outputs that interface the drive’s internal control logic with external field devices—such as alarm indicators, auxiliary relays, contactors, and interlock circuits—while maintaining galvanic isolation between the low-voltage control electronics and high-potential field wiring.
