Compatibility & Replacements
This card module integrates directly into ABB STAL turbine control cabinets and is part of a modular card family that includes related modules such as the 720083 (critical speed card), 720085 (set value control card), and 720091 (frequency output card). When sourcing replacements or upgrades, verify the card slot designation and control signal interfaces within your specific STAL cabinet configuration. Used modules in this family are common in legacy power generation systems; compatibility with newer control platforms should be confirmed with technical documentation.
