The Bailey Controls FC120 (often referenced as part of the Bailey Mini-Line series) is a legacy analog/pneumatic process controller. Primarily utilized in older industrial automation and plant process operations, it translates physical process variables (like pressure and flow) into standard pneumatic signals.
- Control Mechanism: Fully pneumatic operation, minimizing electrical spark risks in hazardous or explosive industrial environments.
- Product Line: Belongs to the historic Bailey "Mini-Line" series, sitting alongside sister models like the FC110, FC210, and FC220.
- Signals: Typically operates on standard industrial pneumatic instrument loops (such as 3-15 PSI or 3-27 PSI ranges).
