✮  Quick Details

The Emerson 9191-FP is an industrial-grade Power Supply functioning as an advanced 4-segment fieldbus power conditioner module. Engineered to supply clean, isolated DC power across four independent fieldbus segments on a true load-sharing basis, it ensures robust communication network stability. Each module dynamically monitors the health of its connected channels and features an integrated, normally-closed diagnostic alarm relay to instantly flag low-voltage drops or downstream short circuits before they interrupt master DCS communications.

l Output Voltage Per Segment: 28.0 V DC to 32.0 V DC

l Design Output Current (Per Segment): 0 to 250 mA

l Strict Current Limit Threshold: > 320 mA per segment

l Segment Output Alarm Voltage Limit: < 16 V

l Permitted Storage/Transport Temperature: –40 °C to +85 °C

l Relative Humidity Boundaries: < 95% non-condensing relative humidity environment

✮  Product Applications

² Distributed Control System Architecture: Plugs directly into Emerson DeltaV carrier motherboards to power active Foundation Fieldbus H1 segment networks.

² Redundant Power Configurations: Deployed in pairs or groups of three in an N+1 load-sharing setup on carriers to support highly critical, continuous industrial processes.

² Hazardous & Heavy Processing Controls: Utilized across refining, chemical manufacturing, and offshore oil platforms requiring robust galvanic isolation and physical diagnostics to prevent electronic arc faults.
