About the Kongsberg 329714

The Kongsberg 329714 is the RAi-16xe, the remote analogue input module of Kongsberg's K-Chief 600 automation system. It reads 16 analogue signals, each selectable as voltage, current or Pt100/Pt1000 resistance with free scaling to engineering units, plus one 5–500 Hz counter input, and supplies excitation power to the sensors. The module checks limits, time-stamps alarms and events and reports to the system over a redundant CANopen field bus. All parameters are held in the module and configured remotely; there are no trimmers or jumpers.

What is the 329714 used for?

The RAi-16xe is mounted close to the sensors it reads, in an engine-room cabinet or directly on the main engine in a suitable enclosure, which keeps sensor cables short. It is the general-purpose analogue input for pressures, levels and temperatures in a K-Chief 600 alarm and monitoring system.

Lifecycle and successor

Before you order

What to photograph or confirm so the right unit is quoted.

Check the part number 329714 and the RAi-16xe marking on the module label, with its revision. The earlier RAi-16 module (8100148) is a different part number from the older DataChief C20 / K-Chief 500 generation. Send a label photo and the vessel name or IMO number.
