April 2025 HART Input/Output Channels ® (3HRT04/3HTSG4) The DeltaV FB3000 RTU supports a HART (Highway Addressable Remote Transducer) ® module with four (4) channels. This allows the FB3000 to communicate with external HART devices such as transmitters. The 4-Channel HART I/O Module consists of: A logic module (3HRT04) which resides in the upper position of the slot.

Note Whether or not HART devices receive power from an external power supply, you must provide power to the loop terminals (LP+, LP-) of the DeltaV FB3000 power block (3PWBLK). You can configure a channel for point-to-point operation in which case it communicates with a single HART device.
