HART ® Input/Output Channels
(3HRT04/3HTSG4)
The 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.
DANGER
Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous area.
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
Insert the 3HRT04 module in any base chassis slot except slot 1 and insert its corresponding
3HTSG4 module below it.
Note: The 3HRT04 module requires a chassis of Revision H or newer.
The 3HRT04/3HTSG4 modules cannot be used in an extension chassis.
You can configure a channel for point-to-point operation in which case it communicates with a
single HART device. Alternatively, you can configure a channel for multi-drop operation in which it
communicates with up to five (5) HART devices in parallel.
