3.5.1 PI Wiring
Figure 3-9 shows how to wire the pulse input. In the figure, AIDIPI_3 is shown as a dry-
contact pulse input; AIDIPI_4 is shown as an externally sourced pulse input. Pin 5
(ISO_GND) serves as the ground connection for AIDIPI_3 and AIDIPI_4.

Input/Output Channels (3HRT04)
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.
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.
