The transmitter (XMTR) may be a HART device, a Bristol 3508
transmitter, or a Bristol 3808 transmitter. HART devices may be multi-
dropped, up to five devices on a channel, allowing up to 40 HART
devices if all eight channels are used. The Bristol transmitters may not
be multi-dropped.
You wire the transmitters differently depending upon whether the
transmitters are multi-dropped, and whether power for the transmitters
is externally or internally sourced.
Internally Sourced Transmitters
Connect the positive terminal of each transmitter to the +24V terminal
(#9 on the board’s terminal block) as shown in Figure 3-33.
Connect the negative terminal of each transmitter to the appropriate
channel terminal on the board’s terminal block. (Also see Table 3-37
and Table 3-38 to identify channel terminals).
