9.1 Overview
This section describes how to wire the outputs for QTA DIN AN transmitters. If you don’t know your
transmitter type, see Section 1.6.
It is the user’s responsibility to verify that the specific installation meets the local and national safety
requirements and electrical codes.
9.2 Transmitter Outputs
Table 9-1 describes the outputs and communication protocols available for the QTA DIN rail mount
AN transmitter.
Note: The term “channel” is used to refer to the output terminal pairs.
9.2.1 mA Output Wiring
The following wiring diagrams are examples of proper wiring for the mA output on the QTA DIN rail
mount AN transmitter. The following options are shown:
•
Basic mA output wiring – Figure 9-1
•
HART/analog single-loop wiring – Figure 9-2
•
HART multidrop wiring – Figure 9-3
