I/O Wiring – Model 2400S Analog Transmitters

3.4.1mA output wiring

The wiring diagrams in this section are examples of proper wiring for the Model 2400S mA output. The following options are shown:

•Internal power:

-Basic mA output wiring – Figure 3-1

-HART/analog single-loop wiring – Figure 3-2

•External power:

-Basic mA output wiring – Figure 3-3

-HART/analog single-loop wiring – Figure 3-4

•HART multidrop wiring, internal or external power – Figure 3-6

Note: If you plan to configure the transmitter to poll an external temperature or pressure device, you must wire the mA output to support HART communications. You may use either HART/analog single-loop wiring or HART multidrop wiring.
