2.5 Wiring

This section describes all wiring requirements and procedures.
CAUTION
All wiring must be done by qualified technicians and must conform to national or local electrical codes.
Do not exceed maximum voltage limits given in Table 1-1.
Which terminals to connect to?
There are 4 main input/output hardware types: Analog Input (AI1 through AI12), Analog Outputs (AO1
through AO4), Discrete Input (DI1 through DI16), and Discrete Outputs (DO1 through DO 24) (your
instrument may have fewer, depending on options ordered). Table 2-3 gives typical applications for each
type. Before wiring your process, you must decide which terminals to connect to your process. The
terminals you connect to correspond with the software in the instrument. For example, the device you
connect to AI1 will be seen by the instrument's software as AI1. If you connect your PV to AI1, then you
must remember that AI1 is your PV; the instrument's software has a labeling feature that lets you identify
each component by a name of your choice.
Your instrument has the terminals shown in either Figure 2-3, Figure 2-4 or Figure 2-5.
Table 2-3 shows typical applications for the various devices that you connect to the terminals.
