Chapter 5—Input/Output Capabilities

Analog Outputs

 

 

ANALOG OUTPUTS

This section describes the circuit monitor’s analog output capabilities. For

 

technical specifications and instructions on installing the I/O Extender or

 

analog output modules, refer to the instruction bulletin that ships with the I/O

 

(see Table 1–2 on page 3 for a list of these publications).

 

To set up analog outputs, you must first define it from the display. From the

 

main menu, select Setup > I/O. Select the appropriate analog output option.

 

For example, if you are using the IOX0404 option of the I/O Extender, select

 

IOX0404. For detailed instructions, see “Setting Up I/Os” on page 23

 

in Chapter 3—Operation. Then using SMS, you must define the following

 

values for each analog output:

 

Name—A 16-character label used to identify the output. Default names

 

are assigned, but can be customized

 

• Output registerThe circuit monitor register assigned to the analog

 

output.

 

• Lower Limit—The value equivalent to the minimum output current. When

 

the register value is below the lower limit, the circuit monitor outputs the

 

minimum output current.

 

• Upper Limit—The value equivalent to the maximum output current. When

 

the register value is above the upper limit, the circuit monitor outputs the

 

maximum output current.

 

For instructions on setting up an analog output in SMS, see the SMS online

 

help on device set up of the circuit monitor.

CAUTION

HAZARD OF EQUIPMENT DAMAGE

Each analog output represents an individual 2-wire current loop; therefore, use an isolated receiver for each individual analog output on the I/O Extender (IOX).

Failure to observe this instruction can result in equipment damage.
