Configurable Features for the Analog Input and Output Modules Chapter 4

The user must do two things to use the output as a current or voltage device:

• Wire for the correct output type (see page

10

)

• Configure accordingly through RSLogix 5000 (see page

35

)

Current Mode

In current mode, the module supports either 0…20 mA or 4…20 mA output
currents independently for each channel, with the latter as default output range.

Voltage Mode

In voltage mode, the module supports ranges of 0…5V, -5…+5V, 0…10V, or -
10…+10V, independently for each channel.

In voltage mode, the outputs are short circuit protected to 20 mA per channel.

High Engineering/Low Engineering

See High Engineering/Low Engineering on page 45.

Fault Mode and Program Mode

The module allows the user to set output states or behavior when in program
mode or fault mode, for each of the four channels. When in program mode the
user can define the following go-to transition behavior for each of the four
channels:

• Hold Last State – instructs the module to maintain last valid state
• Go to Low Clamp – defined in the Limits Configuration tab
• Go to High Clamp – defined in the Limits Configuration tab
• Use Program Value – user defined value in RSLogix 5000

The user can define the following go-to transition behavior for each channel
when the module has a communication fault:

• Hold Last State
• Go to Low Clamp
• Go to High Clamp
• Use Fault Value – user defined fault value

Clamping/Limiting

Clamping limits the output from the analog module to remain within a range
configured by the controller, even when the controller commands an output
