For more assistance on configuring the frequency input parameters, see the information provided for 
configuring the frequency output parameters, in Section 8.5.

Note: Be sure to distinguish these discrete input parameters from the discrete input parameters 
described in Section 7.3.5, which are used to assign actions to discrete inputs and discrete events.

These parameters allow you to describe the signal used by the discrete inputs. You can configure each 
discrete input separately. Discrete input options are listed and defined in Table 7-16. See 
Section 7.3.5, Section 11.7, and Chapter 15 for a discussion of the different actions that can be 
triggered by a discrete input.

A Model 3300 controller indicates a flow rate of 5483 grams per 
minute. Calibration of the reference flow element reveals that the actual 
flow rate is 5482 grams per minute.

Use the following formula to calculate the K-factor:

Enter a K-factor of 0.9998.

Active low

Active low

• The input is considered active when the input level is between 0.0 and 0.8 V.
• The input is considered inactive when the input level is between 3.0 and 

30.0 V.

Active high

• The input is considered active when the input level is between 3.0 and 

30.0 V.

• The input is considered inactive when the input level is between 0.0 and 

0.8 V.
