TX801MInput Range Programming Table.

Always set OUTPUT range first, then INPUT range.

DIP switches and trimpots are accessed by removing the small rectangular lid on the top of the TX801M enclosure.

Notes: 1/ Switch status 1 = ON, 0 = OFF, X = DON'T CARE. 2/ All inputs must be of the same signal type.

3/ If using voltage inputs, short unused inputs to 'COM' (terminal 6).

How to Use the Maths Function Formulae.

X, Y, and Z are taken as 0 to 1.0000, representing the full input range.

eg.

4.000mA

=

0.0000

 

8.000mA

=

0.2500

 

12.000mA

=

0.5000

 

16.000mA

=

0.7500

 

20.000mA

=

1.0000

The selected calculation is then performed on the inputs. The output is then SCALED so the resultant range is between 0 and 1.000. (The scaling factor is the factor the largest output must be scaled by to get the result = 1.) This 0 to 1.000 range represents the full output range, as set by the output DIP switches.
