Scaling and the scaling equation

Output Scaling allows translation of engineering unit values used in the control program into electrical signals on the output channel screws.

The module output generates the High signal value when the High engineering value is received from the controller.

It generates the Low signal value when the Low engineering value is received. It generates all other signal values in a linear fashion, depending on the engineering value sent from the controller.

For voltage output types, scaling is defaulted to a 1:1 relationship between the signal values and the engineering units, allowing the module to produce the actual value of the engineering unit sent from the controller.

For current output types, scaling is defaulted to produce a 4 mA to 20 mA output signal for a corresponding 0 to 100% engineering unit value sent from the controller.

This is the scaling equation:
