Input Mode
The input can be configured so that the incoming
current is scaled across a 4 – 20mA, 0 – 20mA or
linearized across desired points entered in to one of
the two available custom curves.
If 4-20mA is selected and the input current falls
below 4mA, a channel error is generated.
If a curve is chosen and the input falls below the
lowest or highest entered mA input point, a channel
error will be generated.
