7.3.2 Points of Replacement

The points for replacing the conventional model FP0A21 with the new model FP0RA21 as an
alternative are described below.
 Hardware
• Although the positions of the mode switch and the terminal blocks are slightly different
between the conventional model FP0A21 and the new model FP0RA21, the setting methods
of the switches and the pin layout of the terminal blocks are compatible.
• The mode switch is set in the same way as FP0-A21.
• The connections of the terminal blocks are also the same.
• For the new model FP0RA21, a digital conversion value equivalent to the analog input value
of approx. 2 V is shown for the channels to which no input is connected.
