Available options and ordering information

FP40	Slot A	Slot B
	-XX	-XX	Module code from the table above

Example:

• FP40 with HART module and 6 inputs 4-20mA has a code: FP40-75-11
• FP40 with 6 inputs 4-20mA has code: FP40-11-0

The sign 0 in the above code means that one module is installed in the device (on slot A).
