Refer to IM 01E20F02-01E for FOUNDATION Fieldbus
communication type and IM 01E20F12-01E for
PROFIBUS PA communication type marked with “”
Converter
*1: Select two points from: one pulse output, one alarm
output, one status input, or two status outputs.
*2: For models without an indicator, the hand-held
terminal is necessary to set parameters.

Note: HART is a registered trademark of the HART
Communication Foundation.
Data Security During Power Failure:
Data (parameters, totalizer value, etc.) storage by
EEPROM. No back-up battery required.
Indicator (*2):
Full dot-matrix LCD (32132 pixels)
Lightning Protector “”:
The lightning protector is built into the excitation current
output, the current output, the signal common, pulse/
alarm/status input and output terminals. When optional
code A is selected, the lightning protector is built into the
power terminals.
Protection:
General-purpose Use/Sanitary Type/TIIS Flameproof
type: IP66, IP67
Explosion proof type except TIIS:
In case of explosion proof type except TIIS, refer to
description of “Enclosure” in “HAZARDOUS AREA
CLASSIFICATION”.
Coating:
Case and Cover: Corrosion-resistant coating
Coating Color; Mint green (Munsell 5.6 BG 3.3/2.9 or its
equivalent)
Converter Material:
Case and Cover: Aluminum alloy
Mounting/Shapes:
• Mounting: 2-inch pipe
• Electrical Connection: ANSI 1/2 NPT female
ISO M20 1.5 female
JIS G1/2 (PF1/2) female
• Terminal Connection: M4 size screw terminal
Grounding:
Grounding resistance 100 Ω or less
When optional code A is selected, grounding resistance
10 Ω or less shall be applied.
* In case of explosion proof type except TIIS, follow the
domestic electrical requirements as regulated in each
country.
* In case of TIIS Flameproof type, refer to description of
“HAZARDOUS AREA CLASSIFICATION”.
Combined Remote Flowtube:
• AXFA14 Converter can be combined with size 2.5 to 400
mm (0.1 to 16 in.) of AXF Remote Flowtube.
• If a combined converter is changed from AXFA14 to
AXFA11 or vice versa, a new meter factor must be
adjusted by flow calibrations.
• In case that size 250 mm (10 in.) or larger is used in low
conductivity or high concentration slurries, please use the
AXFA11 Converter.
