■ OPTIONAL SPECIFICATIONS FOR AXFA14 REMOTE CONVERTER “᭛”
Burn Out Down
Lightning Protector
DC Noise Cut
Circuit
A lightning protector is built into the power terminals.
The output level is set to 0 mA during a CPU failure and is set 2.4 mA (-10%) or less during
an alarm. Standard products are delivered with a setting 25 mA during a CPU failure and
21.6 mA (110%) or more during an alarm.
The DC Noise Cut Circuit is built in. Available for 15 mm (0.5 in.) and larger sizes, and for
fluids with the conductivity of 50
µS/cm or higher. Nullifies the empty check and electrode
adhesion diagnostic function.
NAMUR NE43
Compliance
Output signal
limits: 3.8 to
20.5 mA
Failure alarm down-scale: The output level is set to 0 mA during a CPU
failure and is set 2.4 mA (–10%) or less during an alarm.
Failure alarm up-scale. The output level is set to 25 mA during a CPU failure
and is set 21.6 mA (110%) or more during an alarm.
Active Pulse
Output
Waterproof Glands
Active pulses are output in order to drive an external electromagnetic or electronic counter
directly using the converter’s internal power supply. (Nullfies the standard transistor contact
pulse output.)
Output voltage: 24 V DC
±20%
Pulse specifications:
• The drive current of 150 mA or less
• Pulse rate: 0.0001 to 2 pps (pulse/second); Pulse width: 20, 33, 50, or 100 ms
Waterproof glands are attached to the electrical connections. Available only for JIS G1/2
female electric connections.
Plastic Glands
Plastic glands are attached to the electrical connections. Available only for JIS G1/2 female
electric connections.
Stainless Steel
Mounting Bracket
Provided with a JIS SUS304 (AISI 304 SS/EN 1.4301 equivalent) stainless steel mounting
bracket in lieu of the standard carbon steel bracket.
Calibration
Certificate
Level 2: The Declaration and the Calibration Equipment List are issued.
Level 3: The Declaration and the Primary Standard List are issued.
Level 4: The Declaration and the Yokogawa Measuring Instruments Control System are issued.
Epoxy Resin
Coating
Epoxy resin coating which has alkali-resistance instead of standard polyurethane resin
coating. The color is same as standard type.
High Anti-corrosion
Coating
Three-layer coating (polyurethane coating on two-layer epoxy resin coating) in the same
range as that for the standard coating. The color is same as standard type.
Salt/alkali/acid/weather-resistance.
Painting Color
Change
Coated in metallic silver.
Stainless Steel
Tag Plate
Screwed JIS SUS304 (AISI 304 SS/EN 1.4301 equivalent) stainless steel tag plate. Choose
this option when an SS tag plate is required in addition to the standard nameplate with the tag
number inscribed on it.
Dimension (Height
ϫ Width): Appr. 12.5 (4.92) ϫ 40 (15.7) mm (inch)
Waterproof glands with union joints are attached to the electrical connections. Available only
for JIS G1/2 female electric connections.
