6. OUTLINE

■ STANDARD SPECIFICATIONS

Refer to IM 01E20F02-01E for FOUNDATION Fieldbus

communication type and IM 01E20F12-01E for

PROFIBUS PA communication type marked with “”

 Converter (Integral flowmeter)

The contents of (*1) and (*2) described in the converter

specifications are follows.

*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 configuration tool

(Such as HTT (handheld terminal) or FieldMate

, etc.)

is necessary to set parameters.

Excitation Method:

• Standard dual frequency excitation:

Size 2.5 to 400 mm (0.1 to 16 in.)

• Enhanced dual frequency excitation:

Size 25 to 200 mm (1.0 to 8.0 in.)

(Optional code HF1 or HF2)

Input Signal (*1) “”:

One Status Input: Dry contact

Load Resistance: 200 Ω or less (ON), 100 kΩ or more

(OFF)

Output Signals “”:

• One Current Output: 4 to 20 mA DC (load resistance:

750Ω maximum, including cable resistance)

• One Pulse Output (*1):

Transistor contact output (open collector)

Contact capacity: 30 V DC (OFF), 200 mA (ON)

Output rate: 0.0001 to 10,000 pps (pulse/second)

• One Alarm Output (*1):

Transistor contact output (open collector)

Contact capacity: 30 V DC (OFF), 200 mA (ON)

• Two Status Outputs (*1):

Transistor contact output (open collector)

Contact capacity: 30 V DC (OFF), 200 mA (ON)

Communication Signals “”:

BRAIN or HART communication signal

(Superimposed on the 4 to 20 mA DC signal)

Distance from Power Line: 15 cm (6 in.) or more

(Parallel wiring should be avoided.)

BRAIN:

Communication Distance:

Up to 1.5 km (0.93 miles), when polyethylene insulated

PVC-sheathed cables (CEV cables) are used.

Communication distance varies depending on the type

of cable and wiring used.

Load Resistance:

250 to 450Ω (including cable resistance)

Load Capacitance: 0.22 µF or less

Load Inductance: 3.3 mH or less

Input Impedance of Communicating Device:

10 kΩ or more (at 2.4 kHz)

HART:

Load Resistance:

250 to 600Ω (including cable resistance)

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 (32132 pixels)

Lightning Protector:

The lightning protector is built into the current output and

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 coating (Munsell 5.6 BG

3.3/2.9 or its equivalent)

Converter Material:

Case and Cover : Aluminum alloy

Mounting/Shapes (Integral Flowmeter):

• Electrical Connection:ANSI 1/2 NPT female

ISO M20 1.5 female

JIS G1/2 (PF1/2) female

• Direction of Electrical Connection: The direction can be

changed even after delivery.

• Terminal Connection: M4 size screw terminal

Grounding:

Grounding resistance 100 Ω or less

When optional code A is selected, grounding resis-

tance 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”.
