HART

Communication Signal:

BRAIN or HART communication signal (superim-

posed on 4 to 20 mA DC signals)

Note: HART is a registered trademark of the HART Com-

munication Foundation.

Conditions of Communication Line:

Supply Voltage: 20.6 to 35 V DC

Load

Resistance:250to600Ω(includingcable

resistance)

Refer to Figure 2.

HART Protocol Revision:

HART protocol revision can be selected from 5 or 7

when ordering. (“-J” only)

The protocol revision can be changed by user con-

guration.

The HART protocol revision at the time of shipment

is shown by the last number at the serial number

column of the name plate.

Indicator (*2):

Full dot-matrix LCD (128 x 64 pixels)

Operational switch: 4 magnet switches (including

push switches)

Lightning Protector:

When optional code A is selected, the lightning pro-

tector is built into the power supply and digital output

terminals.

Protection:

General-purpose Use/TIIS Flameproof type:

IP66/IP67,

NEMAType4X

Explosion proof type except for TIIS:

In the case of explosion proof type except TIIS,

refer to description of “Enclosure” in “HAZARDOUS

AREA CLASSIFICATION”.

Converter Coating:

Case and Cover: Corrosion-resistant coating

Coating Color:

Mint-green paint (Munsell 5.6 BG

3.3/2.9 or its equivalent)

Converter Material:

Case and Cover: Aluminum alloy

Mounting/Shapes:

•

Electrical Connection: ANSI 1/2 NPT female

ISO M20 x 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of100Ωorlessisnecessary.

When the optional code A is selected, grounding

resistance

of10Ωorlessshallberequired.

* This also applies to TIIS explosion proof types.

For an explosion proof type except for TIIS, follow

the domestic electrical requirements in each coun-

try.

Functions

How to Set Parameters (*2):

Both of four push buttons and magnet switches can

be used for setting. The magnet switches can be

used to set parameters without opening the case

cover.

The magnet switches need operational magnets

(optional code BM). These are also available as part

number F9840PA.

Users can choose a language on indicator from Eng-

lish, Japanese, German, French, Italian, and Span-

ish.

Parameterscanalsobesetwiththeconguration

tool (Such as HHT (handheld terminal) or FieldMate,

etc.). The language for the HHT is English only.
