Technical Characteristics
Section 2 - Technical Characteristics
• HART® protocol revision can be changed by user configuration to either HART® 5 or HART® 7 protocol.
• The HART® 7 protocol offers:
• Long Tag numbers of up to 32 characters.
- Enhanced Burst Mode and Event notification with time stamping.
- Device variable and status mapping to any dynamic variable PV, SV, TV or QV.
- Process signal trend measurement with logs and summary data.
- Automatic event notification with time stamps.
- Command aggregation for higher communication efficiency.
• TXUN-HT is designed according to strict safety requirements and is therefore suitable for applications in SIL
installations.
• Continuous check of vital stored data.
• Meeting the NAMUR NE21 recommendations, the TXUN-HT HART® transmitter ensures top measurement
performance in harsh EMC environments. Additionally, the TXUN-HT meets NAMUR NE43 and NE89
recommendations.
Mounting / installation / programming
• For DIN form B sensor head or DIN rail mounting.

The outputs of max. 63 transmitters can be connected in parallel for a digital HART 7
communication on 2-wires.
Before it is connected, each transmitter must be configured with a unique number from 1
to 63. If 2 transmitters are configured with the same number, both will be excluded. The
transmitters must be programmed for multidrop mode (with a fixed output signal of 4 mA).
Maximum current in the loop is therefore 252 mA.
The communication is either by means of a HART communicator or a HART modem.
The OMset PC configuration software can configure the individual transmitter for multidrop
mode and provide it with a unique polling address.

For safe installation of TXUN-HT the following must be observed. The module shall only
be installed by qualified personnel who are familiar with the national and international laws,

Em uma atmosfera de gás potencialmente explosiva, o transmissor deve ser montado em um
invólucro a fim de garantir um grau de proteção de no mínimo IP20 de acordo com a ABNT
NBR IEC60529. Se contudo, o ambiente necessitar de um nível de proteção maior, isso deve
ser levado em consideração.
Se o transmissor é instalado em uma atmosfera explosiva exigindo o uso de equipamento de
proteção de nível Ga e se o invólucro é feito de alumínio, ele deve ser instalado de modo que,
mesmo em caso remoto de avaria, fontes de ignição devido ao impacto e fricção, faíscas são
eliminadas.
Se o invólucro é feito de materiais não metálicos, cargas eletroestáticas devem ser evitadas.
Para instalação em atmosfera de poeira potencialmente explosiva, as instruções a seguir são
aplicáveis:
O transmissor deve ser montado em invólucro de metal forma B de acordo com DIN43729 que
está fornecendo um grau de proteção de pelo menos IP6X de acordo com ABNT NBR
IEC60529. O invólucro deve ser adequado para aplicação pretendida e instalado
corretamente.
As entradas dos cabos e os elementos de obturação que podem ser utilizados devem ser
adequados à aplicação pretendida e corretamente instalados.
Para temperatura ambiente >= 60ºC, fios de resistência ao calor devem ser usados com uma
faixa de pelo menos 20K acima da temperatura ambiente.
A temperatura da superfície do invólucro é igual à temperatura ambiente mais 20 K, por uma
camada de pó, com espessura de até 5 mm.

ATENÇÃO - RISCO POTENCIAL DE CARGA ELETROSTÁTICA - VER INSTRUÇÕES
Para a instalação segura do transmissor TXUN-HT em áreas classificadas, deve-se observar o
seguinte:
O módulo necessita ser instalado somente por pessoal qualificado e que tenham familiaridade com
normas internacionais, diretivas e normalização aplicadas à estas áreas.
O ano de fabricação do instrumento pode ser obtido, observando-se os primeiros dois dígitos do seu
número de série.
O circuito do sensor não está com isolação galvânica total em relação ao circuito de entrada. Todavia a
isolação galvânica entre os circuitos é capaz de suportar teste de voltagem de 500 Vac durante 1 minuto.
Appendix
11
O transmissor precisa ser montado em um invólucro com um grau de proteção pelo menos IP-20.
Em atmosferas explosivas compostas por misturas de ar / poeira:
O transmissor somente poderá ser instalado em uma atmosfera potencialmente explosiva composta por
poeira combustível se estiver montado no interior de um invólucro metálico forma B de acordo com a
norma DIN 43729 com um grau de proteção pelo menos IP-6X de acordo com a norma IEC 60529, que
seja adequado para esta aplicação e corretamente instalado.
As entradas dos cabos e outras barreiras a
instaladas.
Onde a temperatura ambiente for ≥60ºC, devem ser utilizados cabos resistentes ao calor que resistam pelo
menos 20K acima da temperatura ambiente.
Se o invólucro onde o transmissor está montado for feito de alumínio e instalado em Zona 0, 1 ou Zona
20,21 ou 22, este não deve conter mais do que 6% do seu peso total de magnésio e titânio.
Acessórios adicionais ao invólucro devem ser projetados e/ou instalados de tal modo que até mesmo
eventos de rara incidência , fontes de ignição causadas por impactos e faíscas por fricção sejam
excluídas.
