2-Wire HART Transmitter
Key features

1- or 2-channel converter for RTD, TC, Ohm, and bipolar mV signals
2 analogue inputs and 5 device variables with status available
HART protocol revision selectable from HART 5 or HART 7
Hardware assessed for use in SIL applications
Mounting on a DIN rail in Safe Area or Zone 2/22

OVERVIEW

Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100.
HART communication and 4...20 mA analog PV output for individual, difference or average temperature measurement of up to two RTD or TC input sensors.
Conversion of linear resistance to a standard analog current signal, e.g from valves or Ohmic level sensors.
Amplification of bipolar mV signals to standard 4...20 mA current signals.
Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup.

DIN rail mounting with up to 84 channels per meter.
Configuration via standard HART communication interfaces or by PR 5909 Loop Link.

TECHNICAL DETAILS

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.

6337A 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 6337A HART transmitter ensures top measurement performance in harsh EMC environments. Additionally, the 6337A meets NAMUR NE43 and NE89 recommendations.
