6337A 2-Wire HART Transmitter

Brand: PR Electronics

  • 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
  • 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.
