2-WIRE HART
PRetrans 6335
• RTD, TC, Ohm, or mV input
• Extremely high measurement accuracy
®
• HART communication
• Galvanic isolation
• 1- or 2-channel version

Application:

• Linearised temperature measurement with Pt100...Pt1000, Ni100...Ni1000 TC
or sensor.
• Difference or average temperature measurement of 2 resistance or TC sensors.
• Conversion of linear resistance variation to a standard analogue current
signal, for instance from valves or Ohmic level sensors.
• Amplification of a bipolar mV signal to a standard 4...20 mA current signal.
• Connection of up to 15 channels to a digital 2-wire signal with
®
HART communication.

Technical characteristics:

• Within a few seconds the user can program PR6335 to measure temperatures
within all ranges defined by the norms.
• The RTD and resistance inputs have cable compensation for 2-, 3- and 4-wire
connection.
• The 6335 has been designed according to strict safety requirements and is
thus suitable for application in SIL 2 installations.
• A limit can be programmed on the output signal.
• Continuous check of vital stored data for safety reasons.
• Sensor error detection according to the guidelines in NAMUR NE 89.

Mounting / installation:

• Mounted vertically or horizontally on a DIN rail. As the modules can be
mounted without any distance between neighbouring units, up to 84 channels
can be mounted per metre.
• NB: As Ex barrier for 6335D we recommend 5106B.
