Application

• Linearized temperature measurement with Pt100...Pt1000, Ni100...Ni1000, or TC sensor.
• Difference or average temperature measurement of 2 resistance or TC sensors.
• Conversion of linear resistance variation to a standard analog 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 PR6335A 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 6335A has been designed according to strict safety requirements and is thus suitable for application in SIL 2 installations.
• Continuous check of vital stored data for safety reasons.
• Sensor error detection according to the guidelines in NAMUR NE89.

Mounting / installation

• Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without any distance between neighbouring units, up to 84 channels can be mounted per metre.
