PR electronics 6335D 2-wire HART transmitter. RTD, TC, Ohm, or mV input. HART 5 protocol. Can be installed in Ex zone 0. 1- or 2-channel version. Within a few seconds the user can program PR6335D 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 6335D has been designed according to strict safety requirements and is therefore suitable for application in SIL installations. A limit can be programmed on the output signal. Sensor error detection according to the guidelines in NAMUR NE89.
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.
Mounting / installation
Mounted vertically or horizontally on a DIN rail. Using the 2-channel version up to 84 channels per metre can be mounted.
Configuration via standard HART communication interfaces or by PR 5909 Loop Link.
The 6335D can be mounted in zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I/II/ III, Division 1, Groups A, B, C, D.
