  • Page 4: Introduction

    Introduction The 3110 and 3120 8-Channel RTD cards can measure temperatures with either eight 3-wire connected resistance temperature detectors or four 4-wire connected resistance temperature detectors (RTD). The analog input card provides isolation between the channels and the RTP system. The RTDs share a common power supply for the precision excitation current sources.

  • Page 5: Specifications

    For long term accuracy, the calibration channels should be monitored to the desired accuracy tolerance. The 3110 cards scans at 1000 samples per second with a -3dB @ 2KHz double pole filter. The 3120 card scans at 43 samples per second with a -6dB @ 9 Hz double pole filter.

  • Page 7: Failure Rates In Accordance To Iec 61508

    Incorrect temperature readings. Failure Rates in Accordance to IEC 61508 The 3110 and 3120 RTD input cards cannot be used for safety-critical functions. The module is non-interfering with other safety-critical modules and therefore can be used for non-safety related functions.

  • Page 8: Cabling

    Cabling Adhere to the specified insulation strip length of 0.26 inches (6.5 mm) when you connect field wiring to the terminal modules; excessive insulation strip lengths causes an electrical hazard. Do not exceed the specified torque when you secure the wires into the terminal module; maximum torque is 2.2 inch-pounds (0.25 N-m).

    4-Wire RTD Selection Jumpers JP200 through JP203 on the card select the RTD wiring type for channels 0 through 7, respectively. The odd numbered channels are not used, therefore only up to four 4-Wire RTD’s can be configured (Channels 0, 2, 4 and 6). Position these jumper plugs on the card as following: Signal 1 Top Channel 0 Sense+...

    When prompted for PASSWORD enter “rtp” (or the correct node password). 6. In RTP NetArrays Select Status for the Node, and observe that the pldprog.pgm file and the CID_0100.PLD (for 3110) or CID_0101.PLD (for 3120) file were received as shown in Status Window 1.
  • Page 15 14. After the PLD update process is complete, all applicable cards in the Node will have their PLDs updated. 15. Turn the power OFF and then back ON at all chassis within the target node. After the power cycle, the 2 files downloaded will automatically be deleted, and the normal node program will be active.

  • Page 17: Netarrays Configuration

    NetArrays Configuration The 3110 RTD card provides eight differential 3-wire or 4-wire resistive temperature device input points. The channel input data can be accessed as either a floating-point engineering units temperature value (Float Variable). Calibration inputs are available for A/D converter testing.

  • Page 18: Redundant Card Id

    Card Properties Redundant Card ID If the inputs of two or three of these cards are connected in a parallel redundant input configuration, a unique Redundant Card ID must be assigned to the cards to identify them as being part of the same parallel redundant group. RTD input cards are considered to be connected in a parallel redundant input configuration if a single RTD is connected to channel 0 of each card, another output device is connected to channel 1 of each card, and so on for every configured channel on the cards.

  • Page 19: Integer Cal Date

    Integer Cal Date This is an encoded date when the card was calibrated in the format YYDDD where YY is the last 2 digits of the year and DDD is the day within the year. Integer Cal Serial Number This is a serial number recorded when the card was calibrated. Integer Error Detection The Error Detection input is an Int Variable that can be used to detect an I/O card failure.

  • Page 20: Integer Channel Error Status

    Bit 2 Cal Low This bit indicates that ground voltages Float Cal Low 00 or Float Cal Low 01 are outside tolerance. Bit 1 Channel Failure This bit indicates that the card has a failure on one or more of its channels. Examine the channel specific error status word to isolate the failed channel(s).

    If the threshold value is exceeded, the filter will reset to the new input value. The units are in mV. Comment Enter up to 255 characters for comments associated with the corresponding tag. The comments are informational only and are not required by any RTP NetSuite application.

  • Page 22: Compliance With Ce Mark

    Compliance with CE Mark This section describes how to install and operate RTP equipment for use in the European Union (EU) to comply with the requirements of the CE Mark and its referenced standards. The procedures in this section apply also to other environments where provisions of the EU’s EMC and Low Voltage Directives are either required or desirable.
  • Page 23 10. The disposal of any electronic products must be in accordance with local regulations (e.g. Directive 2002/96/EC of the European Parliament and of the Council on waste electrical and electronic equipment). Some RTP Corporation products contain materials that may be detrimental to the environment. These materials may include, but are not limited to lead (in solder) and lithium (in batteries).

  • Page 24: Environmental Conditions

    Modules can be ordered with optional HumiSeal© conformal coating. In this case, the modules can be installed in G3 harsh environmental conditions as defined in standard ISA–S71.04–1985. This equipment is intended for use in altitudes up to 2000 meters. Contact RTP regarding use in altitudes higher than 2000 meters.
