Definitions

Warranted Specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical—describes the performance met by a majority of models.
  • Nominal—describes an attribute that is based on design, conformance testing, or supplemental testing.
  • Measured—describes the measured performance of a representative model.

    • Values are Typical unless otherwise noted.

    Conditions

    Specifications are valid under the following conditions unless otherwise noted.

    • All voltages are relative to GND unless otherwise noted.

    RTI-12303 Pinout

    Use the pinout to connect to terminals on the RTI-12303.

    JR1 and XP3

    JR1 is an 8-position Molex Ultra-Fit™ connector. XP3 is an 8-blade Universal Power Module (UPM). XP3 is in the standard position with pinout for fully compatible rear I/O.

    Electrical Characteristics

    Maximum Voltage and Current

    Caution The values in these tables are the maximum rated values for the RTI-12303, however when plugged into an SLSC module, the rated value may be lower. Check the documentation of the SLSC module and use the lower of the rated values.
    Table 10. XP3 and JR1
    Voltage (channel-to-channel, channel-to-ground) +/-60 VDC
    Maximum current rating 8 A
    Current sum of all channels 64 A
    Caution Do not supply hazardous voltages (>30 V RMS/42 Vpk/60 V DC) to the RTI-12303.

    Environmental Guidelines

    Notice Failure to follow the mounting instructions in the product documentation can cause temperature derating.
    Notice This product is intended for use in indoor applications only.
    Notice All cabling should be strain-relieved near input connectors. Take care not to directionally bias cable connectors within input connectors when applying strain relief.
    Notice Cover all empty slots using filler panels.
