RTI-12307 Overview

You can use the RTI-12307 to connect to any SLSC module supporting fully compatible rear I/O. The two 26-pin MDR connectors provide access to up to 4 banks of signals for DIO, AI, or AO.

Installing the RTI-12307

Figure 1. Installing the RTI-12307 into the SLSC chassis


Caution Do not touch the contacts or remove the I/O boards or cables while the system is energized.

Complete the following steps to install the RTI-12307 in the chassis.

  1. Power off the main DC power source or disconnect it from the chassis before installing any RTIs.
  2. Ensure that the chassis is powered off.
    The POWER LED should be off. If it is not off, do not proceed until it is off.
  3. Loosen the screws of the upper rear panel of the chassis.
  4. Position the RTI-12307 at the desired slot and insert the securing screws, but do not fully tighten them.
  5. Insert an SLSC module into the same slot as its corresponding RTI-12307 while firmly holding the RTI-12307 in place until the RTI-12307 is firmly connected to the module.
  6. Repeat steps 4 and 5 for all required RTIs.
  7. Tighten the screws for all RTI-12307s and the screws of the upper rear panel of the chassis.
    This ensures proper alignment for future connections between modules and RTIs.
  8. Tighten the two module mounting screws on each newly installed module.

Connecting JR1

To connect JR1, complete the following steps.

  1. Prepare a terminal wire for JR1 by stripping insulation and installing a Molex Ultra-Fit™ crimp terminal following the manufacturer's specifications.
  2. Insert a prepared terminal into an appropriate terminal socket of Molex Ultra-Fit™ 8-position receptacle housing.
  3. Repeat steps 1 and 2 for all appropriate terminals.
  4. Insert a receptacle housing into JR1 until the plastic retention latch snaps into place.
    JR1 is keyed to prevent reverse installation of the receptacle housing.
