Read the following before you install the
DX-PCA-Adapter:
- We do not recommend the use of the adapter assembly with the DX-9100 if it was initially installed onto a DIN rail. The adapter requires the use of mounting screws that were used in each corner of the DX base assembly.
- A small number of the early models of the base adapters had a low voltage varistor. Do not use base units with a lot number / date code of 9851 or earlier. This information can be found on a label under the main unit. It may have a prefix of RY1 (and then the four digit date code).
- Installation of the adapter requires the reuse of the DX-9100-8990 base. Be sure that the base unit is in working condition prior to installing the adapter assembly.
- The original
DX-9100-8454 controller had 30 inputs/outputs while the replacement controller has 26 inputs/outputs.
An additional terminal block is provided on the circuit board of the adapter to
accept the following terminations (DI 7, DI 8, AO 13, AO 14). These points are
to be hand-terminated in the field. If these points are required, we recommend
the use of
a PCX module that is capable of controlling the 2 DIs and
2 AOs remaining from the existing configuration. You can connect these points in
a manner that allows the points to be a part of the logic created in the
PCA3613. Note: Depending upon your application, it may be easier to just use the existing wire from the DX base to terminate to the controller. This can be done instead of using the terminal block located under the circuit board. Splicing the wire may be required based on the location of the old to new I/O terminal.
- The adapter is not suitable for use with the DX-9100-8996. This is the base used for door mounting of the controller in the control panel.
- XT/XP modules will need
to be replaced with one or more
PCX modules. Choose the
PCX best suited for your requirements. Note: A PCX module may need to be added in the panel to accommodate all the points needed from the original DX application.
