I/O Interface
Section 10A
10A-8
The push-button MTB panel I/O module is included with the push-button
MTB panel. It can also be purchased separately to interface a custom
MTB panel to the control. This module provides 44 inputs and 18 outputs
to the I/O ring.
The push-button MTB panel I/O module is interfaced with the system I/O
ring through fiber optic cables, which are connected to the optical receiver
and transmitter on this module. Refer to Appendix A for additional
information on fiber optic cables and connectors.
Figure 10A.5 shows the external appearance of the push-button MTB panel
I/O module.

Input Interface Ribbon Cable
MTB panel data is sent to the push-button MTB panel I/O module via the
input interface ribbon cable. It is then sent to the control via the fiber optic
I/O ring. Table 10A.D lists the pin assignments for the input interface
ribbon cable for a custom MTB panel. If you are using an Allen-Bradley
MTB panel refer to page 9A-30 for the pinouts of this cable.
