Honeywell MU-KFTA05 FTA I/O Cable 5M

I/O Redundancy
A one-on-one I/O redundancy option is also available for critical high level analog
inputs, smart transmitter interface connections, analog outputs, digital inputs and digital
outputs. This option offers significantly increased availability of automatic control by
providing continuous operation through failure and replacement of I/O Processors, FTA
cables, backplanes, and AO switching hardware. Up to 40 I/O Processors can be
supported in a redundant or non-redundant PM, APM, or HPM, and the user can
selectively apply redundancy to some or all IOPs, for a maximum of 40 IOP pairs. The
one-on-one design approach offers maximum coverage and fast switchover times.
Integrity of the backup database and of the switching functions is provided through the
extensive diagnostic coverage made possible by the processing capability of the smart
I/O Processors.
