FieldPoint Operating Instructions
FP-TB-10
Terminal Base and Dual-Channel
FieldPoint Modules
These operating instructions describe the installation, features, and
characteristics of the FP-TB-10 terminal base and of the various
dual-channel modules that work with it. For details on configuring
and accessing these modules over a network, refer to the user
manual for the particular FieldPoint network module you are using
with the dual-channel system.
Features
The FP-TB-10 and the dual-channel FieldPoint modules have the
following features:
•
High granularity of system design with up to six dual-channel
I/O modules per terminal base
•
Any combination of I/O types in each terminal base
•
Independent isolation of each dual-channel I/O module
FieldPoint dual-channel I/O modules offer maximum flexibility in
configuring I/O systems. You can mount up to six dual-channel
modules in any combination on the FP-TB-10 terminal base. You
can mix dual-channel modules with standard eight- and 16-channel
modules in a single FieldPoint bank. Therefore, you can configure
your FieldPoint system to match your specific I/O needs,
minimizing the size and cost of your distributed I/O system. In
addition, the dual-channel modules provide a flexible solution for
applications requiring channel-to-channel isolation.

  • Page 4 Install the network module first, using two bolts or screws, then install the FP-TB-10 using the right bolt tab. If you use a FieldPoint bus extender cable, the first FP-TB-10 on the new row should use both panel-mount bolt tabs. Installing Dual-Channel I/O Modules You can install up to six dual-channel modules on each FP-TB-10 terminal base.

  • Page 6: Update Rates

    Some dual-channel modules, such as the thermocouple and four-wire RTD modules, provide other means of making field-wiring connections. Update Rates The FP-TB-10 continuously scans through its six dual-channel modules, updating outputs and reading inputs. The scan rate varies depending on the modules in the FP-TB-10. Empty slots and digital modules add 0.2 ms each to the scan time, and analog modules add 1.5 ms each.
