TRICONEX 3481 3401 communication module

Description

The Trident supports a range of modules
for applications with low point counts
and distributed I/O. This section
provides detailed specifications for each
product in the Trident family.
Also included are:
• International approvals (page 23)
• Environmental specifications
(page 24)
• Dimensions and clearances (page 25)
Main Processor Modules
and Baseplates
Every Trident system is controlled by
three Main Processor (MP) Modules
that reside on a single baseplate. Each
MP Module acts as one channel of the
triplicated Trident system. For details,
Communication Module and
Baseplate
The Communication Module (CM) is a
three-to-one interface to the MPs that
enables use of industry-standard
communication protocols. A single
Trident controller can support up to two
CMs on one CM Baseplate with each
CM operating independently. Two CMs
can provide redundant communication
connections or independent communication ports. For details, see page 27.
Analog Input Module
and Baseplates
Each Analog Input (AI) Module has
three isolated channels which independently process analog inputs from field
devices. Each channel transmits the data
to the MP associated with the channel.
The MPs vote the data before passing it
to the application. For details, see
page 32. In addition to the standard AI
baseplate, a HART AI baseplate and a
hazardous location HART AI baseplate
are available.
Analog Input/Digital Input Module
and Baseplates
Each Analog Input/Digital Input (AI/DI)
Module has three isolated channels
which independently process analog and
digital inputs from field devices. Each
channel transmits the data to the MP
associated with the channel. The MPs
vote the data before passing it to the
application. For details, see page 32.
Analog Output Modules
and Baseplates
Each Analog Output (AO) Module has
three isolated channels which independently accept data from the MPs. Voter
circuitry selects a single channel to drive
the output and shunts output from the
other channels. For details, see page 33.
In addition to the standard AO baseplate,
a HART AO baseplate and a hazardous
location HART AO baseplate are available.
Digital Input Module
and Baseplates
Each Digital Input (DI) Module has
three isolated channels which independently process digital input from field
devices. Each channel transmits the data
to the MP associated with the channel.
For details, see page 35.
Digital Output Module
and Baseplates
Each Digital Output (DO) Module has
three isolated channels which independently accept data from the MP associated with each channel. For details, see
