Benefits
I/O anywhere you need it. DeltaV CHARM I/O
Card (CIOC) provides an unprecedented flexibility in
control system I/O topology. Using standard Ethernet
infrastructure hardware you can add I/O anywhere you
need it. From a local I/O cabinet to remote enclosures
miles away, simply install the hardware and connect it to
the DeltaV control network. Each I/O card can serve I/O
signals to any four controllers in the system with 50 ms
updates for fast, reliable control.
Single channel granularity.
The CHARM I/O
architecture allows each individual channel to be
characterized for the requirements of the field device. Any
instrument signal can be wired to any terminal block. The
channel is then electronically marshalled by installing the
appropriate CHARM and assigning the channel to one of
four controllers. Home run multi-core instrument cables
can be landed in order on a series of CHARM terminal
blocks without concern for signal types.
Reduces installed cost of system.
DeltaV
Electronic Marshalling helps reduce overall system costs
by eliminating internal cabinet cross wiring, reducing
overall footprint, simplifying I/O channel assignments, and
reducing FAT activities. Electronic Marshalling provides
separation between I&E hardware installation schedules
and control strategy development. Wiring can begin
earlier knowing any late changes can be done without
lifting a wire. Separation of the controller and I/O allows
more efficient cabinet designs and accommodates late
scope changes can add I/O anywhere. Adding additional
control capacity does not require re-wiring I/O. Simply
assign the control modules and their I/O signals to the new
controller, without lifting a wire.
Fully redundant communications. The CIOC
architecture is fully redundant. It starts with the two I/O
cards on a carrier. The carrier has redundant
communication modules for primary and secondary
network connections. There are two 24 VDC input power
connections. The carrier connects to the CHARMs
baseplates and provides redundant power and
communication buses to the CHARMs. Everything is
redundant down to the individual channel.
Field mounted capable hardware.
All
components of the CIOC are rated for installation in Class
1/Div 2 or Zone 2 hazardous locations. The extended
operating temperature ranges and G3 environment rating
allows them to be installed in field mounted junction
boxes. This further reduces the footprint required in central
equipment rooms, as well as reduces the overall wiring
infrastructure of traditional multi-core instrumentation
cable.
Plug and Play I/O.
The DeltaV CIOC has been
designed for ease of use, both in physical installation and
its software tools. Components snap together with secure
DIN-rail latches and interlocking carrier connectors.
Attach a series of 96 I/O channels to a DIN-rail in a matter
of minutes. Insert the CHARMs and auto sense the node
to create the I/O definition automatically in your DeltaV
configuration database. CHARMs use a self keying
system to automatically set a channel for a specific
CHARM type. Users cannot mistakenly insert a CHARM
into the wrong terminal block. Assign all, one or any
number of channels to a controller with a simple click or
drag and drop.
CHARM and Terminal Block
Field power is provided through a redundant 24VDC bus
to each CHARM, with up to 100 mA per CHARM. Higher
current Discrete Channels can be powered through
integrated power injection bus local to each CHARM
Baseplate.
