Introduction
The DeltaV™ Media Converters provides an easy way to connect
remote field enclosures with CHARM I/O Cards (CIOC) to the
DeltaV Control Network. Fiber Optic cable can go longer
distances than copper Ethernet cables and these media
converters allow you to extend the DeltaV Control Network
distances up to 15km.
The media converters change the means of communication
from copper to fiber Ethernet and vice versa and facilitates easy
connectivity using both Single-Mode and Multi-Mode Fiber
Optic cable.
There are three different models of DeltaV Media Converters
available with the following port options:
Single-Mode Media Converter with one fiber port and
one copper port
Multi-Mode Media Converter with one fiber port and
one copper port
2-Port SFP Media Converter with one copper port and
2 SFP cages that can be used for copper or fiber SFP modules
(for safe area installation only)
All three DeltaV Media Converters come in a Dual Media
Converter Assembly with a Dual Media Converter Carrier
and two media converters. This facilitates easy deployment
for redundant DeltaV Control Networks.
Benefits
Facilitates deployment of Electronic Marshalling in the field:
DeltaV with Electronic Marshalling can be installed in cabinets
in control rooms but installing it in enclosures in the field will
mean that the I/O is installed closer to the field devices and
thus can reduce the distance between the field devices and
were the wire is terminated to the control system. Many times
fiber optic technology must be deployed in order to connect
CHARM I/O Cards in field enclosures with the controllers
located in the control room building. Emerson has switches
that offer both copper and fiber optic Ethernet, but the DeltaV
Media Converters are specialized devices that will convert from
copper to fiber in order to make it easier to deploy Electronic
Marshalling in the field. Some installations require use of copper
IOPs on the CIOCs to facilitate daisy-chaining of Ethernet
from one CIOC to the next – eliminating the requirement
for switches. The media converters allow longer distances
from the control room to a group of enclosures with CIOCs
daisy-chained in the field.
Supports multiple types of fiber optic: Both Multi-Mode and
Single-Mode fiber types are supported. Multi-Mode can go
distances up to 2km and Single-Mode can go up to maximum
15km distance with proper installation.
Redundant power supply connections: The Dual Media
Converter Carrier includes terminals for redundant 24V DC
Power Supplies and the Media Converter have LED diagnostics
that will indicate any failure in the power supply.
Hazardous area certifications available: The Single-Mode and
Multi-Mode media converters have hazardous area certifications
and can be mounted in Class 1, Div. 2 and Zone 2 hazardous
areas. The 2-Port SFP Media Converter allows various SFP
modules connected to the SFP cages on the media converters
and therefore cannot be certified for hazardous installation.
Includes wire terminals for Easy Installation: Each Dual
Media Converter Carrier includes terminals for redundant power
supplies. These terminals are duplicated to allow daisy-chaining
of the 24VDC power for easy installation. This reduces the need
for a separate terminal block to feed power to additional Media
Converters or CIOCs.
Works with both DeltaV and DeltaV SIS: There are many use
cases for the DeltaV Media Converters covering both DCS and
SIS installations. Although most uses in DCS applications will
be to connect a CIOC to the DeltaV Control Network, it can
also be used to connect Wireless I/O Cards, Ethernet I/O Cards,
DeltaV Controllers, DeltaV Zone 2 Remote I/O etc.
For DeltaV SIS it can be used to connect the SZ Controller
to the DeltaV Control Network, but it can also be used to
connect CSLSs to the SZ Controllers
