Responsive Technical Support Contemporary Controls recognizes that Industrial Ethernetis a powerful technology and that understanding how it functions and how it can aid a customer’s application can
be a confusing process. The company continually educates
its market about the workings and benefits of the technology
through seminars, white papers, articles, conferences, websites and through our EXTENSION newsletter articles.
The company provides responsive phone support and technical advice on how best to configure an Industrial
Ethernet application using CTRLink. Vendors of office-grade
equipment seldom answer a call or are unknowledgeable
of the unique requirements of the controls industry. As an example of our commitment to educating the industry,
Contemporary Controls founded the virtual Industrial
Ethernet University (IEU). Extended Product Life Cycle Original Equipment Manufacturers (OEMs) require a stable bill-of-material (BOM) without the additional expense
and effort to requalify a replacement for an obsolete device.
Such is especially true when the OEM equipment has been
qualified for agency approvals and subject to factory surveillance. This can be a challenge when using state-of-
the-art electronic devices, so Contemporary Controls makes
every effort to ensure that its CTRLink line will have an
acceptable product life cycle in support of its OEM customers. But it’s not the case with office-grade equipment
that is frequently changed without notification, making it
difficult to specify and procure the same item even over a
short time span. Regulatory Requirements The industry movement, in embracing Ethernet standards,does not eliminate the requirement to conform to various
agency regulations not required in the office. Seldom does
office-grade Ethernet equipment meet the unique requirements of industrial automation or even building
automation. CTRLink products are designed and tested to thehigherelectromagnetic compatibility (EMC) immunity standards required for
industrial equipment. All the products
are UL 508 Listed as
Industrial control equipment. They are
also C-UL Listed, CSA C22.2 No. 14-M91. Some are listed
under UL 1604, and C-UL C22.2 No. 213-M1987, Non-
Incentive Electrical Equipment for use in Class I, Division 2
Hazardous Location. Still others are UL 864 recognized for
smoke and fire-protective applications. All the products carry
the CE Mark for installation in the European Union. Mounting Why choose CTRLink over office-grade equipment? Control devices are usually mounted onto sub-panels,which are installed into industrial control panels. Devices
are secured by mounting tabs or snapped onto DIN-rails.
CTRLink equipment can be mounted in this fashion resulting
in a nice, clean and rugged installation resistant to vibration.
CTRLink equipment looks like it belongs with its companion
devices. Office-grade equipment is intended for tabletop
installation and seldom has provisions for secure mounting.
Frequently, the units are left unmounted or attached using
Velcro Office-grade Ethernet connectivity equipment also conforms to IEEE 802.3 standards and will successfully communicate with CTRLink. There are several reasons why
CTRLink is superior to office-grade equipment when used inindustrial and commercial applications. >
WhatisCTRLink?
Temperature Office-grade equipment is typically specified over a +5°Cto +40°C temperature range, while industrial controllers
such as
programmable logic controllers (
Plcs) are rated
from 0°C to +60°C. Ethernet equipment should have equal
or better temperature ratings as the equipment to which it
is connected. Many outdoor applications require that the
equipment perform over a wider –40°C to +75°C range.
These two ranges are beyond the capabilities of office-grade
equipment, but they are covered by the CTRLink family without the use of fans (undesirable in industrial applications). CTRLink is a family of Industrial Ethernet products comprised of repeating hubs, switching hubs and media converters used to interconnect modern automation
devices. Contemporary Controls defines Industrial Ethernet
as technology compatible with the Institute of Electrical and
Electronics Engineers (IEEE) 802.3 family of standards, but
designed and packaged for the requirements and rigors of
commercial and industrial applications. Although Ethernet is
now over 30 years old, it has been reinvented several times
to become the local area network of choice for next generation industrial automation,
process control and building automation systems. >
® or
duct tape, or a special shelf is fabricated at additionalcost for their mounting. Office-grade equipment isout of place in an industrial control panel. Power Supply Industrial systems are usually powered from a commonlow-voltage control transformer or low-voltage
Dc power supply. The CTRLink family will operate over a wide range
of AC or DC voltages compliant to the needs of most any
type of control application. The key to this flexibility is a
wide-range DC-to-DC
industrial converter, which can operate during
brownout conditions utilizing a large input
capacitor to ride-out spikes and dropouts that frequently occur with factory
power sources. Additional connections are providedfor redundant power schemes to ensure the greatest
amount of uptime. Office-grade equipment is usually mains-
powered or requires a wall-mounted plug-in transformer
that is inconvenient in a control panel and susceptible to
inadvertent disconnection, compromising the system’s reliability. >
