Dry Contact Closure

Dry contact Closure:

Dry contact may mean any of the following in electronics:

No current: Dry contact can refer to a secondary set of contacts of a relay circuit which does not make or break the primary current being controlled by the relay. Usually some other contacts or devices have the job of starting or stopping the primary current being controlled. For example, a reed relay matrix switch is normally switched with all contacts dry. After the contacts are all connected, a wire spring relay is energized and connects a supervisory scan point, or main switch, through which the primary current being controlled then flows. Dry contacts are primarily employed in 49 volt or less (low voltage) distribution circuits. See also Contactor

No mercury: The wet contact of a Mercury-wetted relay gives certain operational advantages. Dry contacts means a relay that does not use mercury wetted contacts.

Dry joint: A dry contact can be confused with a dry joint, which is a type of poorly soldered joint in which the solder failed to wet the metal. These are liable to fail electrically. The term dry joint is also used less precisely to mean any sort of unsatisfactorily soldered joint.

CanBus is the earliest Bus technology is used in electronic systems, aircraft, tanks and other weapons of communications. Will this technology used in civil car originating in Europe, the bus network is used to the car in the car all kinds of sensor data transfer.

As the CANBUS developing and perfecting, as a kind of advanced technology, high reliability, good function and reasonable cost of remote network communication control mode, the CAN - BUS is no longer limited to automotive electronics field, also is widely applied to various other automation control system. In Europe, the americas, Asia CAN - bus bus technology has been widely applied in the field of engineering machinery, some famous international engineering machinery companies such as CAT, VOLVO, liebherr, widely used in the product CAN - bus bus technology, greatly improve the reliability of the whole machine, CAN be detected and maintainability, and at the same time improve the intelligent level. At home, the CAN - bus bus control system are also beginning to is widely used in auto control system, the construction machinery industry, such as automatic control, intelligent building, electric power systems, security monitoring, etc) are also being gradually popularized.

CANBUS technology application in our country started relatively late, the CIA in 1995 published a full version of CANopen communication protocol, gradually causes some units and the general application of science and technology workers of our country interest. Airlines big at the end of 1996, Beijing university published the CAN BUS principle and application of system design, a book, the application of the CAN BUS enthusiasm was up. Application after that, the CANBUS is like a bamboo shoots is published in the journal of science and technology of all kinds of related, at the same time, these applications like snowball, and so did the colleges and universities and scientific institutes, such as the development of positive enthusiasm and the electronics company of the chip, introduces the application of the CAN BUS technology more widespread inspired CAN - BUS technology research boom. Therefore, be regarded as the most promising fieldbus technology, by industry CAN BUS technology in our country, many in the industry has been widely used, its application level gradually improve. Because the CAN bus technology of good real-time, high reliability, the advantages of the good resistance to electromagnetic interference, make it quickly based on serial data work environment. Application in our country, the CAN - BUS technology is the key in body building monitoring and control system of elevator control system, the robot's distributed control system, ship control system and the medical instrument main monitoring system, testing system, mine monitoring system, and so on many domains, presents a thriving scene.

With China's industrial automation level unceasing enhancement, the CAN - BUS technology will inevitably with the advent of the era of fieldbus, and constantly in our country's economic reforms and the huge demand for open markets and more extensive application.In the fire alarm and other security fields,the control devices cancelled the some RS-485 and RS-232 interfaces and replace them with CAN Bus interfaces due to the high reliability of CAN Bus.In such a high automation world,people are more and more keen on high reliability Bus communications,Can Bus in near future will definitely be the main trend for industrial automation.

AMR and AMI

There’s plenty of room for confusion in today’s marketplace when it comes to defining advanced metering infrastructure (AMI)—the industry has yet to come to consensus on exactly what AMI means. Automated meter reading (AMR), on the other hand, is well defined and well represented.

As the industry leader in advanced metering technology, Itron provides its customers with a clear choice of both AMR and AMI technology. Itron’s AMR offering, ChoiceConnect™, provides proven performance and value along with the flexibility to migrate to more advanced capabilities as business needs change. OpenWay® by Itron is an entirely new generation of metering, communication and control technology designed to support a more expansive set of business and technology requirements for AMI.

To decide which technology is better suited to meet your business needs, it’s important to review the differences between AMR and AMI technology.

What is AMR?

Generally speaking, AMR refers to the ability to collect data from electricity, gas and/or water meters remotely and automatically via different communications networks. AMR is used primarily for monthly customer billing and reduced operational costs. AMR systems typically comprise meters fitted with communication modules, collection systems and supporting software to manage collection of the data. Some fixed network AMR systems, including ChoiceConnect, can also provide interval data collection and outage detection and restoration notification capabilities.

What is AMI?

Most often, AMI refers to systems that are capable of collecting detailed energy usage data frequently. Collection of more timely and granular data enables utilities to support time-based pricing and demand response programs, educate customers on energy consumption and alter usage patterns. AMI data is collected much more frequently, and the type of data collected is much more complex than in a typical AMR system. With AMI systems, this data is key to successful deployment and must be effectively managed.

AMR and AMI in the Marketplace

The business case and technology behind AMR are well-established in the marketplace. The cost savings, efficiency gains, customer service improvements and revenue cycle enhancements provided is the reason why many leading utilities of all types and sizes continue to deploy AMR technology in record numbers—according to the latest industry statistics, traditional AMR technologies still constitute the vast majority of new deployments.

OpenWay by Itron sets a new standard for AMI technology—both in form and function. Fundamentally, AMI represents an infrastructure that utilizes smart meters with advanced two-way communications for collection, querying and meter management. AMI systems empower utility customers to actively and frequently participate in demand response and energy conservation, while supporting movement toward the Smart Grid of the future.

Conclusion

Ultimately, business needs and regulatory conditions drive appropriate technology selection, and AMR technology continues to be a smart choice. Itron’s ERT®-based AMR technology provides the most cost-effective solution for automating collection of meter data for customer billing via drive-by AMR. Yet the system also enables utilities to deploy fixed network collectors over the same population of meters to enable more advanced capabilities such as interval data collection, positive outage and restoration notification. This combination of flexibility, reliability and cost optimization will continue to drive robust AMR system sales well in to the future.

As AMI technology matures, open standards are adopted, costs come down and the business case solidifies, AMI deployments will garner an increased share of the market. But for the foreseeable future, AMR and AMI technology are complementary offerings that will co-exist in the marketplace, with each utility’s unique combination of needs and objectives driving the selection of the most appropriate technology.
