Dold relay supplier

Dodd Corporation follows the traditional manufacturing process of the Black Forest region in Germany to produce relay products. It is a family owned enterprise with a history of over 90 years and is currently managed and operated by the third generation successor of the Dodd family. Dodd Corporation has over 400 employees, many of whom are veteran employees who have served the company for more than 20 years. They are familiar with and strictly adhere to the company's quality control standards, which may have deeper significance than simply knowing how. Dodd Corporation has its own machining center, an experienced mold design center, and a modern mold manufacturing factory. Based on these, the company can flexibly design and manufacture according to customer needs, and provide guarantees on delivery time. In addition, Dodd Corporation continuously optimizes electronic and mechanical components to manufacture products with high quality standards.

Dodd relays are mainly classified into production safety relay modules, monitoring relay modules, power relay modules, control relay modules, building automation relay modules, etc.

Our professional security hardware department is one of the research and development divisions for security module products. In the past 15 years, fromearlyThe development of dual hand modules began and later formed a complete product line of security modules. From single function security modules to modular bus based multifunctional security systems, Dodd's security products aim to protect people and machines and provide complete solutions.

Many times, equipment manufacturers, system integrators, or users are not familiar with the relevant safety regulations when designing products, or standard safety products cannot achieve their safety certification, so they cannot follow the corresponding safety regulations well. In order to help customers solve problems, Dodd Corporation customizes special solutions for customers to help them achieve security certification economically and effectively.

The monitoring module is the most important and wide-ranging series of Dodd relay module products. This series is divided into four product branches: insulation monitoring module, leakage monitoring module, measurement relay module, and fault monitoring module. Dodd's monitoring module is used to detect system variables such as voltage, current, power, and insulation impedance, and accurately send signals under strict time constraints, thereby helping people and machinery equipment avoid danger in advance.

In addition, monitoring module products also help reduce downtime of systems or machine equipment, thereby improving production efficiency

Solid state relays/contactors, soft start and motor brake modules are the cornerstone of Dodd's power electronics module product line. These three product groups play an important role in the motor protection control of *. Of course, there are many other applications, especially for solid-state relays, which are widely used in the HVAC and lighting industries.

Dodd is manufacturing PLC products for bus connections, and its industrial protection level even reaches IP67. We also produce various bus input and output modules as expandable peripheral modules for PLCs. Coupling relays are used to connect highly sensitive PLC logic circuits with external operations of machine equipment. Dodd can also flexibly provide customized products with different sizes and contact outputs. Time relays and remote control switches are the cornerstone of Dodd's building automation module products. They belong to the basic equipment of modern building automation system control, mainly used for lighting control. In addition to traditional staircase lighting timer switches and remote control switches, Dodd also has time switches that can set reset and cutoff times, as well as group control andmiddleControl remote switches, etc. This series of products also includes energy-saving switches with remote control and time control functions. In addition, components such as float switches, circuit breakers, and even more advanced hybrid switching relays are also important members of the Dodd building automation product family.

technical advantage

-Forced guided contact technology: Dodd's safety relays use forced guided contact technology to ensure reliable contact operation, prevent contact welding and other faults, and improve safety performance.

-Multiple protection functions: It has overload protection, short circuit protection, undervoltage protection and other functions, which can effectively protect equipment and systems from various electrical faults.

-Intelligent monitoring and diagnosis: Some relay products have intelligent monitoring and diagnostic functions, which can monitor the working status of relays in real time, provide fault alarms and diagnostic information, and facilitate user maintenance and management.

The principle and application details of Dodd DOLD safety relay technology are as follows:

Used in the design of safety circuits that control inputs such as contactors after confirming machine safety.

Main functions of German Dodd DOLD safety relay:

Relays are automatic switching components with isolation functions, widely used in remote control, telemetry

It is one of the most important control components in communication, automatic control, mechatronics, and power electronic equipment.

Relays generally have sensing mechanisms (input parts) that can reflect certain input variables such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc; There is an executing mechanism (output part) that can achieve "on" and "off" control of the controlled circuit; between the input and output parts of the relay, there is an intermediate mechanism (drive part) that couples and isolates the input quantity, processes the function, and drives the output part.

As a control component, in summary, relays have the following functions:

1) Expand control range: For example, when the control signal of a multi contact relay reaches a certain value, multiple circuits can be switched, disconnected, and connected simultaneously according to different forms of contact groups.

2) Amplification: For example, sensitive relays, intermediate relays, etc., can control circuits with high power with a very small control quantity.

3) Integrated signal: For example, when multiple control signals are input into a multi winding relay in a prescribed form, they are compared and integrated to achieve the predetermined control effect.

4) Automatic, remote control, monitoring: For example, relays on automatic devices, together with other electrical appliances, can form program control circuits to achieve automated operation.

German Dodd DOLD safety relay main classification editor:

1. Classify according to the working principle or structural characteristics of relays

1) Electromagnetic relay: utilizing the internal circuit of the input circuit in the electromagnetic iron core

An electrical relay that operates due to the suction force generated between the armature.

2) Solid state relay: refers to a relay in which electronic components perform their functions without mechanical moving parts, and the input and output are isolated.

3) Temperature relay: a relay that operates when the external temperature reaches a given value.

4) Tongue spring relay: using the tongue spring action sealed inside the tube, which has dual effects of electric shock and armature magnetic circuit, to open, close or switch the circuit
