Many electronic circuits are designed andare used in low-current circuits. The main task of such circuits is the conversion of input signals, according to the algorithm embedded in them. To separate low-current circuits and higher-voltage circuits, an intermediate relay is used. The scope of their application is quite wide. Due to their small size and reliable operation, such devices are widely used. In addition to galvanic isolation, such relays can perform other functions. They are successfully applied in the schemes of automation, protection and control. An intermediate relay can be found in household electronic devices. They can also be used as auxiliary relays. Samples are successfully used in circuits of both AC and DC.
Many industrial devices operating in thecontrol circuits of technological processes, equipped with intermediate devices, which perform several useful functions. They galvanically unbind the control device from the control circuits and at the same time (using a group of contacts) transmit useful information. Such devices use three types of inputs / outputs: analog, digital and relay. It is not difficult to guess that the relay control signal forms an intermediate relay. It also makes the transition from the electronic circuit to the relay one.
The market of relay devices for todayis quite well developed and represented by various companies that specialize in the production of these products. The intermediate relay "Finder" has good operational characteristics. Italian manufacturers of this type of goods took into account all the features of the use of devices. The relay is manufactured in a protective housing and protected from the majority of possible negative effects during operation. This is moisture, dust, temperature and mechanical damage. The FINDER relay is equipped with a group of contacts, which allow to work simultaneously with a large number of electrical circuits. A standard seat allows the use of conventional connectors when designing. The device can operate in vertical and horizontal positions, which is important when used in industrial installations. The high quality of the materials used in the assembly, and the robotic process line, which excludes the influence of the human factor, complement the overall positive picture.
It should also be noted a large rangevoltage, at which the relay can work. They function well in DC and AC circuits. The nominal voltage of such devices can vary from a few volts to hundreds of them. Samples are perfectly suited for operation in standard electrical networks.
Some types of relay use light andmechanical indication of the triggering, which facilitates troubleshooting the control circuits. In addition, there may be a test button, with which you can actually turn on the relay without power.
