Many electronic circuits are designed and used in low current circuits. The main task of such circuits is the conversion of input signals, according to the algorithm laid down in them. An intermediate relay is used to separate low-voltage circuits and higher voltage circuits. 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 also perform other functions. They are successfully used in automation, protection and control circuits . An intermediate relay can also be found in household electronic devices. They can also be used as auxiliary relays. Samples are successfully used in both AC and DC circuits.
Many industrial devices operating in process control circuits are equipped with intermediate devices that perform several useful functions at once. They galvanically decouple 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 easy to guess that the relay control signal forms an intermediate relay. It carries out the transition from electronic to relay circuitry.
The market of relay devices today is quite well developed and represented by various companies that specialize in the production of these products. The relay "intermediate" possesses good operational characteristics. Italian manufacturers of this type of goods took into account all the features of the use of devices. The relay is made in a protective case and is protected from most of the possible negative impacts during operation. These are moisture, dust, temperature and mechanical damage. FINDER's intermediate relay is equipped with a group of contacts, which allows working simultaneously with a large number of
electrical circuits. A standard footprint makes it possible to use conventional connectors in the design. The device can work in vertical and horizontal positions, which is important when it is used in industrial plants. High quality materials used in the assembly, and a robotic production line that excludes the influence of the human factor, complement the overall positive picture.
It should also be noted a large voltage range at which intermediate relays can operate. They function well in DC and AC circuits.
The rated voltage of such devices can vary from several volts to hundreds of them. Samples are perfectly adapted to work in standard electrical networks.
Some types of relays use light and mechanical indication of operation, which facilitates troubleshooting in control circuits. In addition, there may be a test button with which you can really turn on the relay without power.
