UR8FH  通用继电器  用于继电器的监测和控制

General Electric Multilin's UR-8FH is a CT/VT module designed to be installed in the general purpose relay family. The relay is equipped with three 1A/5A phase current transformers, 1A/5A ground current transformers and four voltage transformer terminals. Current transformers and voltage transformers are capable of reducing current and voltage to manageable levels, are used for monitoring and control of relays, and are necessary to generate important data for relays.

The UR8FH CT/VT module can use voltage or contact input on channels 1 to 4 or channels 5 to 8. The UR manual provides further information on proper relay connections, pointing out important details such as how channels 1 and 5 are connected to phase A, how channels 2 and 6 are connected to phase B, etc. The manual also provides the user with complete warnings and precautions, for example, how to connect to the relay terminal when the nominal current is 1a or 5a, which must match the secondary rating of the connected ct, lest the user wish to cause damage to the system. In summary, it is important for users to read the general relay manual carefully before starting to connect relays.

UR8FH relay is an electronic component of the control circuit, which controls the circuit on and off by sensing the change of the input current, and is usually used in the automatic control circuit to play the role of automatic regulation, isolation, safety protection and conversion. Relays have many application scenarios, here are some examples:

Automotive: Relays are being used more and more widely in the automotive industry. The more common automotive relays are starting relays for starting motors, honking relays, motor or generator disconnect relays, charging voltage and current regulation relays, transition signal flash relays, light brightness control relays and air conditioning control relays.

Household appliances: In the field of household appliances, relays are widely used in washing machines, microwave ovens, electric heaters and other equipment, used to control the circuit on and off, play a role in protection and control.

Industrial control: In the field of industrial control, relays are widely used in automation equipment, such as mechanical arms on production lines, automated control systems, etc., to achieve automatic control and safety protection of equipment.

Communication equipment: In the field of communication equipment, relays are widely used in switches, routers and other equipment for the transmission and switching of control signals to ensure the stability and reliability of communication.

Smart meters: In the field of smart meters, relays are widely used in smart meters to achieve remote control and automatic meter reading functions.

In general, UR8FH relay is a very important electronic component, widely used in various fields, to achieve circuit protection and control functions.
