Universal multi-line relay is a common control appliance, UR8HH is mainly used to control and protect the normal operation of power systems and equipment. It consists of a group or several groups of contacts, which can be closed or disconnected according to changes in input signals or conditions, thus controlling the on-off state of the circuit.

The UR8HH universal multi-line relay has the following features and functions:

Multi-channel control: The universal multi-line relay can have multiple groups of contacts, and each group of contacts can independently control the on-off of a line or equipment. Therefore, it can control the operation of the circuit in multiple directions.

Automatic control: The universal multi-line relay can receive the input signal and automatically control the closing and breaking of the contact according to the change of the input signal. This makes it suitable for use in automated control systems to achieve automated control logic.

Protection function: universal multi-line relay has overcurrent, overvoltage, undervoltage and other protection functions, which can automatically cut off the circuit or alarm when the circuit is abnormal, and protect the equipment and system from damage.

High reliability: Universal multi-line relays use mechanical contacts or solid state electronic components to achieve circuit on-off control, with high reliability and stability. At the same time, it also has shock-proof, dust-proof and other characteristics, can operate stably in harsh environmental conditions.

Easy maintenance: The structure and principle of the universal multi-line relay are relatively simple, and the installation and maintenance are also convenient. In case of failure, it can be easily replaced or repaired.

In summary, UR8HH universal multi-line relay is a kind of universal control appliance widely used in power system and automatic control system. It has the characteristics of multi-channel control, automatic control, protection function, high reliability and easy maintenance.
