Product review

Description

Product Features

Safety control relays are devices that are often used as switches in circuits. According to the type of control voltage required by its coil, it can be divided into AC relay and DC relay. The specifications of the relay are represented by the coil control voltage and contact current. Usually, when the load current is less than 10A, the contact of the relay can be used to connect or disconnect the circuit directly. If the load current is too large, it can be used as an indirect control device.

Electricity in the industrial sector can be controlled by safety relays.

Safety control relays applications need to pay attention to issues

To make good use of safety control relays, the correct selection is very important. First of all, you must have a thorough understanding of the nature, characteristics and use requirements of the controlled object, and careful consideration.

In the same safety control relays, there can be a pair or several pairs of normally open contacts or normally closed contacts (both can also have at the same time), and it can also have a set or array of switching contacts.

Function and application:

In industrial control, the main control functions are completed by general acdc safety relays, which are usually driven by buttons or limit switches. The contacts of safety control relays can control solenoid valves and start larger motors. The voltage is generally 24DVC/220VAC.

The field of digital control has expanded the application of relays. Copy milling and coordinate boring are operated by data programming, and the signals are sent to the machine tool controller, memory unit and other logic elements to control 2 to 5 axes of the coordinate servo motor. With this automatic control method, it is easy to control drilling machines, hexagonal lathes, ordinary lathes and automatic profiling machines.
