How to choose the appropriate current relay model?

There are various types of current relays, and different types of current relays have different characteristics and applications. Common current relays include universal current relays, stable current relays, time current relays, voltage current relays, and power current relays. This article will introduce how to choose the appropriate current relay model.

The important criteria for selecting a current relay model include the following:

1. Current load: First, determine the size of the current load that must be controlled to facilitate the selection of a current relay with a suitable rated voltage value.

2. Control voltage: The current relay must select the appropriate rated current value according to the circuit voltage that needs to be controlled.

3. Working environment: The working atmosphere of the current relay should be considered, such as temperature, humidity, vibration, and other factors, and then a suitable current relay should be selected for the environment.

4. Solenoid valve type: according to the load type and control regulations that need to be controlled, select AC relay, DC relay, Solid-state relay and other appropriate solenoid valve types.

5. Solenoid valve function: select the function of the solenoid valve according to the operating regulations, such as single-phase solenoid valve, three-phase solenoid valve, time controller, etc.

In addition, there are the following precautions:

1. Functional requirement

When selecting an electromagnetic valve, consideration should be given to its functional requirements, such as whether it must have seismic immunity, whether it requires high pressure or high temperature capacity, and whether it needs to be connected to high-power loads.

2. Electrical parameters

Electrical parameters include rated current, rated voltage, action time, release time, etc. The electrical parameters of the solenoid valve should be determined based on the actual application field to ensure its normal operation.

3. Size is also a factor that needs to be taken into account when selecting solenoid valves. Due to the different sizes of solenoid valves, it is necessary to choose a suitable solenoid valve based on the on-site installation environment and space regulations.

Generally speaking, the selection of current relay models must fully consider factors such as load, voltage, working environment, solenoid valve type, and function. After reading the above content, you should be very clear about "current relay"
