HH52P, HH53P, HH54P, HH62P series: These are some common small intermediate relay models, with AC220V, AC24V, DC12V, DC24V and other rated voltage specifications to choose from, contact capacity 5A, 10A, etc., contact forms are diverse.
MY2NJ, MY4NJ series: mainly used for signal control in electrical instrument system, such as PLC output, instrument signal control, etc., its contact rated current is 5A, there are 2 groups of normally open/normally closed contacts (MY2NJ) and 4 groups of normally open/normally closed contacts (MY4NJ) two types.
Precautions for use
Selection and matching: According to the actual control circuit voltage, current, load type and the number and form of contacts required and other factors, select the appropriate model and specification of small intermediate relays to avoid damage or failure to work properly due to improper selection.
Fixed installation: When installing, ensure that the relay is firmly installed to avoid loosening or falling off the relay due to vibration, collision and other reasons, affecting its normal work. At the same time, it should be noted that the installation position should be convenient for heat dissipation and maintenance.
Correct wiring: Strictly follow the pin definition and wiring diagram of the relay to ensure correct wiring of the control end and the load end to avoid circuit failure or equipment damage due to wiring errors.
