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, touchpoint capacity 5A, 10A, etc., touchpoint forms are diverse.
MY2NJ, MY4NJ series: mostly used in electrical system signal control, such as PLC output, instrument signal control, etc., its touchpoint rated current is 5A, there are 2 groups of normally open/normally closed touchpoints (MY2NJ) and 4 groups of normally open/normally closed touchpoints (MY4NJ) two types.
Precautions for use
Selection and matching: According to the actual control circuit voltage, current, load type and the required number and form of touchpoints and other factors, choose the appropriate model and specification of small intermediate relay to avoid improper selection of relay damage or failure to work properly.
Installation and fixation: When installing, ensure that the relay is firmly installed to avoid loosening or falling off due to vibration, collision, etc., which will affect its normal operation. At the same time, it should be noted that the installation position should be convenient for heat dissipation and maintenance.
Wiring is correct: Strictly follow the pin definition and wiring diagram of the relay to ensure that the wiring of the control terminal and the load terminal is correct to avoid circuit failure or equipment damage due to wiring errors.
