HC-2/12VDC is a kind of comprehensive remote control device incorporating an encoder and decoder in one package. It can control both AC and DC motors and other electrical appliances, which makes it very suitable for variety of applications. This article will explain its application field and working principle.

Application Field

HC-2/12VDC devices can be used with wide variety of AC and DC motors. It is especially convenient when used with brushless DC motors (BLDC motors) and other appliances operated by electronic control or AC servo motors. Normally, it will be used to control high load switching and provide robotic systems with secondary control functions such as regulation, angle and speed control.

Apart from using it in motor applications, HC-2/12VDC devices can also be employed for controlling other electrical appliances. Some examples include home appliances like lights, heaters, fans, and air conditioners.

Working Principle

HC-2/12VDC device consists of an encoder and decoder. The encoder is used to convert an input signal into a digital signal and transmit it to the decoding unit. The decoding unit then interprets the digital signal and translates it into a physical command. This command is then used to control the current, voltage or frequency of the motor.

The encoding process involves a number of steps such as analog-to-digital conversion, bit manipulation, and ciphering. The analog-to-digital conversion step involves the analog signal being transformed into a digital form. Bit manipulation involves data processing techniques which re-order the data into readable form. The last step, ciphering, involves the encryption of the signal to impair the ability to manipulate the encoded signal.

The decoding process mainly consists of three steps: bit manipulation, deciphering and analog-to-digital conversion. The first step in the process is again bit manipulation to create readable data. The deciphering step then takes the encrypted signal and decrypts it into usable data. Finally, the analog-to-digital conversion step interprets the usable data into a format which the motor can understand.

In conclusion, HC-2/12VDC devices provide an effective means to control both AC and DC motors and other electrical appliances. Its application field is truly versatile while its working process is well studied to ensure reliable transmissions.
