Different Parts Related to Wireless Radio Remote Control
Wireless radio remote control systems are widely used in industrial sectors where gigantic machines are used frequently. Controlling these gigantic machines is really very difficult manually. So to avoid accidental incidents as well as to ensure security of the machines, the companies are using industrial remotes. These wireless industrial remotes are widely used in industrial sectors such as bulk transport, industrial petroleum, process controls, and other petro-chemical applications including propane bobtails and refined fuels trucks.
The industrial radio remotes are used generally to ensure interference free control. The modern wireless controllers are included with frequency hopping spread spectrum technology that enables the wireless remotes to shut down the whole system in case of any little signal loss. If any other signal interferes within the range of the remote control system, the frequency hopping system immediately shut down the total machine. This ensures the security of the machines as well as the radio remotes.
The wireless radio remote control systems, whether they are used for petroleum sectors as well as process controls, they mainly consist of two different parts, a powerful transmitter in the handheld wireless controllers and a receiver.
Remote Control Transmitter:
The typical transmitter of the radio remote control has more or less 4 to 6 channels. From them at least four of them are proportional. As a result of this, the controlled surface as well as the devices will always move proportionally to the movements of the control sticks.
The transmitters are generally developed for industrial applications that requires up to 300ft operational range. The transmitters are so powerful that they can catch the tiniest of signals. Depending on the application and the device the transmitters may be different. However, normally, the transmitters can work within a frequency range of 433.92 MHz the transmitters can transmit up to 56 bit DES encryption keys. The whole device is kept under a rugged weatherproof polymer enclosure. Sometimes, the transmitters include an external helical antenna. The antenna has a normal range up to 1000 feet.
The Receiver:
All of the radio remote controllers are combined with a receiver unit. The signal when transmitted by the handheld transmitter is received by the receiver. After that the receiver reads out the signal and works accordingly. The frequency of the receiver is about 2.4GHz DSS or 902-928MHz FHSS. The receiver unit is simply installed by a normal 12/24VDC power supply. The receiver unit is constructed with an IP67 Rated, impact resistant polycarbonate enclosure. The receiver can also be externally mounted if necessary. External antenna is also available. All of the receiver units are pre-wired in order to meet customer requirements. Quick connection fittings are also supplied. These wireless radio remote control receivers are ideal for using up to 8 programmable channels Including LATCHED, MOMENTARY, SAFTY LATCHED, QUERY, ENABLE, and INTERLOCK modes. Sometimes, manufacturers offer to get optional receivers in order to handle higher amperage loads, mix of high side and low side voltage, and dry contact relay outputs.
Apart from that, a wireless remote control system is also included with some other system accessories such as handheld radio joysticks, toggle switches, auxiliary fuse panel, etc.
