Operation of a radio remote control

A radio remote control always consists of a handheld remote (transmitter TX) and a receiver (transceiver RTX). A wireless radio remote control is also often referred to as a Wireless Remote Control (RC) or Remote Transceiver (RTX). When a button on the handheld remote is pressed, it sends a coded radio signal to the remote transceiver using the frequency 868 Mhz. The transceiver then switches current to the desired function by means of an electrical relay (e.g. open gate or pull in winch rope). The coding for the radio signal is unique to each radio remote control. This means that a radio remote control can never trigger an action on a different receiver.

Our handheld remote controls have a range of approx. 50-100 m, which enables the user to move around the site as required. The range may be less if the receiver is installed in an area where radio signals are impaired, i.e. inside a vehicle. An external antenna can be used to improve the signal. For safety reasons, the handheld remote control does not allow two switching commands to be sent simultaneously. The robust, laterally non-slip housing of the handheld remote complies with protection class IP67. Backlighting in the handheld remote allows full and precise command selection even in the dark. The emergency stop switch provided can be used to initiate a remotely controlled emergency stop.

Power supply of the radio remote control

Our 868 MHz handheld remote controls are powered by standard AA or AAA batteries. The handheld remote can therefore last for 2500 hours on standby or 100 hours of continuous radio operation. The batteries can be replaced with the same type of rechargeable batteries. To conserve battery power, the handheld remote goes into standby mode after two minutes of inactivity.

The radio transceivers of our remote controls get the required energy directly from where they are installed. The 12V or 24V power supply for Sistematica radio receivers in vehicles, for example, comes directly from the on-board power supply.

Fields of application of the radio remote control

Sistematica radio remote controls have a wide range of applications. Anything that can be switched on or off electronically can be conveniently and wirelessly operated with a handheld remote control. For example, in the field of hydraulics, a handheld remote can be used to operate electric valves on slide valves or any functions powered by a hydraulic pump. In the automobile industry, hydraulics is standard. Radio control is also used in shipbuilding. Of course, purely electrical functions can also be operated with our radio remote control. This could be electric winches, work lights or a door drive system on various garage or warehouse doors.
