<p>The RB40 utilizes all the trusted attributes of the previous Redundancy Bus series along with adding new features to meet the needs of an ever-growing range of users.</p><p><br></p><h4><b>The upgraded redundancy hub</b></h4><p>Previous redundancy bus models offered a dual-power with a dual-receiver design, the RB40 allows the user to use a triple redundancy by adding a multiplex port (RX3 IN / SBUS Out) and uses a set of standard XT60 plugs which provides a safe and efficient way to provide power.</p><p><br></p><h4><b>Up to 24 PWM channels with overload protection</b></h4><p>The RB40 supports connecting up to 24 high-voltage servos with overload protection added to each output channel. Eight of the channels (CH1-8) are equipped with current sensors.</p><p><br></p><h4><b>The diversified sensors</b></h4><p>The RB30 is an extensive sensor module with a built-in gyroscope that supports model stabilizing functions and includes other diversified telemetry feedback like the voltage, power consumption, altitude, and a lot more. It can be used as an alternative to using a GR or S series receiver.</p><p><br></p><h4><b>NFC Switch &amp; Automatic data logging functions</b></h4><p>The non-contact NFC switch is an external device that enables the power to be switched on/off on command without the need to plug/unplug the battery connections. Once power is connected, the black-box function is automatically activated and immediately starts recording the data.</p><h4><b><br></b></h4><h4><b>Menu scroll button, LCD screen &amp; CNC case</b></h4><p>The RB40 features a display screen that is comparable in size to one found on the X-Lite series radio. Navigating and configuring telemetry data is even more convenient thanks to the scroll button. Even considering all these features while maintaining durability, the RB40 weighs only 260 grams thanks to the hybrid design of carbon fiber and aluminum materials.</p><p><br></p><h4><span style="font-weight: bold;">FEATURES:</span></h4><p><br></p><ul style="list-style-position: initial; list-style-image: initial; margin-right: 0px; margin-bottom: 0px; margin-left: 35px; padding: 0px;"><li style="margin: 0px 0px 6px;"></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Dual Power &amp; Triple Receiver Guarantee</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">High-voltage Servo Supported (Up to 24 PWM servos)</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Overload Protection on Each Channel</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Channel 1 – 8 with Current Detection</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Supports Stabilization Function with Built-in Gyroscope Sensor</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Multiple configuration methods (Lua script and FreeLink)</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Compatible with FrSky S.Port products</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Various S.Port Telemetry Feedbacks (Voltage, Current, Power Consumption, etc.)</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Black Box Data Record Function</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">Non-contact NFC Switch Function</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">LCD Screen with Menu Scroll Button</span></li><li style="margin: 0px 0px 6px;"><span style="font-size: 14px;">CNC Aluminum &amp; Carbon Fiber Case</span></li></ul>
