FrSky RB-40 Dual Power Triple Receiver Redundancy Hub

FrSky RB-40 Dual Power Triple Receiver Signal Redundancy Module with Stabilisation Function & NFC Power Switch

The FrSky RB-40 is a switchboard module that can operate 3 receivers and dual power inputs to provide you with total peace of mind when flying your models. The RB40 utilises 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.

The upgraded redundancy hub
Previous redundancy bus models offered a dual-power with a dual-receiver design. The RB-40 allows the user to use a triple redundancy by adding a multiplex port (RX3 IN / SBUS Out). You can even mix frequency bands, so for example 2.4GHz ACCESS and the 900MHz R9 System for even greater reliability. Power input is via a set of standard XT60 plugs.

Up to 24 PWM channels with overload protection
The RB-40 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

The diversified sensors
The RB-40 is an extensive sensor module, aside from its built in sensors that can monitor voltage and power consumption, there’s support for FrSky’s Smart Port system for connecting many different telemetry sensors that can help you monitor your flight in great detail. There is also a SD card slot, which can be used as a black box for data logging.

Two Output BECS
The RB-40 supports a voltage input of 11-26V and provides two voltage regulated SBEC outputs DC 5-8.4V via twin XT60 sockets. The output voltages can be adjusted directly from your FrSky transmitter via a LUA-script or via FrSky FreeLink, which makes the setup simple.

Built In Stabiliser
The RB-40 has a built-in gyroscope that supports model stabilising functions, so it can be used as an alternative to using a GR or S series receiver.

NFC Switch & Automatic data logging functions
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.

Menu scroll button, LCD screen & CNC case
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.
