The YD6016RB-Cs is designed to work with the ROCO z21 and Z21 on the R-Bus port.
 
Our standard current-sensing feedback module with RBus / XBus Interface
It presents:
    16 current-sensing detectors, arranged in two independent blocks of 8, each with their own Common
    2 Amp continuous current per detector, 8 Amps in total combined over the 16 detectors on the whole module
    5 Amp short duration overload (100ms) capable per detector.
    1mA current sensitivity
    Capacitive input filter on every input, to suppress noise on long cables and track-sections
    Configurable on- and off-delay setting for each input for optimal de-bouncing in case of non optimal wheel-track contact
    Every input individually configurable for various actions like feedback, turnout toggle, turnout throw, turnout close
    Every input individually configurable for turnout-address
    ES-IN-Link for direct connection of up to 4 additional YD6016ES modules (effectively creating a 80 input RBus module)
    ES-IN-Link connection to other ES-Link enabled modules for module-configuration
    ES-IN-Link connection to YD9101 for web-based configuration
    USB connection with one Virtual COM port for the YD.Command protocol
    Firmware updatable over USB
    Power supply directly from RBus / XBus ( or USB for easy configuration and updating on a PC )
