Doehler & Haass feedback - digital system (Gen2)

Doehler & Haass feedback - digital system (Gen2)

 

Technical details

Feedback detector

Product features and functions
Occupancy detector for eight track sections
Suitable for two- and three-wire track systems
MOSFET technology enables parallel operation with asymmetric braking sections
Adjustable release delay
Can be used in conjunction with all digital systems
Allows the construction of an independent feedback system parallel to the existing digital system (even if this comes from competitors)
Three operating modes:
1. Occupancy detection only
2. Occupancy detection and SX1 locomotive number feedback
Compatible with the previous D&H occupancy detector and Digirail occupancy detector 8i
Feedback from up to four locomotive addresses per track section
3. Occupancy report, SX1 locomotive number feedback and RailCom® feedback
Feedback of broadcast locomotive addresses (Channel 1)
Feedback of locomotive addresses (Channel 2)
Feedback of the CV values reported back by the decoder
Feedback of the actual speed reported back by the decoder
Feedback of the track signal quality reported back by the decoder
Adjustable sensitivity (400µA, 2mA, 10mA)
Simultaneous evaluation on all eight track sections in both polarities (no "round robin")
Very low voltage drop through the use of the latest technologies
Galvanic isolation between SX bus connection and track connection
Prepared for SX2 locomotive address feedback
SX bus connection with DIN and shielded RJ45 sockets (enables cost-effective Looping through the SX bus with Ethernet patch cables)
Updating capability of the feedback device
The update (the firmware download from the Internet is free) is possible when the feedback device is installed in the system (no need to open the housing) and is carried out via the FCC digital control center.
The newly developed feedback device replaces the previous occupancy detector. It takes over the most important properties of its predecessor: 8 track sections, occupancy detection in conjunction with all digital systems, adjustable release delay, update capability. Unlike its predecessor, which only enabled SX1 locomotive number feedback in conjunction with the FCC digital control center and our power packs, the new feedback device now supports SX1 locomotive number feedback with almost all digital systems that are able to output SX1 data packets on the track. In addition, DCC locomotive addresses can also be reported back by RailCom®-capable decoders, provided there is a cutout on the track. The feedback device has a galvanic isolation between the track sections and the SX bus connection and thus enables, for example, the construction of an independent feedback system together with a competitor's digital system.
