Doehler & Haass DH-Rückmelder

The newly developed Doehler & Haass sensor replaces the previous Doehler & Haass occupancy detector. It takes over the most important features of its predecessor: 8 track sections, occupancy information in conjunction with all digital systems, adjustable release delay, updating capability. Unlike its predecessor, which only enabled the SX1 locomotive number feedback along with the FCC Digital Center and the Doehler & Haass Power Packs, the new transmitter now supports SX1 locomotive number feedback with almost all digital systems capable of SX1 data packets on the market Output track. In addition, DCC locomotive addresses can also be reported back by RailCom®-capable decoders if there is a cutout on the track. The detector 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 digital system of the competitors.
Product features and functions:
Eight-track occupancy detector, Suitable for two- and three-wire track systems, MOSFET technology enables parallel operation with unbalanced braking distances, Adjustable enable delay, usable in conjunction with all digital systems, allows the construction of an independent feedback system in parallel with the existing digital system Competitors).
Three operating modes: 1. Only occupancy report, 2. Occupancy message and SX1 locomotive number confirmation, Compatible with the previous D & H occupancy detector and DigiRail occupancy detector 8i, feedback of up to four locomotive addresses per track section, 3. Occupancy message, SX1 locomotive number confirmation and RailCom® feedback, feedback from Broadcast locomotive addresses (Channel 1), feedback from locomotive addresses (Channel 2), feedback of the CV values ??reported by the decoder, feedback of the actual speed reported by the decoder, feedback of the decoder signaled back signal quality, 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 state-of-the-art technologies, Galvanic isolation between SX bus connection and siding, Prepared for SX2 locomotive feedback, SX bus connection with DIN - and shielded RJ45 sockets (allows the cost favorable looping of the SX bus with Ethernet patch cables), updating capability of the feedback sensor.
