Doehler & Haass DH18A - Vehicle decoder (Gen2)

Doehler & Haass DH18A - Vehicle decoder (Gen2)

 

Technical details

Vehicle decoder DH18A for SX1, SX2, DCC and MM (2nd generation)

Product features and functions
For optional operation with digital systems according to SelecTRIX 1 and 2 or according to DCC format
In digital operation, the last programmed system is used (it is not switched automatically!)
SelecTRIX 1 31 speed levels, 100 addresses
SelecTRIX 2 127 speed levels, 10,000 addresses, 16 additional functions
DCC Short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed levels
Latest generation load control, resulting in particularly soft control behavior
Various control variants for optimal adaptation the motor
Internal 127 speed levels
Adjustable motor frequency (low frequency, 16 kHz, 32 kHz)
Block route operation with simple diodes in digital operation
Light and function outputs dimmable
Shunting gear
Motor, light and track connections can be exchanged electronically
All function outputs are freely programmable
Temperature protection
Reset function for DCC and SX2
Update capability of the decoder
The vehicle decoder DH18A supports braking with asymmetrical digital voltage (four diodes in series and one diode anti-parallel, Lenz ABC), slow travel (with suitable brake modules) and bidirectional communication (locomotive address feedback in DCC operation, RailCom®).

For the SX1 -programming, a SUSI module connected to the supply voltage (VS) or a connected buffering must be removed. It is sufficient to interrupt the supply voltage (red wire for SUSI) for the time of SX1 programming. The SX2 or DCC programming is not affected by this.

The proven vehicle decoder DH18A is now available in the 2nd generation after product maintenance has been completed and offers many advantages:
Greatly reduced dimensions (9 .7 * 8.9 * 2.8 mm)
Higher overall load capacity and higher motor current (1.5 A)
Approximately two and a half times the buffer capacity (therefore longer contact faults can be overcome without data loss)
