Doehler & Haass FH18A - Vehicle function decoder (Gen2)

Doehler & Haass FH18A - Vehicle function decoder (Gen2)

 

Technical details

Vehicle function decoder FH18A for SX1, SX2, DCC and MM (2nd generation)

Product features and functions
For optional operation with conventional DC driving device, digital systems SelecTRIX 1 and 2 or according to DCC format
The switchover between analogue and digital operation takes place automatically
In digital operation, the last programmed system is used (it is not switched over 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
Internal 127 speed levels
Block route operation with simple diodes in digital operation
Light and function outputs (partially) dimmable and can be activated analogously
Shunting gear
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 function decoder FH18A 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 (loco address feedback in DCC operation, RailCom®).

For SX1 programming, a SUSI module or . to remove a connected buffering. 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.

Our proven vehicle function decoder FH18A is now available in the 2nd generation after complete product maintenance and offers many advantages:
Greatly reduced dimensions (9 .7 * 8.9 * 2.8 mm)
Higher total load capacity (1.5 A)
Approximately two and a half times the buffer capacity (therefore longer contact faults can be overcome without data loss)
