Doehler & Haass FH22A-4 - Vehicle function decoder

 

Technical details

Vehicle function decoder FH22A for SX1, SX2, DCC and MM

Product features and functions
For optional operation with conventional DC driving devices, digital systems according to SelecTRIX 1 and 2 or according to DCC format
Switching between analog and digital operation is automatic
In digital operation, the last programmed system is used (it does not switch automatically!)
SelecTRIX 1 31 speed steps, 100 addresses
SelecTRIX 2 127 speed steps, 10,000 addresses, 16 additional functions
DCC short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed steps
Internal 127 speed steps
Block section operation with simple diodes in Digital operation
Light and function outputs (partially) dimmable and can be activated analogue
Shunting
Light and track connections can be exchanged electronically
All function outputs are freely programmable
Temperature protection
Reset function for DCC and SX2
Decoder can be updated

The vehicle function decoder FH22A supports braking with asymmetrical digital voltage (four diodes in series and one diode antiparallel, Lenz ABC), slow travel (with suitable brake modules) and bidirectional communication (locomotive address feedback in DCC operation, RailCom®).
