The Digitrax SE74 is the signal and turnout decoder that ties a working signal system to your LocoNet. It drives signal masts, throws four turnouts, reads eight input lines for sensors and local push buttons, and stores eight routes of eight entries each - which means interlockings and crossovers can be set from a single command instead of one turnout at a time. Signalling your layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. Features Fully connectorized installation - signal driver cables and turnout leads plug in, so a signal bay can be built on the bench and dropped under the layout. Four turnout outputs, configurable for solenoid machines (Peco, Atlas, Kato) or slow-motion machines such as the Tortoise. 8 input lines for block detectors, sensors and local control buttons at the fascia. 8 system routes with 8 entries each - throw a whole crossover or interlocking from one command. Optional DCC 9-aspect control mode, including Lunar aspects, for prototypical signalling. Setup via option switches or LocoNet programming, with Series 7 style configuration from a DT602 throttle. More Information Brand Digitrax Item Number SE74 Product Type DCC Signal and Turnout Decoder Scale All scales Turnout Outputs 4 - solenoid or slow-motion Input Lines 8 Routes 8 routes x 8 entries Signal Aspects Up to 9-aspect DCC mode including Lunar Connection LocoNet, connectorized signal driver cables Condition New FAQ What else do I need to get signals running?The SE74 plus signal masts and a way to carry the connections to them. Most installs use a Signal Driver Cable Kit (SDCK) for the ribbon cable and sockets, plus mast bases and mounting hardware. You also need occupancy detection - the SE74 displays aspects, it does not detect trains on its own. Can it drive slow-motion turnout machines?Yes. The four turnout outputs are configurable for either solenoid machines such as Peco, Atlas and Kato, or stall-motor machines such as the Tortoise. What are routes and why do they matter?A route sets several turnouts at once from a single command. With eight routes of eight entries you can line an entire crossover or interlocking with one button press instead of throwing each point individually. Do I need a Digitrax command station?Yes for full configuration - the SE74 is a LocoNet device and is set up over LocoNet, with the most convenient programming from a DT602 throttle.
