Use the Trak-DTT (Track-DeTector Timer) block detector to switch on or off anything around your layout for a duration of 1-45 seconds. Trak-DTT current detector activates its on-board relay when current is detected. The relay relaxes after an adjustable time between 0-45 seconds. The timer functionality is selectable, beginning either immediately when current is sensed or after the current is removed. The detector waits until current is removed for a few seconds before allowing detection once again. Current is detected by passing a wire through the sense coil on the board.
Add a station stop easily to your model train layout with the Trak-DTT and a ballast lamp (item #538) or use the Trak-DTT as a "short block" detector with fixed timed occupancy. Simply create an isolated section of track to trigger the Trak-DTT, change a few wires, and you have it. Use the Trak-DTT to operate your solenoid type switches or semaphores. You can also use the TrakDTT as a momentary power supply for all your solenoid switch machines on your layout. The TrakDTT combines two functions in one unit.
The small block detector circuit board contains a jumper for dual functionality (see below) and a time frame adjustment dial.
