The K0D8-E is a drop-in decoder for Kato N Scale engines: E5 and E6. It has 8 functions with built-in onboard resistor for LED’s, 1 onboard superbright, Sunny White LED with medium length leads. Note: Four of the functions (F1-F4) have onboard resistors for LED’s and 1.5v bulbs. The remaining two hardwire functions (F5-F6) output at 12v and will need external resistors if you plan to use LED’s or 1.5v bulbs. Included is our auto-adjusting BEMF for outstanding slow speed performance and hassle free set up. Also includes Quiet Drive for super quiet engine performance.
