1550 TCS Train Control Systems / AZL4 DCC Motor Control Decoder -- Fits ALL Z Scale Locos-4-Function DropIn Decoder (SCALE=Z) Part # 745-1550

The AZL4 DCC Motor Control Decoder is a top - notch 4 - function drop - in decoder designed for all Z Scale locomotives (Part # 745 - 1550). It has compact dimensions of 1.3” x .26” x 0.1” (33mm x 6.6mm x 2.54mm). With a continuous/peak of 1.3/2.0, it offers great performance. It has 4 total functions with a 100 mA function rating, 2 12V outputs, and 2 onboard LEDs. This decoder fits well in American Z Lines modern diesel chassis like SD70, SD70M, etc. It comes with built - in forward and reverse LEDs for easy, solder - free installation. The auto - adjusting BEMF ensures excellent slow - speed performance and hassle - free setup. It also features Back EMF Load Compensation for superior slow - speed control, Quiet Drive for noise - free motor operation, DC Mode for automatic DC power detection, Variable Momentum for custom acceleration curves, Incandescent Bulb Support, Function Remapping, Programmable Lighting Effects, Dimmable Brightness, and a Decoder Lock to prevent accidental programming.

Using this AZL4 DCC decoder is easy. First, make sure your locomotive is a Z Scale one. You can simply drop the decoder into the locomotive chassis, especially those of American Z Lines modern diesel locomotives like SD70 and GP9. Since it has built - in forward and reverse LEDs, there's no need for soldering during installation. For power, the decoder can automatically detect DC power, and you can configure the lighting effects in DC mode. You can use buttons 0 through 12 to control the lighting functions. When it comes to programming, you have 20 separate user - programmable lighting effects to choose from and can also set custom acceleration and deceleration curves. Regarding maintenance, keep it in a dry place. Avoid exposing it to extreme temperatures. If you're not using it for a long time, store it properly. Also, when programming, activate the decoder lock to prevent any accidental changes to the settings.
