The Walthers 942-111 Distribution Block is a great addition to your layout control system. It simplifies electrical connections from the power supply to up to 8 switch machines. It has a built-in barrel connector for quick connection to a 2 Amp 12V Filtered DC Power Supply (949-110, sold separately). You can use screw terminals to connect a second Distribution Block (sold separately) or DCC power input. There are 8 matching position inputs/outputs for easy configuration with various devices like CMRI, stationary DCC decoders, microcontrollers, Arduino, and Raspberry Pi (each sold separately). It comes with two power extension cables and four benchwork mounting screws. The Walthers Layout Control System offers a low-cost solution for easy turnout control for HO, N, Z, S, and O Scale layouts. It's expandable, works with DCC- or DC-power, and uses plug-and-play servo-style wiring with connectors, so no soldering is needed. There are two styles of cables available separately to expand your wiring. All items come with user-friendly instructions, and appropriate drilling templates for easy mounting on your layout or fascia. You can easily build a complete control system using combinations of the system components like a servo-based slow-motion Switch Machine, Power Distribution Block, LED panel indicator-control pushbutton switches, add-on system cabling, a 2-amp 12V Filtered DC Power Supply, and a three-piece drill set.

Using the Walthers 942-111 Distribution Block is quite easy. First, connect it to your power supply using the built-in barrel connector. You'll need to buy the 2 Amp 12V Filtered DC Power Supply separately. Then, you can connect up to 8 switch machines to simplify your electrical connections. If you want to expand, use the screw terminals to connect a second Distribution Block or DCC power input. You can also use the 8 matching position inputs/outputs to connect with other devices like CMRI or Arduino. Just remember that these devices are sold separately. The block comes with two power extension cables and four benchwork mounting screws for easy installation. When it comes to maintenance, keep it in a dry place. Avoid getting it wet or exposing it to extreme temperatures. Check the connections regularly to make sure they are tight. If you have any issues, refer to the user-friendly instructions that come with the product. And don't forget to use the drilling templates for proper mounting on your layout or fascia.
