TAS Plain (no Snubber)
TAS (Train Actuator Shield) with no "Snubber"
This model of the TAS is the simplest but has no "Snubber circuit" and, hence, can only reliably control non-inductive loads. That is, it may not work properly with electromechanical devices or when actuating a solenoid. It offers a prototyping area where you can add your own circuitry and implements components that respond to two command path signals on Arduino Uno digital pins 6 & 7. This is the least expensive TAS but, WARNING, it does not reliably control inductive loads. Be smart test it in your application and be ready to turn off power.

There are several versions of the Train Actuator Shield (TAS) but all work with a Sketch running in the attached Arduino Uno to act like a mechanical switch, turning on/off connected AC voltage (except the TAS Relay which can switch both AC & DC voltage). Features of each TAS version are described more fully in the TAS User Manual and Purchasing Catalog.
All versions of TAS are generic Arduino Uno Shields which can be used for anything you want (such as home automation). No trains are required. No TES is required.
This version is the TAS Plain. It has no "Snubber circuit" and, hence, cannot reliably control inductive loads. It handles command signals on Arduino Uno digital pins 6 and 7.
All images should be considered representative. That is, the PCB or color may change and components, logo, whatever… may be added, removed, revised, or moved. What you receive may look different – but it will work as described.
