This 1-Channel High-Power Reactor Relay Controller makes it easy for sensors to directly control an external light, motor, and other high-power electrical device based on environmental actions or conditions. Use external sensors to activate the on-board high-power relay for a pre-set time period. Use a computer to configure the Reactor. Once configured, Reactor works stand-alone, or in combination with a PC, depending on your application requirements. Reactor is compatible with many popular communication technologies, providing a upgrade path should your needs change in the future. Mechanical Relays are an ideal for choice for most users because of their long-life and low cost. Inductive loads such as Motors, Valves, Pumps, Solenoids, and Large Transformers (including Fluorescent Lighting) will require external induction suppression capacitors to reduce interference to acceptable levels.
