Description

Taco Switching Relays combine clearly labeled PC board layouts with advanced features that allow for total system customization. Whether using basic priority switching, or add-on power controls, the job is made easy.

All switching relays are UL listed, and are compatible with conventional and programmable thermostats. For those larger jobs, the -EXP Switching Relays can be expanded up to 120 zones (20 zoning panels) with priority. Taco Switching Relays are available in one, two, three, four, and six zones.
