Galltec L Series with analogue outputs
Product Descriptions
Economical transmitters of the L Series are primarily optimized for ambient room conditions and are very well suited to help control energy costs in HVAC and building automation applications. Thanks to their high-quality manufacturing, these transmitters can also be used in industrial settings under moderate conditions.
