These LonMark actuators provide communication via LON. In addition to the network capabilities the different versions offer two digital inputs or two digital outputs which can be used for a more application oriented actuator integration. For example, two digital outputs can be used to set the ventilation speed or a floating actuator can be connected to provide LON capabilities to standard actuators to reduce installation cost. The actuators work with standard SNVTs to provide interoperability with controllers based on LonWorks technology. The ML7420G is especially designed to provide LonMark capabilities together with the well known HVAC valve offering. They are employed in electronic temperature control system using hot, steam and/or cold water as the controlled medium. The ML7420G actuators are suitable for Honeywell Excel series controller as well as for any other controller based on the LonWorks technology. Using standard Echelon configuration tools, the actuator can be configured with job specific settings. To simplify start up and maintenance we provide plug Ins which will benefit in a reduced installation time. These actuators fit in commercial and in semi industrial applications and offer application oriented features as well as a rugged and stable design.
