EHG SL10 Process Controller and Safety Limit
 Watlow's new EHG SL10 process controller and safety limit integrates a heater, adjustable set point controller, high/low temperature alert, power switching device and a safety high temperature limit all in one package. This base unit controller also offers three upgrade modules: display module, communication module and display and communication module allowing you to purchase only what is required for your application. Plus, no technician is required for the installation of these upgrades, which creates a seamless, cost-efficient system.
In addition, the EHG SL10 is designed for easy integration with Watlow heaters simplifying engineering, reducing component count on new equipment and decreasing your cost of ownership. The EHG SL10 meets UL® 1998 and CE 60730 requirements.
