The 117 Series is simple to install and operate for alarm, safety and emergency shutdown applications where preserving process uptime, and protecting personnel and equipment are paramount. A hermetically sealed switch protects switch contacts from dust, water, corrosive gas, and other particulates. As an electromechanical switch, it can safely operate independently of the control system and switch reliably when called upon, free from potential communication errors or cyber concerns.
Typical applications that utilize the 117 Series include controlling rotating equipment – pumps, turbines, and compressors, and oil and gas separation systems
