        HAI was formed in 1985 by founders Tom Pickral, Brian Yokum, and Jay McLellan. Company profitability was reached just eight years later in 1993. Since that time, earnings have been reinvested into product research and development. A worldwide network of distribution partners including thousands of dealers in over 80 countries is responsible for HAI's global presence today. HAI's corporate headquarters is located in New Orleans, Louisiana..A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called protective relays
