Surge protection devices

By Plant Engineering Staff May 2, 2007

The STC series of data/signal line surge protection devices, offered in a variety of application-specific voltages and packaging configurations, prevent transient voltages from interrupting data streams or damaging vulnerable electronic equipment. Using multi-stage hybrid circuitry based on gas tubes, silicon avalanche components and re-settable PTC fuses, STC series devices effectively address overvoltage transients to provide high-speed, high-energy protection to network signal lines entering or leaving control panels, such as PLCs, universal remote I/O, DeviceNet and Data Highway Plus. Other STC series models are designed to guard telecommunications and video surveillance systems from internally generated transients and noise.
