Lightning/surge protector
The Model 8022 lightning/surge protection module provides 4-wire, multistage protection in a DIN rail package. It accommodates 4-wire networks used for data communications of RS-232-based signals or other signals whose amplitude falls within +15 to -15V. Protection is provided in three stages: the first is a high-capacity gas discharge tube to protect against the threat of very fast and excessive voltage transients; the second and third stages are 2-kW-rated semiconductor suppressors, which reac
