2-Wire RS485 Surge Protector (Industrial / Passive) – CommFront

The SPD-485-1 is a passive, rugged, industrial-grade, 2-wire RS485 surge protector that can be used to limit the voltage surges and spikes introduced to the RS485 data lines. This industrial RS485 surge protector features 3-stage surge protection – Gas Discharge Tubes (GDT), protection resistors, and Transient Voltage Suppressors (TVS) - for maximum protection. The SPD-485-1 is designed to connect in series to the input of the protected equipment; when a high-voltage surge is introduced into the input, the GDT conducts electric current after becoming ionized, which in turn discharges the high-voltage surge to the earth ground. The excessive voltage will be further clamped to a safe range that the equipment can accept by the TVS. This industrial 2-wire RS485 surge protector features passive circuitry designs and thus requires no external power; it supports data rates up to 10Mbps and can be used
