Three wire safety barrier/Xunpeng XPB-G

XPB seriesAnalog input safety barrier2-wire, 3-wire, or 4-wire transmitters that can be connected to hazardous areas can provide working power to the hazardous area. The sampled transmitter output signal is converted into a linear signal for the user and output to the safe area. The safety barrier limits the energy entering the hazardous area from the intrinsic safety terminal, ensuring the intrinsic safety and explosion-proof of the system. The product is widely used in various industries such as chemical, petroleum, metallurgy, natural gas, and power. It is connected to various intrinsic safety instruments and used as an associated equipment for intrinsic safety explosion-proof systems.

The product complies with GB3836.1-2010 Explosive Atmosphere Part 1: General Requirements for Equipment and GB3836.4-2010 Explosive Atmosphere Part 4: Equipment Protected by Intrinsic Safety Type "i". It has passed strict inspection and testing by the national explosion-proof testing agency and obtained an explosion-proof certificate.
