1. General
XPB Series ON-OFF Signal Input Isolated Barrier receives ON-OFF signal from the hazardous area, such as proximity switch, dry contact, voltage pulse , and outputs to the safe area after isolation. It restricts the energy from intrinsically safe port to hazardous area, insuring the system against explosion. It widely used in chemical industry, petroleum, natural gas, electricity, and other industrial fields. It is connected with all kinds of intrinsic safety instruments and used as the associated equipment of intrinsically safe explosion-proof system.
The product meets GB3836.1-2010 Explosive atmospheres - Part 1: Equipment-General requirements and GB3836.4-2010 Explosive atmospheres - Part 4: Equipment protection by intrinsic safety “i”. It has passed the test of China National Test Centre for Explosion Protect Electrical Products and obtained the Explosion-proof Certificate.
