NPEXB-H511L

Digital output isolated barrier. By switch signal controlling, transfers the wet contact signals from a safe area into current signals to a hazardous area, and drives field device like intrinsically safe valves, audible alarms, etc. It has backplane loop powered. The input and output is galvanically isolated from each other.
