NEWPWR SIL3 NPEXA-C511 Digital input isolated barrier
Digital output isolated barrier. By switch signal controlling, transfers the dry 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 needs an independent power supply. The input, output, and power supply are galvanically isolated from each other.
