NPEXA-C5111

Digital input isolated barrier, it converts switch or proximity detector signals (dry contact or NAMUR) from a hazardous area into relay signals to a safe area by isolation. Operation mode, output 2 function and the input circuit fault detection function can be set with the DIP switch. The input, output, and power supply are galvanically isolated from each other.

Dielectric strength ≥ 3000V AC (intrinsically safe side / non-intrinsically safe side); ≥ 1500V AC (Power supply /non-intrinsically safe side)
Insulation resistance ≥ 100 MΩ (Input /Output/Power supply)
Operating conditions
Operation temperature -20 ℃ ~ +60 ℃
Storage temperature -40 ℃ ~ +80 ℃
Suitable location Mounting in safe area, and connected to the intrinsic safety apparatus in hazardous area zone 0, zone 1, zone 2, ⅡA, ⅡB, ⅡC, T4 ~ T6
State
LFD function When input current ≤ 50μA, considers the input line breakdown, the output relay de-energized. If input current ≥ 6.5mA, considers the input circuit short-circuit, the output relay de-energized, the indicator red flashing
