Product Isolated Barrier NPEXA-K511

NPEXA-K511

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.

Insulation resistance ≥ 100 MΩ (Input /Output/Power supply)
Operating conditions
Operation temperature -40 ℃ ~ +70 ℃
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, ǀ, ⅡA, ⅡB, ⅡC, ⅢC, T4 ~ T6. When the apparatus used in zone 2, please comply with the special conditions of use in the instructions.
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
Safe state de-energized
