NEWPWR SIL3 NPEXA-C511 Digital input isolated barrier

NEWPWR NPEXA-C511 Digital input isolated barrier

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. The normal output sate and line fault detection function can be set with the DIP switch. The input, output, and power supply are galvanically isolated from each other.

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
