Descripción
The ELX1052 digital input terminal allows the direct connection of intrinsically safe field devices located in hazardous areas classified Zone 0/20 or 1/21 and acquires their signals in compliance with IEC 60947-5-6. The sensors are supplied with a voltage of 8.2 V and return a diagnosable current signal. In this way wire breakage or short circuit can be detected in addition to the switching state. The LEDs represent the signal states or any error states.
