Overview

The ELX1058 digital input terminal allows intrinsically safe NAMUR field devices installed in hazardous zone 0/20 and 1/21 areas to be connected directly and acquires their signals in accordance with IEC 60947-5-6. The sensors are supplied with a voltage of 8.2 V and return a diagnosable current signal. A wire break or short circuit can thus be detected in addition to the switching state. The LEDs display the signal...
