Description

4 NAMUR sensors, optocouplers, mechanical contacts or other operating elements can be connected to the isolator amplifier in an intrinsically safe way. The intrinsically safe inputs are safely galvanically isolated from the supply voltage and the outputs in accordance with EN/IEC 60079-11. Open and short circuits on the sensor lines are detected and signalled via an additional transistor output as group fault signal. LEDs display the output states.
