ELX1054 - Introduction

Fig. 5: ELX1054 - 4-channel digital input terminal for NAMUR sensors, Ex i

The ELX1054 digital input terminal acquires signals from NAMUR field devices according to EN 60947-5-6.

The sensors are supplied with a voltage of 8.2 V and return a diagnosable current signal. In this way, a wire

breakage or short-circuit can be detected in addition to the switching state. The LEDs indicate signal or any

error states, channel by channel. The sensor supply is equipped with voltage and current limitation for each

channel.

Using the DIP switch [} 30] on the side, it is possible to select channel by channel whether a positive

switching or negative switching sensor is to be connected. Thus, no changes to the PLC are required for the

connection of both NAMUR break contacts or make contacts.
