![ELX1058 | EtherCAT Terminal, 8-channel digital input, NAMUR, Ex i](https://multimedia.beckhoff.com/media/elx1058__web_preview.png)
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 states and any error states.
In addition to switches, incremental encoders with a NAMUR interface can also be connected. The configuration of the signal inputs for this can be set via software. 8 digital inputs are pre-set as standard. By choosing the appropriate configuration, up to 2 incremental encoders can be operated simultaneously with 2 digital input channels. You can select whether a positive or negative switching sensor is connected for each channel for the digital inputs. This allows NAMUR NCs and NOs to be integrated into the control system. Potential-free contacts can also be connected.
EtherCAT Terminals from the ELX series must always be operated in conjunction with the ELX9560 power supply terminal, which generates an electrically isolated output voltage (24 V EX) from the input voltage (24 V DC) to supply the downstream ELX terminals. If a repeat supply is required, an ELX9410 and an ELX9560 can be combined so that further ELX terminals can be connected in series. The ELX terminal segment must be terminated with an ELX9012 or two ELX9410s.
