ELXxxxx | 防爆（Ex i）
带本质安全型输入/输出的 ELX 系列 EtherCAT 端子模块能够直接连接位于危险区 0/20 区中的现场设备。
ELX2008 | EtherCAT Terminal, 8-channel digital output, 24 V DC, 30 mA, Ex i
The ELX2008 digital output terminal enables the direct connection of intrinsically safe actuators located in hazardous areas classified zone 0/20 or 1/21. The ELX2008 supplies an output voltage of 24 V DC and a maximum output current of 30 mA per channel. The signal state of each channel is indicated by a light emitting diode.
ELX3158 | EtherCAT Terminal, 8-channel analog input, current, 4…20 mA, 16 bit, single-ended, Ex i
The ELX3158 analog EtherCAT input terminal allows the direct connection of intrinsically safe field devices located in hazardous areas classified zone 0/20 or 1/21. It supplies measuring transducers located in the field and transmits their analog measuring signals electrically isolated to the automation device. With a technical measuring range of ±107 % of the nominal range, the terminal also supports commissioning with sensor values in the limit range and evaluation according to NAMUR NE43. The error LEDs indicate an overload condition and wire breakage.
