Beckhoff ELX3181
ELX3181 | 1-channel analog input terminal 4…20 mA, single-ended, 16 bit, HART, Ex i
Description
The ELX3181 analog input terminal allows the direct connection of intrinsically safe HART-capable 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. The HART protocol (Highway Addressable Remote Transducer) enables two-way communication through digital data transfer via the analog 4…20 mA wiring. The TwinCAT FDT container enables the integration of field device DTMs into TwinCAT Engineering, so that the device configuration and diagnostic functions are available directly within the development environment. The EtherCAT Terminal indicates the signal state by means of light emitting diodes. Error LEDs signal overload and wire breakage, in addition to which LEDs provide information about the state of the HART communication and indicate any communication errors.
