EPX3184-0092 | EtherCAT Box, 4-channel analog input, current, 4…20 mA, 16 bit, single-ended, M12, HART, Ex i, TwinSAFE SCNew

The EPX3184-0092 analog EtherCAT Box allows intrinsically safe HART-capable field devices from hazardous areas of zones 0/20 and 1/21 to be directly connected. It supplies measuring transducers located in the field and transmits their analog measuring signals to the automation device under electrical isolation. The EtherCAT Box indicates the status of the HART communication via LEDs and signals any communication errors.

The HART (Highway Addressable Remote Transducer) protocol enables two-way communication through digital data transfer via the analog 4...20 mA wiring. In this way, further data can be exchanged with the field device via the superimposed digital signal, in addition to the analog current signal.

HART communication can also be used for the FDT/DTM concept. The TwinCAT FDT Container enables field device DTMs to be directly integrated into TwinCAT Engineering. This means that field device configuration and diagnostics are already available in the development environment.

With the aid of the TwinSAFE SC technology (TwinSAFE Single Channel) it is possible to make use of standard signals for safety tasks in any network or fieldbus. To do this, EtherCAT I/Os from the areas of analog input, position measurement or communication (4…20 mA, incremental encoder, IO-Link, etc.) are extended by the TwinSAFE SC function. The properties typical for the signals and the standard functions of the I/O components are retained.

The data from the TwinSAFE SC components is fed via a TwinSAFE protocol to the TwinSAFE Logic, where it can be used in the context of safety-relevant applications. Detailed examples confirmed/calculated by the TÜV SÜD for the correct application of the TwinSAFE SC components and the respective normative classifications can be found in the TwinSAFE application manual.
