Beckhoff ELX3202-0090 | EtherCAT Terminal, 2-channel analog input, temperature

The ELX3202-0090 analog input terminal allows the direct connection of

RTDs located in hazardous areas classified zone 0/20 or 1/21.

The circuitry of the ELX3202-0090 can operate sensors with 2-, 3- and

4-wire technology. Linearization is carried out over the entire freely

selectable temperature range. By default the terminal is set to Pt100

sensors with 3-wire technology. The ELX3202 0090 terminal indicates

signal state and sensor malfunctions (e.g. wire breakage) by means of

LEDs.

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. TwinSAFE SC I/Os differ optically from standard I/Os by a

yellow stripe on the front of the housing.

The TwinSAFE SC technology enables communication via a TwinSAFE

protocol. These connections can be distinguished from the usual secure

communication via Safety over EtherCAT.

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.
