EL5032-0090 | TwinSAFE SC: 2-channel EnDat 2.2 interface

The EL5032-0090 EnDat 2.2 EtherCAT Terminal is used for direct connection of two encoders with EnDat 2.2 interface. The EL5032-0090 enables reading of position values, diagnosis encoder data, internal and external temperature values and the electronic identification plate. With the electronic identification plate all measuring device-specific information is directly available. The position value is output with up to 48 bits, depending on the resolution of the connected measuring device, and transferred to the controller. The position value is output with up to 48 bits, depending on the resolution of the connected measurement device, and transmitted to the control system. Safety-relevant data processing by the TwinSAFE Logic, however, is only possible for 32-bit position values. If the encoder supplies values other than 32 bit values, it is possible to define for the EL5032-0090 whether higher-value or lower-value bits are to be included in the telegram sent to the TwinSAFE Logic.

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.
