TwinSAFE SC: Making standard signals usable for safety tasks

Distributed Clocks: the integrated time management system in EtherCAT

The EL5021-0090 EtherCAT Terminal is used for the direct connection of a measuring probe or encoder with sinusoidal, differential voltage output 1 VPP. Input frequencies of max. 250 kHz can be evaluated. The current counter reading can be zeroed (reset) or stored separately via the C track of the encoder, which is also called reference mark. The 5 V supply to the encoder is provided directly via the terminal connection points. The EL5021-0090 features amplitude and frequency error detection of the input signals.

 

The EL5021-0090 also supports TwinSAFE SC (TwinSAFE Single Channel). Thereby it is possible to make use of standard signals for safety tasks in any network or fieldbus.

 

Special features:

  • store, lock, set counter
  • diagnosis: frequency error and amplitude error of input signals
  • integrated frequency measurement
  • integrated 5 V DC encoder operating voltage

 

The analog input signal is processed, interpolated and made available as a 32-bit count value. The count value is a combination of the number of whole periods, max. 24 bits, and the value within one sine period, with max. 13 bit resolution. The EL5021-0090 also provides an internal frequency measurement. It also supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT distributed clocks (DC).
