The EL1262-0050 digital input terminal acquires the fast binary 5 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes. The signals are sampled with a configurable, integer multiple (oversampling factor: n) of the bus cycle frequency (n microcycles per bus cycle). For each bus cycle, the EtherCAT Terminal generates a process data block that is transferred collectively during the next bus cycle. The timebase of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. This XFC procedure enables the temporal resolution of the digital input signals to be increased to n times the bus cycle time. The switching thresholds of the input circuit are based on the CMOS level: Signal voltage "0" < 0.8 V, signal voltage "1" > 2.4 V. The 5 V supply voltage can be generated by the EL9505 power supply terminal and fed into the power contacts.

 

Special features:

  • 5 V inputs
  • suitable for particularly fast signals due to very low input delay
  • synchronized operation through distributed clocks XFC technology possible
  • multiple sampling of a process data through oversampling
