ZX21TCA - high-speed-controller with digital and analog I/O and EtherCAT

The ZX21TCA high-speed controller extends the ZX21 family with fast analog inputs and outputs with processing times of less than 10 µs. In addition, an interface for an SSI encoder is available, which can alternatively be configured as two digital inputs or outputs with TTL differential signal.

With integrated EtherCAT-SLAVE single control systems can be integrated in higher systems.

This means:

  • Direct, simple integration in higher control systems
  • No additional hardware is necessary
  • High-speed data transfer


The visualisation is possible with the help of ZANDER MVisio HMI via PROFINET
