ECAT-2074A – a 4-channel EtherCAT module for controlling BISS-C/SSI absolute encoder

01 March 2024 Product News

ICP DAS has introduced an EtherCAT module for absolute encoder control - ECAT-2074A.

ECAT-2074A has four independent channels capable of operating with a high degree of autonomy. This device supports two serial data interfaces: SSI (Serial Synchronous Interface) and BiSS-C (BiSS Continuous Mode), providing flexibility and versatility in information exchange.

In addition, the ECAT-2074A can operate at a maximum transmission frequency of 10 MHz and receiving data with a maximum data width of 48 bits (including error, warning and CRC bits in BiSS-C mode), which ensures reliable and accurate data transmission.

This device is equipped with automatic cable delay compensation function in BiSS-C mode, ensuring stable and efficient operation in various environments. It should also be noted that the ECAT-2074A allows the use of cables up to 70 meters long, providing flexibility in placement and connection of the device.

  • Key features of the new model:
  • Four channels, 48-bit absolute encoder master
  • Transmission Interface: BISS-C, SSI
  • Data encoding mode: binary, gray (Gray)
  • The CRC generator polynomial can be customized, with a maximum value within CRC-8
  • Support CRC bit inversion
  • Maximum pulse transmission frequency: 10 MHz
  • Simultaneous data acquisition from each channel
  • EtherCAT:
    • 2 x RJ-45
    • Support for Free-Run and Distributed Clock (DC) operating modes
