Compatible Operating Systems: ModBus
Supported Architectures: Ethernet base

The ATC-ETH-DIG-I/O is an Ethernet based Multi-Function I/O module that employs dual Altera Cyclone® FPGAs for maximum deterministic performance and I/O capability.

The module provides an Ethernet network interface for Digital I/O, Analog and Serial communication. Although it is fully functional as delivered, the User FPGA can be modified for custom bus implementations, which allows maximum flexibility and pre-processing capability for time-sensitive applications.

To communicate with the host, the ATC-ETH-DIG-I/O uses simple standard networking protocol – Modbus – that allows for control and data transfers.

The ATC-ETH-DIG-I/O interface include:

  • One GigE ports with ModBusTCP
  • Serial ports including a RS-232 console
  • Three Serial ports programmable via user FPGA with RS-232 / RS-422 / RS-485 interfaces
  • Thirty Six buffered general Purpose Input lines LVTTL level
  • Twelve buffered general Purpose output lines LVTTL level with 24ma drive
  • Four channels Low Side Open Drain Output with 1A Drive
  • Twelve Channels RS-422 Receive Channels with 120 Ohm termination resistor
  • Eight Channels RS-422 Transmit Channels
  • One Channel I2C interface
  • One Channel SPI interface
  • 8 Channels Analog to Digital 16 Bits converter for external voltage monitor
  • 8 Channels Analog to Digital 16 Bits converter for internal voltages monitor
  • Real time Clock battery backed
  • On board temperature monitor
  • Available in rugged, conduction cooled, extended temp -40°C to +85°C.
