The RIO-574x0 EtherCat slave I/O controller offers digital and analog I/O to be used remotely in an EtherCat automation system. Although the controller can be used with any generic EtherCat master, it is designed to integrate into an EtherCat system with the company’s DMC-500x0 EtherCat master. The controller has 16 opto-isolated digital inputs and 16 high-power (500-mA sourcing) opto-isolated digital outputs. It includes eight analog inputs (4-20-mA option available) and eight analog outputs, both configurable in the ranges of 0-5, 0-10, ±5 or ±10 V (12-bit standard with 16-bit option available). All I/O are accessible via screw terminals. LED indicators are provided for all digital I/O points.
