The GR20 series, a new generation of remote I/O modules from Inovance, revolutionizes installation by being placed outside the cabinet for cost-effectiveness. Leveraging IO-Link, a pioneering standard I/O technology enabling sensor and actuator communication with controllers, it streamlines sensor wiring through three-wire grouping, reducing both costs and maintenance time. GR20 IO-Link sub-stations must be used with a GS20 IO-Link main station. Each IO-Link main station can be connected to eight IO-Link sub-stations, offering a preferred choice for external mounting solutions.
