The rIO Series Expands: New Relay Module for Advanced Industrial Control


The SIPRO EtherCAT I/O module family continues to evolve. Following the successful launch in early 2025, the rIO series welcomes a new strategic component: the rIO_RL4 module, designed to manage 4 relay outputs, and set to be available for sale in the coming weeks


Performance and Versatility

The rIO_RL4 module integrates 4 electromechanical relays designed to control actuators up to 6 Amps at 250 Vac, ensuring reliability even in the most demanding applications. Each relay offers a complete configurability of contacts – normally open (NO), normally closed (NC) and common (COM) – providing maximum flexibility in any control architecture.

Instant Diagnostics for Superior Efficiency

Like other modules in the rIO series, the rIO_RL4 features an intelligent visual diagnostic system: identification LEDs for immediate recognition of the board type and dedicated indicators for the status of each relay. This detail simplifies testing and maintenance operations, reducing setup and intervention times.

Looking Ahead

The release of the rIO_RL4 is not a point of arrival but part of a broader roadmap. SIPRO is already finalizing the development of new modules, including rIO_SSI for 2 serial absolute SSI encoder readings – a direct response to market demands for increasingly precise and reliable positioning solutions.


This ability to anticipate and quickly respond to industry needs confirms SIPRO’s position as a leading technology partner in industrial automation.
