Key takeaways
- Mouser announced on August 27, 2026 that it is stocking Banner Engineering’s RSio Remote Safe I/O Block.
- The block is designed for CIP Safety systems and combines six safety-input channels with two configurable output channels.
- Each of the six inputs can support an ISD chain of up to 32 compatible devices, for up to 192 devices per block.
- Configuration is performed in Rockwell Automation Studio 5000 using Banner’s supplied EDS file; integrators should still validate the complete safety function and application-specific wiring.
- Two power-connection versions are available: Mini power with up to 10 A pass-through and M12 L-Code with up to 16 A pass-through.
Distributor availability is confirmed
Mouser Electronics announced on August 27, 2026 that it is now stocking Banner Engineering’s RSio Remote Safe I/O Block. The availability announcement is specifically relevant to machine builders, controls engineers and maintenance teams designing or updating distributed safety systems around CIP Safety networks. ([au.mouser.com](https://au.mouser.com/en/newsroom/publicrelations-banner-rsio-remote-safe-io-2026final/))
Banner had already published RSio product documentation earlier in 2026, so the Mouser item is a distribution-availability development rather than the initial introduction of the I/O family. Banner’s English product manual carries a January 30, 2026 publication date.

Distributed safety I/O with ISD diagnostics
RSio is a remote safe I/O block for CIP Safety systems that incorporates Banner’s In-Series Diagnostics (ISD) technology. Its core I/O arrangement consists of six configurable input channels and two configurable outputs. The inputs can accommodate dry-contact or solid-state safety devices, ISD connections and standard control signals; the outputs can be used for safety-rated or standard applications, subject to the design and validation of the overall safety function. ([info.bannerengineering.com](https://info.bannerengineering.com/cs/groups/public/documents/literature/245780.pdf?utm_source=openai))
For ISD-capable installations, each input can support up to 32 enabled devices in a chain, yielding a stated maximum of 192 devices across the six inputs. The practical benefit is more precise identification of the device or connection associated with a stop or fault condition, without requiring every field device to return individually to a cabinet-mounted safety controller.

Where the architecture may fit
Banner and Mouser identify conveyor lines and robotic palletizing cells as example uses. In those applications, a machine-mounted block can place safety connections closer to e-stops, safety switches and light curtains, potentially reducing homerun cabling. The approach may also help integrators organize separate safety zones along extended material-handling equipment.

The enclosure is rated IP67, according to the manufacturer and distributor materials. That rating can be useful for field installation, but it should not be treated as a substitute for assessing connector selection, cable routing, washdown exposure, grounding, environmental conditions and the safety requirements of the completed machine. ([info.bannerengineering.com](https://info.bannerengineering.com/cs/groups/public/documents/literature/245780.pdf?utm_source=openai))
Controls integration and network confirmation
Banner specifies configuration through Rockwell Automation Studio 5000 using an included electronic data sheet file and selectable port presets for common devices. That makes RSio principally relevant to teams already standardizing on a compatible CIP Safety control architecture and Studio 5000 workflow. The product documentation identifies Studio 5000 as a qualified configuration tool and cautions that an appropriate qualified configuration tool is necessary to ensure the implemented configuration reflects the intended safety function. ([info.bannerengineering.com](https://info.bannerengineering.com/cs/groups/public/documents/literature/245780.pdf?utm_source=openai))
The ODVA Marketplace lists RSio under EtherNet/IP and CIP Safety and records an ODVA Declaration of Conformity, document number 12443, dated 2025. That supports network conformance status, but does not remove the installer’s responsibility to perform a documented risk assessment, design verification and validation for the complete machine. ([marketplace.odva.org](https://marketplace.odva.org/products/2918-rsio-remote-safe-i-o))
What purchasers should check before specifying
Procurement and engineering teams should confirm the model’s power-interface requirement early. RSio is offered with Mini power connectors rated for up to 10 A pass-through or M12 L-Code power connectors rated for up to 16 A pass-through; both versions use M12 A-Code I/O connections. Available downstream power, voltage-drop calculations, connector ecosystems and the intended field-device count can all affect that choice. ([au.mouser.com](https://au.mouser.com/en/newsroom/publicrelations-banner-rsio-remote-safe-io-2026final/))
Teams should also distinguish device capacity from a finished safety-system design. Although the platform supports substantial ISD device counts, the actual number and type of connected components must align with the safety controller, network design, response-time analysis, applicable standards and the machine’s documented risk assessment. The stated safety capability extends up to Category 4, Performance Level e and SIL 3 in Banner’s documentation, but the achieved level depends on the complete application rather than the I/O block alone.
