ABB RIO600 – Remote I/O for IEC 61850 Substation Automation and IED I/O Expansion
ABB RIO600 is a remote I/O unit designed to extend binary I/O close to the primary equipment and publish those signals over IEC 61850. From my experience, it’s a clean way to cut panel-to-panel copper, speed up bay interlocking, and keep feeder protection relays focused on protection instead of acting as wiring hubs. Utilities and industrial plants typically use RIO600 to collect status and command points from switchgear, transformer auxiliaries, and interlocks, then share them via GOOSE to Relion IEDs like REF615/620/630 or to a station controller.
One thing I appreciate is how fast commissioning can be when the engineering team already works with PCM600. You might notice that changes to I/O mapping and GOOSE subscriptions are much easier to maintain after a retrofit—especially when you’re phasing out hardwired intertrips. A maintenance supervisor at a transmission substation told us they trimmed roughly 60% of their copper runs on a bay upgrade by moving to RIO600-based distributed I/O.

Key Features
- IEC 61850 (Ed.2) with GOOSE – Publishes/receives status and commands over the process bus, reducing hardwiring between panels.
- Scalable binary I/O – Configurable combinations of binary inputs and outputs; fits small bay retrofits or larger switchboard expansions.
- Redundant Ethernet networking – Typically two 100 Mbps ports (RJ45 or fiber variant) to integrate with substation LAN designs.
- Time synchronization – Supports SNTP; many installations also use IRIG-B for tighter time stamping where available.
- Engineered in PCM600 – Familiar toolchain for Relion users; streamlines I/O mapping, GOOSE subscriptions, and maintenance.
- Distributed I/O concept – Place the unit near primary equipment to shorten copper runs and simplify cable trays.
- Event and diagnostics – Self-supervision and event records help pinpoint wiring issues or lost subscriptions in most cases.
- Flexible power variants – Typically available for 24–60 V DC or 110–240 V AC/DC station supplies (depending on order code).

Related or Supporting Products
- ABB REF615 / REF620 / REF630 – Feeder protection IEDs that subscribe to RIO600 GOOSE signals; choose if you also need full protection and control, not just I/O.
- ABB COM600E – Substation automation controller/gateway; aggregates IEC 61850 data from RIO600 and relays to the SCADA host.
- ABB REM615 / RET615 – Motor and transformer protection IEDs; pair with RIO600 where additional remote I/O is required at the process level.
- Alternative concept: central I/O in IED – If panel space is limited, selecting an IED variant with higher onboard I/O can reduce the need for a separate RIO600, though it might increase wiring length.
Installation & Maintenance
Installation environment
- Mount in a grounded metal cabinet with adequate ventilation; allow space around the unit for cable bend radius and service.
- Use shielded Cat5e/Cat6 or optical fiber according to substation LAN design; keep Ethernet away from high-current paths.
- Bond shields and the RIO600 earthing point at a single reference (typical star earthing practice) to minimize induced noise.
- For I/O wiring, follow station battery voltage and wet/dry contact module requirements; verify polarity on binary inputs.
Commissioning tips
- Engineer the device with PCM600; align GOOSE publisher/subscriber datasets and verify with a network analyzer or IED event lists.
- Set SNTP (or IRIG-B if used) before final time-stamp verification; many mis-operations track back to unsynchronized time.
- Label I/O terminals clearly; perform point-to-point loop checks with the bay IEDs prior to energization.
Routine maintenance
- Visual inspection every 6–12 months; clean dust from vents and check terminal tightness.
- Revalidate GOOSE subscriptions after any network topology change; keep a baseline export in PCM600 for comparison.
- Firmware updates via PCM600 as recommended by ABB; schedule during outages and document release notes for compliance.
Quality & Certifications
- CE-marked; RoHS compliant (typical for Relion family)
- IEC 61850 Ed.2 interoperability; commonly UCAIug conformance tested
- Manufacturer quality system aligned with ISO standards
- Warranty: 12 months from shipment (365 days)
If you’re planning a bay retrofit or a new IEC 61850 build, RIO600 seems to be a practical way to keep wiring simple while staying fully compatible with Relion IEDs. Share your target I/O count and network preferences (RJ45 or fiber), and we’ll match the correct power variant and accessory set.
