Description
ABB RIO600 Modular DIN‑Rail Remote I/O Unit for Relion IED & IEC 61850 Substation Automation
Product Introduction
The ABB RIO600 is a stackable modular remote I/O platform developed for medium‑voltage substation automation and grid distribution applications. It serves as distributed signal expansion hardware for ABB Relion® protection & control IEDs and COM600 substation gateway. Built on a flexible DIN‑rail stacking architecture, the system combines power supply, communication module and mixed I/O slices to collect field binary status, analog measurement and temperature signals, then transmits real‑time data via high‑speed Ethernet. Native support for IEC 61850 GOOSE and Modbus‑TCP enables fast peer‑to‑peer interlocking between switchgear, protection relays and upper SCADA. It can implement Fault Passage Indication (FPI) for distribution network fault localization, greatly reducing heavy hardwiring inside switchgear cubicles. Widely deployed in primary & secondary substations, RIO600 is commonly stocked as spare assembly and upgrade component for digital substation retrofit projects.

Specific Application Information
- Protection relay I/O expansion: Increase binary input & output channels for Relion series IEDs (REC615, REF615 etc.) inside MV switchgear.
- Switchgear status acquisition: Collect circuit breaker, disconnector and earthing switch position feedback signals.
- Remote interlock execution: Receive GOOSE trip/blocking commands from protection relays to drive switchgear auxiliary circuits.
- Distribution fault detection: Directional Fault Passage Indication (FPI) for overhead lines and cable feeders to locate short‑circuit & earth faults.
- Power parameter monitoring: Measure current, voltage, active/reactive power and power quality with lightweight MV sensors.
- Temperature monitoring: RTD Pt100 measurement for cable joints, busbars and transformer auxiliary temperature points.
- Station data forwarding: Upload field signals to COM600, RTU and central SCADA system via Modbus TCP protocol.
- Motorized switch control: Smart control of two‑position / three‑position disconnectors and earthing switches.
