RMIO-02C 64379160 ABB Programmable I/O expansion module Relion® 615/620 series protection relay
Product Overview
ABB RMIO-02C is a programmable I/O expansion module specifically designed for the Relion® 615 and 620 series multi-functional protection relays (such as REF615, REM615, RET615, REU615, etc.). By connecting to the local I/O bus of the main relay, RMIO-02C can significantly expand the digital input (DI) and digital output (DO) capabilities of the device, meeting the advanced application requirements such as complex interlocking, status feedback, and remote control.
Core features
Flexible I/O configuration
8-channel programmable digital input (DI) : Supports dry contacts or wet contacts (24-250 V DC/AC)
4-channel programmable relay output (DO) : single-pole double-throw (SPDT) contacts, 5 A @ 250 V AC
Plug-and-play expansion: Connected to the back I/O interface of the main relay via a dedicated flat cable, automatically recognized
No external power supply required: Powered by the main relay through the bus (power consumption ≤ 2W)
LED status indication: Each DI/DO channel is equipped with a green LED to display the status in real time
High anti-interference design: Complies with IEC 61000-4 series EMC standards and is suitable for harsh industrial environments
Support for logic programming: All I/O can be freely mapped to protection functions, alarms, remote control commands, etc. in PCM600 or Relion engineering tools
Technical parameters
Motor protection system: Extended start/stop signals, cooling fan control, fault reset and other auxiliary circuits
Substation automation: Collect the positions of disconnectors and the status of grounding switches, and control the opening and closing of circuit breakers
Industrial distribution panels: Achieve multi-level interlocking (such as "Prohibit simultaneous closing") and backup power switching logic
Pump station/fan group control: Centralized monitoring of the operating status of multiple devices, remote start and stop
Renovation project: Rapidly increase the number of I/O points to meet new demands without replacing the main relay
Installation and Usage instructions
Mechanical installation
Install RMIO-02C on the DIN rail on the right side of the main relay (it is recommended that the spacing be ≤ 10 cm).
Use the included fixed clips to prevent loosening.
Electrical connection
Connect the I/O EXT interface on the back of the main relay to the IN interface of RMIO-02C with a dedicated flat cable;
The on-site signal line is connected to the module terminals (DI: terminals 1-16; DO: terminals 17-28).
Software configuration
Open the main relay project in the PCM600 engineering tool;
Automatically identify RMIO-02C and allocate DI/DO functions (such as "Remote Signaling 1", "Trip Exit 2");
Support custom logical equations (such as DI1 AND DI2 → DO1).
Debugging and verification
Observe the input trigger and output action through the LED.
Confirm that the signal upload is correct in the HMI or background system.
