Selection Guide
Use the following criteria to select the correct CPU module for your UR Series relay:
- Step 1 — Identify your relay model: Check the relay nameplate (e.g., G60, L90, T60)
- Step 2 — Confirm chassis slot count: 6-slot or 9-slot chassis determines compatible CPU variants
- Step 3 — Check firmware version: CPU modules must match or exceed the relay’s minimum firmware requirement
- Step 4 — Verify communication ports: Confirm required protocols (IEC 61850, DNP3, Modbus) are supported by the selected CPU
- Step 5 — Contact Konmask: Send your relay model and existing CPU part number — we will confirm compatibility before shipment
