Introduction to the STBNCO2212 Network Interface Module
When a distributed I/O island needs a reliable CANopen head, the STBNCO2212 from Schneider Electric delivers. This Standard Network Interface Module (NIM) belongs to the Advantys STB series and connects field I/O to a CANopen network through a single, compact interface. It measures just 128.3 × 70 × 40 mm and weighs 0.145 kg, so it fits neatly into tight control cabinets. The module runs on a 24V DC supply and can address up to 32 I/O modules per island.
Because Schneider Electric has discontinued this model and superseded it with the Modicon X80 range, buyers should treat it as a legacy part. SpareTechPLC helps you confirm current lifecycle status and availability before you commit to a purchase.

What the Key Specifications Mean in Practice
CANopen Communication via a 9-Pin SUB-D Port
The built-in 9-pin SUB-D (DB-9S) connector follows the DIN 41652 standard. That means standard CANopen cabling mates directly, with no adapters. The module speaks CANopen natively, so it slots into existing CANopen networks without protocol conversion.
24V DC Supply and 32-Module Capacity
The 24V DC supply matches the control voltage common in industrial panels. One NIM can address up to 32 I/O modules per island, which keeps the network architecture simple as the machine grows.
IP20 Protection and Compact Footprint
IP20 protection suits clean, enclosed environments such as control rooms and cabinets. The slim 128.3 × 70 × 40 mm housing saves DIN-rail space, and the low 0.145 kg weight eases handling during service work.
Where the Advantys STB NIM Fits
Legacy CANopen I/O Islands
Plants that standardized on Advantys STB islands still rely on this NIM to keep production lines running. When a unit fails, a like-for-like replacement avoids rewiring the whole island.
Machine Retrofits and Upgrades
Integrators upgrading older equipment often keep the existing CANopen backbone. The STBNCO2212 lets them add or replace the network head without touching field wiring or I/O modules.
Spare Parts Stocking
Because the model is discontinued, maintenance teams benefit from holding a verified spare. A single spare NIM can prevent long downtime while a replacement strategy is planned.
Installation and Setup Guidance
Mount the module on a DIN rail inside a suitable enclosure. Confirm the 24V DC supply polarity and voltage before energizing the island. Connect the CANopen cable to the 9-pin SUB-D port and verify the network termination and addressing per your system documentation. Keep the module within an IP20 environment; avoid dust, moisture, and conductive contamination. Follow Schneider Electric’s installation manual for exact procedures.
Maintenance and Reliability
Inspect the module periodically for loose connectors, discoloration, and secure DIN-rail mounting. The 9-pin SUB-D port is the main wear point, so check mating contacts during scheduled service. Keep cabinet temperature stable and free of condensation. Since the product is discontinued, plan a long-term replacement path toward the Modicon X80 range and confirm spare availability with SpareTechPLC.
Compatibility and Integration Notes
The STBNCO2212 works within Advantys STB islands and communicates over CANopen. It supports up to 32 addressable I/O modules per island. Before purchase, verify that your existing island, cabling, and controller match these requirements. If your architecture has moved to Modicon X80, discuss migration options with SpareTechPLC.
Selection Checklist Before You Buy
- Confirm your network uses CANopen.
- Verify the island accepts a 9-pin SUB-D (DB-9S) connection.
- Check that your I/O count stays within 32 modules per island.
- Confirm a 24V DC supply is available.
- Ask SpareTechPLC to verify lifecycle status and stock.
