Schneider STBNIC2212 Advantys STB Network Module

Schneider STBNIC2212 Advantys STB Network Interface Module

Product Introduction

The STBNIC2212 acts as the communication gateway for Schneider Electric Advantys STB distributed I/O islands. Specifically, this standard network interface module connects field I/O to an EtherNet/IP network. It presents the entire island as one node, which simplifies data exchange with controllers and supervisory systems.

This single-port design focuses on reliable industrial Ethernet communication. For instance, it suits applications where a compact, cost-effective NIM is preferred over a dual-port variant. Furthermore, the module pairs an RJ45 port with an RS232 service port for local setup and diagnostics.

Communication and Protocol Support

The STBNIC2212 module delivers solid communication performance. It features one RJ45 port plus an RS232 port using an HE-13, 8-way female connector. Additionally, it supports 10/100 Mbit/s transmission rates over standard IEEE 802.3 networks.

The module communicates using the EtherNet/IP protocol. Therefore, it integrates smoothly with Allen-Bradley and other EtherNet/IP-based control platforms. Besides network messaging, the RS232 port assists with local configuration tasks. Meanwhile, this network interface module can address up to 32 I/O modules within a single island.

Electrical Specifications and Power

Power requirements for the STBNIC2212 are simple and consistent. It operates on a 24V DC supply voltage with SELV isolation. Moreover, the module provides a logic bus output of 5.25V DC.

The logic bus output current reaches 1.2 A nominal. This capacity supports the attached I/O modules across the island. However, installers should confirm total island load before commissioning. In addition, correct grounding and stable 24V DC supply improve long-term reliability.

Mechanical and Environmental Parameters

The STBNIC2212 uses a compact housing for tight control cabinets. Its dimensions measure 128.3 mm in height, 70 mm in width, and 40 mm in depth. The module weighs approximately 0.145 kg. It mounts quickly on a standard 35 mm DIN rail.

Environmental specifications support general industrial use. The protection rating is IP20, which suits clean and controlled environments. Operating and storage temperature data are not published for this module. Therefore, keep the installation within the cabinet conditions recommended for the Advantys STB island.

Installation Guide

Installing the STBNIC2212 follows a clear sequence. First, mount the module onto a 35 mm DIN rail inside the Advantys STB island assembly. Next, connect the 24V DC SELV power supply to the correct terminals. Then, attach the Ethernet cable to the RJ45 port for network access.

Local setup uses the RS232 service port. Specifically, connect a compatible cable to the HE-13, 8-way female connector. After that, assign network parameters and configure the I/O modules in the island. Finally, check all status indicators to confirm normal operation before starting the line.
