Product Introduction
When integrating multiple serial devices into a control system, the Schneider FBM230 provides a unified Modbus master interface. Part of the Foxboro control system family, the FBM230 acts as a Modbus Master driver for both serial and TCP/IP networks. It can connect to up to 64 RS-485 devices or up to 4 direct connect RS-232/RS-422 devices, making it a versatile solution for industrial automation.

Industry Applications
The Schneider FBM230 excels in scenarios requiring flexible serial communication. Typical uses include connecting remote RTUs, PLCs, and flow computers to a centralized control system. In water treatment plants, it integrates multiple Modbus devices over long distances using RS-485 multidrop. In oil and gas facilities, the FBM230 allows a single module to handle both serial and Ethernet-based Modbus devices, reducing hardware complexity.
Installation & Setup
Mount the FBM230 in a suitable enclosure using its mounting lugs (114 mm height including lugs). Connect the termination assembly (TA) according to EIA RS-232, RS-422, or RS-485 standards. For RS-485, use twisted-pair shielded cable. Configure each port individually via software for the desired interface and protocol (Modbus RTU, ASCII, or TCP). The module supports big endian or little endian data formats, selectable via configuration tools.
Selection Guide & Purchasing Advice
Before purchasing the Schneider FBM230, verify your system's compatibility with the required protocols and voltage supply. Ensure the TA is included or ordered separately if needed. For seamless integration, confirm that your host controller supports Foxboro I/O drivers. ubest101 offers this module along with genuine replacement parts and accessories.
