Product Overview

The Schneider Electric 416NHM30032A is a dual-port Modbus Plus (MB+) PCI communication adapter card designed to seamlessly integrate industrial computers into Schneider Electric’s Modicon automation ecosystems. As part of the ConneXium series, this adapter serves as a specialized “network interface card” for Modbus Plus networks, enabling high-performance data exchange between PC-based engineering workstations and Modicon Quantum, Premium, and M340 series PLCs . The Schneider Electric 416NHM30032A bridges the IT and OT worlds by allowing supervisory control and data acquisition (SCADA) software, programming platforms like Concept and Unity Pro, and HMI applications to directly access real-time process data from Modbus Plus devices .

At its core, the Schneider Electric 416NHM30032A features a dedicated ASIC chip specifically engineered to handle the Modbus Plus token-passing protocol at a fixed transmission rate of 1 Mbps . The card’s dual RJ-45 ports provide remarkable network flexibility, enabling a single workstation to connect two physically isolated MB+ segments or to participate in complex network topologies with configurable terminal resistors . Supporting both 5V and 3.3V PCI bus voltages, the Schneider Electric 416NHM30032A offers broad compatibility with legacy industrial computers . Its robust industrial-grade construction ensures reliable operation in demanding environments, with electrical isolation of 500V RMS between the ports and the PCI bus protecting the host system from field-side electrical disturbances .
