Product Overview

The MG3-1G-1G-PM is an integrated industrial power management and dual Gigabit Ethernet I/O module manufactured by Magnetek, designed to combine regulated power conversion, isolated field signal acquisition and network data routing within a single compact DIN rail housing. This all-in-one unit integrates multi-channel analog and discrete I/O acquisition circuits with a built-in two-port unmanaged Gigabit industrial switch, functioning as a decentralized edge gateway for material handling systems, crane control, elevator automation and heavy-duty factory machinery control frameworks.

It addresses multiple practical limitations of separated discrete components in machine control cabinets, including excessive space occupation from standalone power supplies, separate Ethernet switches and remote I/O blocks, unstable power output caused by fluctuating 24VDC bus voltage, unisolated field signals inducing communication interference, and complicated wiring layouts that elevate troubleshooting difficulty during equipment breakdowns. Internal 1.5kV magnetic isolation on Ethernet ports and optocoupler isolation on all I/O loops effectively block ground loop currents and electromagnetic noise generated by inverters, contactors and large drive motors, maintaining stable real-time data transmission between local sensors and upper-level PLC or SCADA hosts.
