Product details

Overview

The HMIG3UFC is a Schneider Harmony GTU HMI base unit running on a 24 V supply with a CPU RISC 600 MHz processor, 256 MB RAM internal and 512 KB NVRAM backup memory. It communicates over Modbus, Uni-Telway, and Modbus TCP/IP via dual RJ45 Ethernet ports, plus serial RS232C/RS422/RS485 and USB 2.0 connections. The unit is active in Schneider's current catalog; no end-of-life notice applies.

Memory sizing vs HMIG5U21

The HMIG3UFC carries 256 MB RAM internal and 512 KB NVRAM backup memory, while the HMIG5U21 offers 4 GB RAM internal and 512 KB NVRAM backup memory — a 16x RAM difference that matters for large-screen applications or heavy recipe storage.

Panel integration

Dimensions are 187.96 mm wide by 132.08 mm high by 45.72 mm deep; the unit cools by natural convection and fits a standard cut-out for the Harmony GTU range.
