Product details

Overview

The HMIG3X is a Harmony GTUX eXtreme Box base unit running an ARM Cortex-A9 processor with 256 MB RAM and 512 KB NVRAM backup memory, powered by a 12 VDC supply. It integrates Modbus TCP/IP, Modbus serial, and Uni-Telway protocols over two RJ45 Ethernet ports and two serial links. Rated for 392 m/s² shock in X, Y, Z directions per IEC 61131-2, it is built for vibration-prone environments. Certifications include CE, KC, RCM, EAC, ATEX zone 2/22, IEC-Ex, UL, CSA, UKCA, and UKEX.

Comparison vs HMIG5UL8B

Compared to the HMIG5UL8B, the HMIG3X runs on 12 VDC (vs 24 VDC) and carries 256 MB RAM (vs 2 GB RAM). The HMIG5UL8B adds a 10BASE-T/100BASE-TX/1000BASE-T Ethernet port; the HMIG3X has two RJ45 ports at 10/100/1000 but no dedicated Gigabit port. Both share Modbus TCP/IP and Uni-Telway protocol support.

The HMIG3X is an active Schneider catalog item; lead time is confirmed via RFQ. No end-of-life notice is posted.
