Product details

Overview

The HMIG3U is a Harmony GTO base unit from Schneider, running an ARM Cortex-A9 processor at 600 MHz with 256 MB RAM and 512 KB NVRAM backup memory. It communicates over Modbus, Modbus TCP/IP, and Uni-Telway, with a 10BASE-T/100BASE-TX/1000BASE-T Ethernet port, and is powered by 24 VDC.

Memory and storage comparison

The HMIG3U carries 256 MB RAM and 512 KB NVRAM; by contrast, the HMIZSD4G is a 4 GB SD memory card accessory, not a base unit — choose the HMIG3U when the BOM requires the full base unit with onboard memory, and add the HMIZSD4G only if additional removable storage is needed.

Compliance and certifications

The HMIG3U carries CE, CULus, ATEX, IEC-Ex, RCM, GL, KC, CUL, EAC, ABS, BV, CCS, DNV, LR, RINA, UKCA, and UKEX certifications, and complies with CSA C22.2 No 142, ANSI/ISA 12-12-01, UL 508 Class I Division 2, CSA C22.2 No 213, and IEC 61132-2 standards. It is an active catalog item; lead time is confirmed via RFQ.
