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.","metaTitle":"Schneider HMIG3U Harmony GTO HMI base unit, 256 MB RAM, Modbus","metaDescription":"Schneider HMIG3U Harmony GTO base unit: 256 MB RAM, 512 KB NVRAM, ARM Cortex-A9 600 MHz, Modbus/Modbus TCP/IP/Uni-Telway, 24 VDC, panel mount, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Depth":"1.8 in (45 mm)","Width":"7.4 in (188 mm)","Height":"5.2 in (131 mm)","Category":"US10MC222567","Standards":"CSA C22.2 No 142 ANSI/ISA 12-12-01 UL 508 Class I division 2 CSA C22.2 No 213 IEC 61132-2","Port Ethernet":"10BASE-T/100BASE-TX/1000BASE-T","Processor name":"ARM Cortex-A9","Type of cooling":"Natural convection","lifecycle_stage":"current","Pollution degree":"2 IEC 61131-2 ed.3","Range of Product":"Harmony GTU","Software package":"Vijeo Designer","Device short name":"Premium Box","Relative Humidity":"10...90 % non-condensing","Memory description":"256 MB RAM internal 2 x 13 mm board) 512 KB NVRAM backup memory","Operating altitude":"6561.68 ft (2000 m)","Vibration resistance":"3.5 mm constant amplitude 5...9 Hz) IEC 61131-2 9.8 m/s² 9...150 Hz) IEC 61131-2","Nbr. of units in pkg.":"1","Data storage equipment":"1 GB SD card","Product or Component Type":"Base unit","[Us] rated supply voltage":"12...24 V DC power supply","Integrated connection type":"Ethernet TCP/IP 2 RJ45 COM1 serial link RJ45 RS485 110...115200 bit/s COM1 serial link RJ45 RS485 187.5 kbit/s COM2 serial link SUB-D 9 RS232C/RS422/RS485 110...115200 bit/s COM2 serial link SUB-D 9 RS232C/RS422/RS485 187.5 kbit/s Auxiliary port terminal block Expansion unit fieldbus card USB 2.0 port 2 USB type A USB 2.0 port mini B USB","Communication port protocol":"Modbus Modbus TCP/IP Uni-Telway","Electromagnetic compatibility":"Electrostatic discharge immunity test level 3 conforming to IEC 61000-4-2","Ambient air temperature for storage":"-4...140 °F (-20...60 °C)","Ambient air temperature for operation":"32...140 °F (0...60 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$554.99","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a267066cb7a9c0d57730a15e05f5b493.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/HMIG3U/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/HMIG3U","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/HMIG3U when reusing this data.
