G30 3-in-1 Smart IoT Gateway

Unify Your Network. Empower Your Energy Data.

KEYPLUS G30 3-in-1 Smart IoT Gateway (Ethernet / 4G / Wi-Fi)

The KEYPLUS G30 is a high-performance 3-in-1 Smart IoT Gateway engineered to aggregate, compute, and transmit critical telemetry across complex electrical and building infrastructures. Featuring integrated Ethernet, 4G LTE, and Wi-Fi uplinks alongside comprehensive MQTT, Modbus, SNMP 2.0, and IEC104 support, it connects up to 40 sub-devices on a standard DIN-rail footprint, ensuring 100% data integrity with edge offline caching.

Are Network Drops and Complex Wiring Holding Your System Back?

• Unstable Uplinks & Data Gaps: Transient network dropouts in harsh electrical environments frequently cause irreversible data loss and blind spots in energy audits.
• Bloated Multi-Protocol Architecture: Interfacing dozens of sub-meters, breakers, and sensors with conflicting communication protocols demands cumbersome wiring, expensive external converters, and high maintenance costs.

Multi-Protocol & 3-in-1 Flexible Connectivity

• Feature: Built-in Ethernet, 4G LTE (external antenna), and Wi-Fi uplinks, supporting standard industrial protocols including MQTT, Modbus-TCP, Modbus-RTU, SNMP 2.0, and IEC104.
• Advantage: Adapts immediately to any field network infrastructure without requiring additional third-party protocol translation hardware.
• Benefit: Minimizes deployment time, cuts integration expenditures, and establishes an exceptionally resilient communications backbone for your entire IoT estate.

Intelligent Offline Data Caching & Auto-Sync

• Feature: Embedded edge-computing storage engine that automatically preserves data records locally during unforeseen network disconnects.
• Advantage: Intelligently queues and pushes historical telemetry to the cloud platform the instant network communication is restored.
• Benefit: Guarantees uncompromised data fidelity and continuous auditing accuracy, completely safeguarding critical sub-billing and energy consumption records.

High-Density Sub-Device Consolidation

• Feature: Equipped with dual RS485 serial ports and dual Ethernet ports, managing up to 40 downstream sub-modules simultaneously.
• Advantage: Centralizes telemetry across dozens of energy meters, smart breakers, and environmental sensors into a single compact DIN-rail hub.
• Benefit: Maximizes panel real estate, streamlines control cabinet wiring, and drastically simplifies routine maintenance workflows.
