Roc431-S Smart IoT Meter: Precision Energy Monitoring with Unmatched Connectivity and Storage
In today’s rapidly evolving industrial and commercial landscape, energy efficiency is no longer just a cost-saving measure — it is a strategic imperative. From manufacturing plants and data centers to commercial buildings and renewable energy installations, the ability to monitor, analyze, and act upon real-time energy data has become essential for staying competitive. Yet many organizations still struggle with fragmented monitoring systems, limited data visibility, and complex integration challenges.
Enter the Roc431-S Smart IoT Meter — a compact, rail-mounted three-phase energy meter engineered to deliver precise measurements, robust connectivity, and enterprise-grade data management in a single, space-saving package.
Designed for Demanding Environments
The Roc431-S is purpose-built for modern energy monitoring applications. It supports a wide range of voltage configurations, including three-phase 230/400 V, single-phase 120/240 V, 277/480 V, and 230 V systems, making it suitable for diverse global installations. Whether you are monitoring secondary sides in medium- or high-voltage substations or directly wiring into low-voltage distribution panels, the Roc431-S adapts seamlessly with support for 3P4W, 3P3W, 1P3W, and 1P2W wiring systems.
Three Core Advantages That Set It Apart
1. Powerful Data Recording with Local Storage
One of the most distinguishing features of the Roc431-S is its built-in 32GB storage capacity. While many meters rely entirely on continuous cloud connectivity to retain historical data, the Roc431-S empowers users with onboard logging capabilities. It supports programmable interval recording and waveform capture, allowing engineers to analyze load profiles, detect power quality issues, and troubleshoot anomalies without the risk of data gaps. This is especially valuable in environments where network connectivity may be intermittent or where long-term historical analysis is required.
2. Extensive Connectivity and Expandability
The Roc431-S comes equipped with 4 digital inputs and 4 digital outputs as standard, enabling direct connection to alarms, pulse counters, and control devices. But its flexibility does not stop there. An expansion slot allows for customizable add-on modules — including zero-sequence current monitoring, temperature sensing, or additional input channels — ensuring the meter can grow with your application needs.
On the communication front, the meter is future-ready. It includes both RJ45 Ethernet and RS485 ports as standard, supporting Modbus-TCP and Modbus-RTU protocols. This dual-communication capability ensures seamless integration with SCADA systems, building management platforms, PLCs, and cloud-based energy management software, making it a versatile component for new installations or retrofit projects.
3. Flexible Power Supply Options
Installation environments vary widely, and the Roc431-S is designed to accommodate them. The meter is available in two power supply variants: 95–265 VAC for standard AC installations, and 5–36 VDC for low-voltage DC environments. For applications requiring even greater flexibility, an external expansion module can support 90–528 VAC for the main circuit, along with an auxiliary AC power supply — a feature particularly useful in industrial settings where voltage conditions may fluctuate.
Where the Roc431-S Excels
The versatility of the Roc431-S makes it suitable for a broad spectrum of applications:
Commercial Buildings: Perfect for tenant sub-metering, HVAC monitoring, and whole-building energy optimization.
Industrial Facilities: Provides machine-level energy tracking, load profiling, and power quality analysis to support efficiency initiatives.
Data Centers: Delivers high-accuracy metering with waveform capture to help optimize Power Usage Effectiveness (PUE).
Renewable Energy Systems: Ideal for monitoring inverter output, grid interface points, and compliance reporting.
Medium- and High-Voltage Substations: Serves as a reliable secondary-side metering solution with remote communication capabilities.
Quality You Can Rely On
Every Roc431-S meter is manufactured under strict quality controls and carries CE certification, ensuring compliance with international standards for safety and performance. The compact rail-mount design simplifies installation in crowded electrical panels, reducing both labor time and space requirements.
