The Applications of the EM220-RTU-4DI2DO-GW Energy Meter
1. Energy Transparency in Industrial Production Lines
In automated production environments, multiple machines often share the same electrical infrastructure, making energy inefficiencies difficult to detect. The EM220-RTU-4DI2DO-GW is installed at machine feeders to measure voltage, current, and power per production segment using external current transformers. Energy data is updated every second and transmitted to control systems, allowing engineers to compare consumption during idle and active states. Digital inputs capture machine status signals, enabling energy usage to be directly linked to production activity. This insight supports targeted optimization, reduces unnecessary standby consumption, and improves overall equipment energy efficiency.
2. Electrical Load Management in Commercial Buildings
Commercial facilities frequently experience uneven electrical loading across floors or zones, leading to higher operating costs and reduced power quality. By deploying the EM220-RTU-4DI2DO-GW in distribution panels, facility teams gain accurate visibility into single-phase and three-phase consumption. Local display access simplifies commissioning and maintenance checks, while networked data supports centralized monitoring. Measurement of power factor and reactive energy highlights inefficient loads such as aging HVAC systems. Configurable digital outputs can be used to signal abnormal conditions, helping maintenance teams respond early and maintain stable, energy-efficient building operation.
3. Monitoring Power Flow in Renewable Energy Systems
Renewable energy installations require precise tracking of both generated and consumed power to maintain system stability. The EM220-RTU-4DI2DO-GW is used in solar or hybrid systems to monitor bidirectional energy flow between inverters, storage, and the grid. Four-quadrant measurement ensures accurate recording of import and export energy values. High sampling performance enables fast feedback for energy controllers, supporting effective load balancing and storage management. This detailed visibility helps operators verify system performance, improve self-consumption rates, and maintain reliable operation under changing generation conditions.
4. Accurate Energy Allocation in Multi-Tenant Facilities
In shared facilities, allocating energy costs fairly between tenants is a persistent challenge. Installing the EM220-RTU-4DI2DO-GW at individual tenant feeders allows precise, independent measurement of consumption. High accuracy ensures confidence in billing data, while automated data collection removes the need for manual meter readings. Digital inputs can record operating periods or equipment usage patterns, adding context to consumption figures. This approach increases transparency, reduces billing disputes, and enables facility operators to implement fair, data-driven energy cost allocation strategies.
