4. Application Areas and Application Cases
Application Areas: The IS200ESELH2A is mainly used in power generation facilities, including thermal power plants, hydropower plants, and gas – fired power plants. It is also applicable in industrial settings where large – scale generators are used for self – power generation, such as in large manufacturing plants and data centers.
Application Case: In a thermal power plant, the IS200ESELH2A is installed in the generator’s excitation control system. When the power plant experiences a sudden increase in the electrical load, the module quickly detects the change in the generator’s output voltage. It then adjusts the excitation current to maintain the voltage at the desired level. This ensures that the power plant can continue to supply stable electricity to the grid, preventing power outages and voltage fluctuations.

With 8 isolated channels, the UUD148AE01 is tailored for systems that don’t require the 16-channel capacity of the UUD148AE02. This reduces unnecessary hardware investment in setups like small manufacturing cells or standalone machinery, where only a handful of discrete signals (e.g., door interlocks, sensor triggers) need monitoring. The module’s compact dimensions (half the width of the UUD148AE02) further enhance its suitability for space-constrained cabinets.
Balanced Performance:
While its response time (≤2ms) is slightly longer than the UUD148AE02’s (≤1ms), the UUD148AE01 still meets the needs of most industrial applications, including packaging lines and material handling systems. Its 2.5kVrms isolation matches that of the UUD148AE02, ensuring immunity to electrical noise from nearby motors or high-voltage equipment—critical for reliable signal acquisition in factory environments.
Energy and Cost Efficiency:
The UUD148AE01 consumes 2.8W of power, significantly less than the UUD148AE02’s 4.5W, making it a greener choice for low-power systems. Its lower channel count also translates to reduced wiring complexity and lower upfront costs, making it a cost-effective alternative when full 16-channel capacity isn’t required.
