4. Application Areas and Application Cases
Application Areas: The IS200ERBPG1A 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, refineries, and data centers.
Application Case: In a hydropower plant, the IS200ERBPG1A is installed in the generator’s excitation system. When the water flow through the turbines changes due to seasonal variations or reservoir management, the generator’s load and output requirements change. The IS200ERBPG1A quickly detects these changes through the input signals and adjusts the excitation current accordingly. This ensures that the generator’s output voltage remains stable, and the power generated is of high quality, suitable for transmission to the grid.

Ultra-Low Cost for Budget-Critical Applications: The Motorola MVME162-12’s simplified design (fixed ranges, 10-bit resolution, single-ended inputs) reduces hardware costs by 40% compared to Motorola MVME162-412. For a small organic farm’s irrigation monitoring system, pairing Motorola MVME-201 (8 built-in digital I/O) with Motorola MVME162-12 provides 4 analog inputs (for soil moisture sensors) and 2 analog outputs (for valve positioning)—all at a price point 35% lower than mid-tier analog modules. This affordability lets small operations automate basic analog tasks without overinvesting in unused precision.
Zero Configuration for Fast Deployment: Unlike Motorola MVME162-412 (software-configurable ranges), the Motorola MVME162-12 uses fixed 0–5 VDC input/output ranges—requiring no software setup or calibration tools. For a workshop’s tool cooling system, technicians can wire 4 temperature sensors (0–5 VDC) to the inputs and 2 fan controllers (0–5 VDC) to the outputs, then start using the module immediately via basic VME register reads/writes. This simplicity cuts deployment time by 80% compared to configurable modules, critical for small teams with limited automation expertise.
Compact Design for Chassis Space Efficiency: The Motorola MVME162-12 retains the standard 3U VME form factor of higher-end MVME162 modules but uses a streamlined circuit design to minimize power draw (0.5 A typical vs. 0.8 A for MVME162-412). In a portable test enclosure (e.g., a mobile environmental sensor unit), this low power consumption extends battery life during fieldwork, while the 3U size fits alongside a Motorola MVME-167-01A and a Motorola MVME-050 (digital I/O) in a compact chassis. This space efficiency eliminates the need for larger, costlier enclosures—saving an additional 20% on system hardware.
