Material Composition: Military-grade wide-temperature components, thickened conformal coating (moisture-proof, salt-spray-proof, dust-proof, oil-proof).
Structural Features: The main board surface has eight plug connectors primarily along the board edges, plus five jack connectors. The board includes several voltage regulators and a line MOVs (Metal Oxide Varistor). The integrated IS210BPPB sub-board is secured to the main board via four screws through factory-drilled holes and standoffs. The sub-board features two jack connectors on one edge, a 3-position female plug connector, and a multi-pin female plug connector. It contains ICs, inductors, resistors, and capacitors, with two LED indicators.
Working Principle: The module receives 24V DC from the rack backplane and generates multiple isolated analog power rails and high-precision reference voltages. The IS210BPPB sub-board forms a secondary protection network with additional inductors, capacitors, MOVs, and LED status indicators, significantly enhancing suppression of transient overvoltages from lightning strikes and grid fluctuations.
Functional Features: Compared to IS215AEPCH1B, the C-revision improves output accuracy to ±0.03% FS, reduces ripple noise below 8 mV, and enhances electrical isolation to 3.0 kV. The ultra-clean power supply effectively suppresses ground loops and EMI, ensuring zero drift in signal acquisition even in high-vibration, high-interference wind farm environments.
Application Scenarios: Wind turbine pitch control systems, excitation systems, and Mark VI renewable energy and power generation control loops requiring ultra-clean isolated power for position, speed, and acceleration sensors.
Installation Requirements: Install in Mark VI rack backplane with 24 V DC supply. The IS210BPPB sub-board must be properly secured with all four screws.
Usage Precautions: The C-revision is not directly interchangeable with B-revision without verifying system compatibility. The enhanced conformal coating allows operation in extreme temperatures from -30°C to +70°C.
