III. Key Features

3.1 Isolated Preprocessing of Multi-Type Field Signals

Filter, limit and isolate on-site analog and discrete signals to eliminate industrial electromagnetic interference, ensure stable and accurate data transmission between field equipment and main control system, and avoid safety interlock misoperation caused by signal distortion.

3.2 High-Density Centralized I/O Collection & Safety Load Drive

Integrated multi-channel signal acquisition and relay output functions realize all-round operating condition monitoring and key safety protection loop drive for wind turbines, meeting the intensive control demand of new energy equipment with massive field measuring and control points.

3.3 Full-Channel Self-Diagnosis & Local Visual Fault Alarm

Real-time monitoring of each channel’s operating state, fault latch via local LED and remote fault information uploading, rapidly locating abnormal field cables and equipment to greatly improve on-site maintenance efficiency.

3.4 Millisecond SOE Event Sequential Recording for Fault Traceability

Accurately capture transient equipment status change and protection action events with unified high-precision timestamps, providing reliable data support for unit accident analysis and industrial safety compliance auditing.

3.5 TMR Triple Redundant Safety Deployment

Supports three-board 2oo3 hardware voting architecture to filter abnormal single-point signal data, meet SIL2 functional safety standards, and ensure the reliability of wind turbine safety protection functions under single hardware failure conditions.

IV. Working Principle

After power-on self-test and bus communication handshake, the board enters periodic signal acquisition operation. Field analog signals are conditioned, filtered and isolated and uploaded to the I/O Pack controller via the IONet backplane bus; discrete contact signals are de-bounced and opto-isolated for status sampling and SOE timestamp recording. The main control interlock instruction drives the on-board relay to actuate field safety execution devices. Each channel is equipped with real-time fault monitoring circuit to cut off abnormal loop output and latch alarm information once overload or short circuit occurs. The conformal coating continuously protects the PCB circuit from harsh environmental erosion to guarantee long-term stable signal transmission.
