2. Dual feedback redundancy acquisition, 3kHz LVT high-speed feedback

Unique dual feedback redundancy design in the industry, simultaneously connects 3kHz LVT (linear variable transformer, 19Vpp) + LVDT/RVDT/encoder, synchronously collects position signals, double verification eliminates feedback errors, significantly improves control reliability in extreme conditions.

LVT output frequency 3kHz (highest in the series), feedback processing response time ≤5ms, suitable for position closed-loop of high-speed motion mechanisms, effectively suppresses high-frequency interference, signal stability is extremely strong, eliminates valve drift and lag problems.

3. High-precision analog quantity acquisition, precise monitoring of process parameters

Integrated 2-channel analog quantity input (AI), supports 4–20mA, 0–10V, 1–5V standard signals, 16-bit resolution, accuracy ±0.1% FS, electrical isolation between channels, used for synchronous monitoring of key auxiliary parameters such as pressure, temperature, and flow in the heavy-duty servo system, achieving control and monitoring integration.

4. High-speed communication and redundant adaptation, continuous operation in extreme conditions

Backplane communication uses Ovation dedicated bus, data refresh rate 0.8ms, synchronizes controller instructions and module feedback data, ensures synchronization of dual-channel instructions, suitable for high-dynamic load fluctuation scenarios.

Configured RS-485 serial port, supports Modbus RTU protocol, baud rate 9600–57600bps configurable, can be connected to the upper computer or handheld terminal, realizes remote parameter configuration, fault diagnosis, and data collection, convenient debugging and maintenance in extreme environments. Supports online hot swapping, allowing module replacement without downtime. After insertion, it automatically identifies and synchronizes parameters, and the output status can be customized (keep, reset, preset). It does not affect system operation.

Compatible with redundant pairing. The dual-module redundant switching time is ≤ 3ms, with no disturbance control. It is suitable for critical heavy-load control scenarios and further enhances system reliability.

6. Seven-level full-link diagnosis, precise fault location and warning

Has seven-level full-link diagnosis capabilities, covering module power supply, backplane communication, drive output, dual feedback signals, actuator status (stuck, overload, broken wire, abnormal feedback), temperature, voltage and other full links. It monitors abnormalities in real time and accurately locates the faulty channel and component.

The panel is equipped with high-brightness LED indicators (power, communication, fault, channel status, feedback status), making the operating status visible; fault codes and detailed descriptions are uploaded to the Ovation system in real time, supporting remote diagnosis, trend recording and fault warning, allowing for early隐患排查 and reducing unplanned downtime risks in extreme conditions.
