II. Core Functional Characteristics

1. Four-channel standard servo drives, balanced and stable output

Equipped with 4 completely independent standard servo drive channels, each channel has an adjustable output current of 0.8–4A, suitable for standard power electro-hydraulic servo valves, ordinary DC servo motors, small and medium-sized linear actuators and pneumatic servo positioners, covering the mainstream conventional servo loads in industrial sites.

Output types support PWM (1–20kHz adjustable) or ±10V analog quantity, considering resistive and inductive loads, with built-in overcurrent, short circuit, overheat, reverse connection protection, single-channel fault isolation, not affecting the operation of other channels, ensuring stable operation of multi-executor clusters.

Integrated 32-bit hardware PID controller, single-channel control cycle ≤1.2ms, supports position/velocity dual closed-loop, positioning accuracy ±0.1% FS, resolution 16 bits, moderate response speed, suitable for conventional load fluctuations and multi-valve group synchronous adjustment scenarios.

2. Standard feedback compatibility, reliable and stable closed-loop control

Directly connects to LVDT/RVDT (17V AC/1kHz), potentiometers, etc., mainstream position feedback devices, 4-channel independent feedback acquisition, real-time synchronous monitoring of each actuator position, forming full closed-loop control, effectively suppressing valve drift and lag, suitable for conventional positioning scenarios with accuracy requirements.

Built-in analog + digital dual low-pass filter circuit, suppressing industrial site high-frequency interference, stable and without jitter, feedback acquisition response time ≤8ms, meeting the closed-loop requirements of conventional dynamic actuators, suitable for multi-feedback signal parallel acquisition.

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

Integrated 2 channels of analog quantity input (AI), supporting 4–20mA, 0–10V, 1–5V standard signals, 16-bit resolution, accuracy ±0.1% FS, electrical isolation between channels, used for synchronous monitoring of servo system pressure, temperature, flow and other auxiliary parameters, achieving integration of control and monitoring, suitable for conventional process parameter acquisition requirements.

4. High-speed communication and redundant configuration, ensuring continuous operation

Backplane communication uses Ovation dedicated bus, data refresh rate 1.2ms, real-time synchronizes controller instructions and module feedback data, ensuring multi-channel instructions synchronization, suitable for conventional load fluctuation scenarios.

RS-485 serial port is configured, supports Modbus RTU protocol, baud rate 9600–57600bps configurable, can be connected to the upper computer or handheld terminal, enabling remote parameter configuration, fault diagnosis and data acquisition, facilitating debugging and maintenance. 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), without affecting system operation.

Compatible with redundant pairing. The dual-module redundant switching time is ≤ 5ms, with no disturbance control. It is suitable for conventional critical multi-loop control scenarios, enhancing system operational reliability.

5. Industrial-grade rugged design, stable operation in regular environments

Operating temperature range: -20℃ ~ +60℃, storage temperature: -40℃ ~ +85℃, relative humidity: 5%–95% RH (no condensation), suitable for conventional industrial workshops, cabinet rooms, meeting the temperature requirements of most indoor industrial scenarios.

Vibration resistance 5g (IEC 60068-2-6), shock resistance 30g, triple electrical isolation (channel - system - power supply), isolation withstand voltage 1500V DC, ESD protection ±20kV, surge protection ±4kV, effectively resisting common industrial site electromagnetic interference and ground loop current, suitable for general complex industrial environments.

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

Has four-level full-link diagnosis capabilities, covering core links such as module power supply, backplane communication, drive output, feedback signal, and basic state of actuators (stiction, overload, breakage) of the system. It monitors abnormalities in real time and accurately locates faulty channels and components.

The panel is equipped with high-brightness LED indicators (power, communication, fault, channel 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 warnings, allowing for early隐患排查 and reducing unplanned downtime risks.
