Description

• • Interface and Communication Parameters
    • Transducer Interface: It is equipped with two configurable position transducer interfaces that can be used as SSI (master or slave) or incremental encoders.
    • I/O Interfaces: It has 8 analog input ports and 2 analog output ports, all with 16-bit resolution and configurable ranges, as well as 8 digital I/O ports.
    • Bus Interfaces: It includes two CAN/CANopen interfaces, two TIA/EIA 232 interfaces, an Ethernet interface and an e-bus interface for expansion modules, and also supports Profibus-DP slave as an optional interface.
• Function Features
  • Ultra-high Precision Drive Control: It adopts MOOG’s proprietary linear amplification circuit and closed-loop feedback control algorithm, which can accurately drive single-coil and dual-coil servo valves. The control accuracy of the servo valve spool displacement reaches ±0.001mm, which fully meets the high-precision control requirements of scenarios such as aerospace component testing.
  • Strong Anti-interference Capability: The module adopts a double-layer shielding structure inside. The input and output signal terminals are integrated with common-mode inductors and transient voltage suppressor diodes. It can effectively resist electromagnetic interference and surge impact in complex industrial environments such as machine tools and metallurgical plants, ensuring stable operation of the module.
  • Comprehensive Fault Protection and Diagnosis: The power supply circuit is integrated with over-voltage, over-current and over-temperature protection functions. When an abnormal situation occurs, it will automatically cut off the output and trigger an alarm. It can identify 8 common faults such as signal loss and coil open circuit, and display fault information through LED indicators while outputting fault codes through communication ports.
  • Flexible Expansion and Compatibility: It supports function expansion through the internal expansion bus. Additional high-resolution analog and digital I/O modules and communication modules can be installed. The rich interface design enables it to be seamlessly connected with various upper controllers, servo valves and position sensors in the market.
  • Convenient Operation and Maintenance: It can collect key parameters such as servo valve coil temperature, drive current and input signal amplitude in real time. It can upload data to upper computers such as PLCs and HMIs through the RS485 communication interface supporting the Modbus RTU protocol, allowing operators to remotely monitor the module operation status.
• Application Scenarios
  • Aerospace Test Benches: It is widely used in aircraft rudder surface loading test benches, engine component performance test platforms and other aerospace-related test equipment. It accurately controls the servo valve to realize the precise loading and motion simulation of test components, providing reliable data support for the performance verification of aerospace components.
