Features and Functions

Modular redundancy structure: It has three identical sub circuits, each of which performs independent control to ensure high reliability and stability of the system. In addition, it also has a dedicated hardware/software architecture for “voting” on inputs and outputs, which can withstand harsh industrial environments.

Intelligent functions: The intelligent functions in the input and output modules can reduce the workload of the main processor. For example, the microprocessor of the input module will filter and repair the input and diagnose hardware faults on the module, while the microprocessor of the output module provides information for the voting of output data, checks the validity of the output status through the feedback loop voltage at the output terminal, and can diagnose field line problems.

On site installation and maintenance: Supports online module level installation and maintenance, does not interfere with on-site wiring, and daily maintenance can be carried out during system startup and operation without interrupting the control process.

High scalability: Supports multiple I/O modules and communication modules, can connect to various external devices such as Modbus hosts, Foxboro, and Honeywell distributed control systems (DCS), etc., improving the flexibility and scalability of the system. In addition, it can also support remote I/O modules up to 12 kilometers away from the host.

Customized configuration: With programmable control interfaces, it supports users to customize configuration and control according to specific application requirements.

Servo control: As a servo amplifier or inverter, it is mainly used to drive servo motors, achieve precise position, speed, and torque control, and is suitable for industrial automation applications that require high precision, high dynamic performance, and low noise, such as production lines, robot control, machine tools, etc.
