Application Scenarios
Exclusively used in oil and gas, petrochemical, metallurgy, and power generation facilities for controlling turbo-generators and industrial turbines.
Performance Parameters
- I/O Configuration: 16 contact inputs (4 fixed, 12 programmable) and 6 programmable current inputs (4-20mA).
- Output: 0-10V DC analog output for driving actuators and valves.
Material Composition
Comprises a series of printed circuit boards housed in a secure, module-style enclosure designed for control room panel integration.
Structural Characteristics
Weighs approximately 6.5 kg with a modular structure. Features dual operational modes: Programming Mode for configuration and Run Mode for automated control.
Working Principle
Utilizes high-precision algorithms to process sensor inputs and execute complex control logic, such as critical speed avoidance and valve limiting, to safely regulate turbine inlet valves.
Installation Requirements
Designed for control room panel mounting. Ensure ambient temperature and humidity remain within specified limits.
Usage Precautions
All field wiring must remain clear of enclosure latching areas and be securely fastened. Always disconnect power before servicing the unit.
