WOODWARD 3161 LIO Local Input/Output Module

Product Brief Description

Woodward 3161 LIO is a local I/O expansion module designed for Woodward control systems. It collects field digital and analog signals, converts them into internal bus data for the main controller, and outputs drive commands to field actuators. This rugged industrial module extends I/O capacity for prime mover control, commonly used as spare parts for gas turbine, steam turbine and engine genset control cabinets.

• Analog input, analog output, digital input and relay digital output channels
• Signal acquisition of speed sensors, pressure, temperature and vibration transmitters
• Receives control commands from main CPU and outputs analog signals to electro-hydraulic actuators
• Built-in channel fault detection, short-circuit and open-circuit diagnosis for each I/O point
• High-speed internal bus communication to exchange real-time data with master controller
• Onboard LED indicators for power, communication status and individual channel alarms
• Supports hot replacement in qualified redundant system configurations
• Wide temperature range and high EMC performance for harsh industrial cabinet environments

Application Scenarios

• Gas turbine and steam turbine control systems
• Gas engine and diesel generator set governor cabinets
• On-site captive power plants and combined heat & power units
• Oil & gas pipeline compressor prime mover control
• Control system retrofits, spare replacement and emergency maintenance
