woodward Peak 150 Digital Control for Steam Turbines Peak150.The Woodward Peak 150 is a low-cost, compact digital controller for steam turbines with a wide range of functions and features for steam turbine control of driven mechanical loads, as summarized below:
woodward Peak 150 Digital Control Product Overview：
Application: Designed for control of steam turbines driving mechanical loads, providing speed control (NEMA D) with remote speed control signal input (4 - 20mA).
Product Features: Easy to operate, start-up steam supply valve needs to be opened manually or otherwise, after reaching idle speed the Peak 150 system takes over control and can be accelerated automatically or manually to the minimum governor speed; with two-speed control dynamics and over-speed trip test function; optional Modbus communication function can be used to communicate with programmable logic controllers or distributed control systems; 16-bit. 12MHz microprocessor with a ruggedized speed control signal input (4 - 20mA), 12MHz microprocessor in a rugged NEMA 4 or NEMA - 4X enclosure; front panel operator keypad and rpm/status indicator for easy setup and commissioning via plug-in handheld terminal.

Communication Functions
Communication protocol: Supports Modbus protocol, transmission mode can be configured as RTU or ASCII mode, supports RS-232, RS422 and RS-485 through wiring, can communicate with the main control unit to report information such as speed, speed set point, alarms and shutdown conditions.
Input and Output Specifications
Inputs: Includes two magnetic pickup inputs (high signal selection, minimum input voltage 1Vrms, frequency range 200Hz - 15kHz), one analog input (remote speed setting signal, 4 - 20mA or 1 - 5Vdc selectable), and eight discrete inputs (e.g., functions such as remote speed up/down, emergency stop, and alarm reset).
Outputs: two analog outputs (actual speed output and configurable readout, scalable), one actuator output (4 - 20 or 0 - 200mA selectable), four relay outputs (selectable normally open or normally closed contacts for functions such as stop, alarm, etc.).
Operation Panel and Environmental Specifications
Operation panel: six key switches (for functions such as speed up, speed down, emergency trip, etc.) and five digital LED displays for speed indication, and six LED indicators for various statuses.
Environmental specifications: Operating temperature range of - 25 to + 60°C, storage temperature range of - 40 to + 85°C, in line with a variety of military and industrial standards, through the relevant certificates, different models have different input power requirements (such as 24Vdc, 90-150Vdc or 88-132Vac, etc.), the maximum power consumption of 38W, dimensions: 483mm * 310mm *105mm.
