WOODWARD 9905-970 Analog Input Module is an industrial grade analog signal acquisition module produced by Woodward, widely used in steam turbine and gas turbine control systems as an extension module for 505 series, MicroNet or Atlas II series control systems.

product overview

This module supports multi-channel analog input signal acquisition and is suitable for commonly used voltage and current signals in industrial fields, such as 0-5V, 0-10V, 4-20mA, etc. It has the characteristics of high precision, strong anti-interference ability, and high stability. Usually used as the signal input part in the core control system, it communicates with the main controller through the backplane bus.

major function 

Collect analog signals, such as temperature, pressure, position, current and other sensor outputs;

Provide multi-channel input capability, supporting 8 or 16 signal channels (depending on specific configuration);

Support signal isolation to enhance the system's anti-interference capability;

Communicate with the main control module through the backplane interface without the need for separate power supply;

Support diagnostic functions such as signal open circuit and short circuit detection.

Technical Characteristics

- Input type: Supports standard current (such as 4-20mA) or voltage signal (such as 0-10V)

Resolution: 12 bits or higher

- Isolation method: Isolation between the channel and the main control circuit
