9905-973 is a Linknet 8 Channel Relay Module manufactured and designed by Woodward and used in Gas Turbine Control Systems. The Linknet 8 Channel Relay Module is an electronic device that allows you to control multiple electrical devices using digital signals. It is typically used in projects that require switching on or off various devices remotely or programmatically. The module consists of eight individual relays, each capable of switching a separate electrical circuit. A relay is an electromechanical switch that can control a high-power circuit using a low-power signal. In this case, the relay module allows you to use digital signals (typically from a microcontroller or a computer) to control the switching of the relays. The Linknet 8 Channel Relay Module often interfaces with microcontrollers or other digital control systems via common communication protocols such as GPIO (General Purpose Input/Output) pins or serial communication (e.g., I2C or SPI). This makes it compatible with various development boards and platforms, allowing you to integrate it into your projects easily.

Applications of the Linknet 8 Channel Relay Module include home automation systems, industrial automation, robotics, and any project where remote control or automation of multiple electrical devices is needed. It provides a convenient and reliable way to control multiple circuits without directly connecting to the devices you want to control.


The exact features of the Linknet 8 Channel Relay Module may vary depending on the specific model and manufacturer. However, here are some common features you can expect to find in such a module:

8-channel relay outputs: The module typically offers eight independent relay channels, allowing you to control eight different electrical circuits.

High switching capacity: Each relay channel can handle high-power loads, typically up to a certain voltage and current rating. Common ratings may include 10A at 250V AC or 10A at 30V DC, but this can vary depending on the module.

Digital control interface: The module is designed to be controlled using digital signals, such as GPIO pins or serial communication protocols like I2C or SPI. This enables easy integration with microcontrollers, development boards, or other digital control systems.

Opto-isolation: The relay inputs are often optoisolated, which means they have a separate electrical isolation barrier to protect the controlling circuitry from voltage spikes or noise generated by the relay coil.

LED indicators: Each relay channel may have an associated LED indicator to provide visual feedback on the status of the relay (e.g., whether it is activated or deactivated).

Compact form factor: The module is usually designed to be compact and easily mountable, allowing you to integrate it into your projects conveniently.

What is the maximum voltage and current rating for each relay channel?

The maximum voltage and current rating can vary depending on the specific model of the relay module. Typically, each channel can handle voltages up to 250V AC or 30V DC and currents up to 10A. However, it is essential to consult the manufacturer's documentation or product datasheet for the precise specifications of the module you are using.

Does the module provide feedback on the relay status?

Yes, many relay modules include LED indicators associated with each relay channel. These LEDs provide visual feedback on the status of the relays, indicating whether they are activated or deactivated.

Can I connect high-voltage or high-power devices directly to the relay module?

It is generally recommended to use proper electrical wiring and safety measures when connecting high-voltage or high-power devices to the relay module. The module's specifications will indicate the maximum voltage and current ratings that it can handle. If you are unsure or dealing with high-power circuits, it is advisable to consult an electrician or engineer for guidance.
