Functional Description

5463-405 is a Discrete Input Module developed by Woodward. This module provides a reliable and efficient way to interface field switches and relays with the LINKnet network, enabling the system to capture and transmit discrete data in a secure and accurate manner.

Installation Process

• Discrete Input Module is designed for easy installation on a DIN rail. It is essential to mount the module securely on the rail to ensure stable operation. Once installed, it must be connected to the LINKnet network and the 24 Vdc power supply for proper functionality.
• The discrete inputs can be wired using the internal +24 V connections or an external 24 V power source, depending on the system design.
• The module features rotary switches that allow users to set the module’s address for both the one’s and ten’s positions. The address settings should be configured according to the application setup and network requirements.

Hot Replacement Capability

• The network cable connections should remain intact during node replacement. To remove the faulty node, pull both terminal blocks out of their headers and carefully detach the node from the DIN rail.
• The address switches of the replacement node should be configured to match the settings of the faulty node to ensure compatibility and proper communication within the network.
• After setting the correct address, the replacement node can be mounted onto the DIN rail. Then, reconnect the terminal blocks into their respective headers.
• Once the replacement node is securely installed, it must be reset through the application program to reinitiate communication with the LINKnet controller module and clear any no message fault that may have occurred during the replacement process.

Troubleshooting

• The module provides power for field contacts through four terminal blocks (TB-5 to TB-8). This power is used to energize the field switches or relays connected to the module. Although TB-2 can also provide input power, it lacks the internal fuse and some filtering capabilities. Therefore, it is recommended to provide external fusing when using this terminal block.
• The state of each discrete input is transmitted through an optoisolator and an LED to the shift register. The LED will illuminate when a contact is closed, providing a visual indication of the input status.
• The module’s processor processes the input data and transmits it via the transceiver to the LINKnet controller module. This ensures that the system controller has real-time access to the state of all connected inputs.

Frequently Asked Questions

What is 5463-405?
It is a discrete Input Module developed by Woodward.

What power options are available for the module?
The Woodward module provides power for field contacts via TB-5 to TB-8 terminal blocks. Additionally, TB-2 can be used to provide input power, though external fusing should be applied in this case, as it does not have the same internal fuse and filtering as other terminals.

How does the module indicate the status of inputs?
Each input state is transmitted through an optoisolator and is visually indicated by an LED. The LED lights up when a contact is closed, providing a clear and immediate visual signal of the input’s status.

What is the troubleshooting process for the module?
Ensure proper power is supplied to the module, especially when using TB-2. The LEDs help diagnose input issues by indicating whether the contacts are closed or open. Ensure that the module’s processor correctly transmits data to the LINKnet controller for further processing.
