D4-04AD | Automation Direct 4-channel Analog-to-Digital Input Module

The D4-04AD 4-channel Analog-to-Digital Input Module is a specialized component designed to facilitate the integration of analog signals into digital control systems, particularly in industrial automation environments. This module is engineered to convert analog input signals into a digital format that can be processed by a Programmable Logic Controller (PLC), making it an essential tool for systems that require precise monitoring and control of analog data.

Functionally, the D4-04AD serves as an interface between analog devices, such as sensors or transducers, and the digital processing capabilities of a PLC. By converting continuous analog signals into discrete digital data, this module enables the PLC to interpret and act on the input, ensuring accurate and reliable control of industrial processes. This capability is crucial in applications where real-time monitoring and precise adjustments are necessary, such as in temperature control, pressure monitoring, or flow measurement systems.

The D4-04AD module is fully compatible with the DL405 PLC series, providing seamless integration with existing control systems within this family. This compatibility ensures that the module can be easily incorporated into a variety of setups without the need for extensive modifications or additional components. The module’s design also allows for straightforward installation, minimizing downtime during system upgrades or maintenance.

The D4-04AD features four analog input channels, each capable of independently converting an analog signal into a digital format. This multi-channel capability allows the module to handle multiple inputs simultaneously, making it ideal for applications that require the monitoring of several parameters at once. The module’s ability to read all four channels in a single scan ensures that data is processed efficiently, providing real-time updates to the PLC and enabling rapid response to changing conditions.

To accommodate different types of analog signals, the D4-04AD is equipped with six jumper switches located on the rear of the module. These jumper switches allow for the configuration of the input signal range, giving users the flexibility to tailor the module to their specific application requirements. Whether the input signals are voltage or current-based, the D4-04AD can be adjusted to accurately convert the data into a format that the PLC can process.

In addition to jumper switches, the D4-04AD module also includes four DIP switches, which are used to select the data format output to the PLC. Users can choose between standard binary format or two’s complement format, depending on the needs of their application. This flexibility in data formatting ensures that the module can be customized to meet the specific requirements of different control systems, enhancing its versatility and utility in a wide range of industrial settings.

The D4-04AD is also designed with future-proofing in mind, as it can be replaced with the F4-04AD module when necessary. However, it is important to note that the F4-04AD module requires specific configuration settings to match the functionality of the D4-04AD. This feature ensures that users can upgrade their systems without losing compatibility or functionality, allowing for smoother transitions during system updates or expansions.

Overall, the D4-04AD 4-channel Analog-to-Digital Input Module is a robust and versatile component that plays a critical role in the conversion of analog signals for digital processing by a PLC. Its compatibility with the DL405 series, combined with its configurable input ranges and selectable data formats, makes it an ideal choice for a wide variety of industrial automation applications. The module’s ability to efficiently process multiple inputs in real-time ensures that control systems can operate with high precision and reliability, making it a valuable addition to any industrial control system that relies on accurate analog data processing. Whether used in new installations or as part of an upgrade to existing systems, the D4-04AD is engineered to deliver consistent and dependable performance in demanding industrial environments.
