F0-08ADH-1 AutomationDirect

F0-08ADH-1 AutomationDirect Controller module

Product  Description：

The F0-08ADH-1 is an 8-channel analog current input module. It is engineered to interface with field sensors that output standard industrial current signals. This module is unique because it offers 16-bit resolution, providing significantly higher precision than standard 12nd-bit or 13-bit modules. It is a "plug-and-play" component that fits into the single expansion slot of a DL05 PLC or any of the four expansion slots available in a DL06 PLC.

Product Parameters

• Number of Channels: 8 single-ended current input channels

• Input Range: $0$ to $20 \text{ mA}$ or $4$ to $20 \text{ mA}$ (software selectable)

• Resolution: 16-bit ($1$ part in $65,536$)

• Input Impedance: $125 \text{ \Omega}$

• Maximum Continuous Overload: $\pm 45 \text{ mA}$

• Accuracy: Maximum $\pm 0.1\%$ of full scale at $25^\circ\text{C}$

• Conversion Rate: All 8 channels are updated per PLC scan

• Isolation: $500 \text{ VDC}$ between the analog inputs and the PLC backplane

• Power Consumption: $25 \text{ mA}$ at $5 \text{ VDC}$ (from the PLC base) and $50 \text{ mA}$ at $24 \text{ VDC}$ (from an external power supply)

• Connector Type: Removable 10-position terminal block

Product Advantages

• High Precision: The 16-bit resolution allows for extremely fine measurements, which is critical for applications involving chemical dosing, precision pressure monitoring, or high-accuracy level sensing.

• Space Efficiency: Providing 8 channels in a single OptionSlot allows users to maximize the I/O count of the compact DL05/06 bases without increasing the physical footprint of the control panel.

• Cost-Effective: It offers high-end analog performance usually found in larger, more expensive PLC platforms at a fraction of the cost.

• Ease of Installation: The removable terminal block allows for pre-wiring or quick replacement of the module without disconnecting individual field wires.

• Flexible Scaling: The module is easily configured through the DirectSOFT programming environment, allowing for quick setup of the $4-20 \text{ mA}$ or $0-20 \text{ mA}$ ranges.

Important Considerations and Precautions

• External Power Requirement: This module requires an external $24 \text{ VDC}$ power supply to operate the analog circuitry. It cannot function solely on the power provided by the PLC backplane.

• Common Ground: Since the inputs are single-ended, all 8 channels share a common return (COM). Care must be taken to avoid ground loops when connecting multiple instruments.

• Shielding: To maintain the high 16-bit accuracy and prevent electromagnetic interference (EMI), it is highly recommended to use shielded twisted-pair cable for all analog signals and to ground the shield at the source or the PLC end (but not both).

• Slot Compatibility: Ensure the firmware of your DL05 or DL06 base is up to date to ensure full compatibility with the high-resolution features of this module.

• Environment: Avoid installing the module in environments with high vibration or extreme temperature fluctuations that exceed the specified operating range ($0^\circ\text{C}$ to $60^\circ\text{C}$).

Product Applications

The F0-08ADH-1 is widely used in industries requiring high-density data acquisition and precise process control.

• Water and Wastewater: Monitoring flow rates, chemical levels, and pressure sensors across multiple tanks using a single compact PLC.

• HVAC Systems: Precise temperature and humidity monitoring using $4-20 \text{ mA}$ transmitters to optimize energy efficiency in large buildings.

• Oil and Gas: Remote monitoring of pipeline pressure and storage tank levels where high resolution is needed to detect small changes or leaks.

• Food and Beverage: Controlling ingredient mixing and pasteurization processes where exact current feedback from sensors is vital for product quality.

• Machine Building: Integrating multiple analog feedback signals from hydraulic or pneumatic systems into a small control cabinet.
