F2-8AD4DA-2 AutomationDirect

F2-8AD4DA-2 AutomationDirect Controller module

Product  Description：

The AutomationDirect F2-8AD4DA-2 is an advanced I/O module designed for use with the DirectLOGIC DL205 Series Programmable Logic Controllers (PLCs). This module is a high-density, multifunction analog module that combines both analog input and analog output capabilities within a single unit.

Product Specifications

• Product Series: DirectLOGIC DL205 PLC

• Module Type: Combined Analog Input and Output Module

• Analog Inputs (AD): 8 channels, single-ended

  • Input Resolution: 14 bits

  • Input Signal Range (Current): $4 \text{ mA}$ to $20 \text{ mA}$ (Source/Sink wiring must be set for each channel via jumpers)

  • Input Signal Range (Voltage): $0 \text{ V}$ to $5 \text{ V}$, $0 \text{ V}$ to $10 \text{ V}$, $\pm 5 \text{ V}$, or $\pm 10 \text{ V}$ (configured via jumpers)

• Analog Outputs (DA): 4 channels, single-ended

  • Output Resolution: 12 bits

  • Output Signal Range (Current): $4 \text{ mA}$ to $20 \text{ mA}$

  • Output Signal Range (Voltage): $0 \text{ V}$ to $5 \text{ V}$, $0 \text{ V}$ to $10 \text{ V}$, $\pm 5 \text{ V}$, or $\pm 10 \text{ V}$ (configured via jumpers)

• Conversion Rate (Total): Approximately $20 \text{ ms}$ for all 12 channels (8 AD and 4 DA)

• Wiring Connection: Requires a removable terminal block (sold separately, typically part number F2-CM1) for field wiring.

• Module Slot Requirement: Occupies a single slot in the DL205 base.

• Power Consumption: Requires power from the DL205 backplane.

Product Advantages

• High Channel Density: The F2-8AD4DA-2 provides a significant number of analog I/O points (8 inputs and 4 outputs) in a single module slot, conserving valuable space within the DL205 chassis.

• Flexibility in Signal Range: Both the input and output channels offer multiple voltage and current signal ranges ($4 \text{ mA}$ to $20 \text{ mA}$, $0 \text{ V}$ to $10 \text{ V}$, etc.), which are configurable using on-board jumpers. This allows the module to interface with a wide variety of industrial sensors and actuators.

• Cost-Effective Solution: Combining both input and output functionality into one unit typically offers a more economical solution compared to purchasing separate analog input and output modules.

• High Resolution: The 14-bit input resolution provides excellent precision for monitoring process variables, while the 12-bit output resolution offers good control fidelity.

• Ease of Integration: It is specifically designed for the DL205 platform, ensuring seamless integration and configuration using the DirectSOFT programming software.

Important Considerations (Precautions)

• Jumper Configuration: The module requires careful configuration of numerous on-board jumpers to select the correct signal range (voltage or current) and wiring type for each channel. Incorrect jumper settings will result in improper readings or potential damage.

• Wiring Terminal: The module itself does not include the wiring terminal block (F2-CM1), which must be purchased separately. Ensure the correct terminal block is used for secure and reliable field wiring.

• Isolation: The F2-8AD4DA-2 typically features a non-isolated or group-isolated design. For installations where channel-to-channel isolation or high noise immunity is critical, external isolation measures or modules with full channel isolation may be necessary.

• Noise and Shielding: Due to the sensitive nature of analog signals, all field wiring must use shielded twisted-pair cables, and proper grounding techniques must be strictly followed to minimize electrical noise interference and ensure measurement accuracy.

• Scaling: Raw data from the analog input channels must be appropriately scaled within the PLC program (using DirectSOFT instructions) to represent meaningful engineering units (e.g., °C, PSI, gallons per minute).

Product Applications

The F2-8AD4DA-2 module is essential for applications requiring both the measurement and control of continuous process variables within the DL205 system.

• Process Control Loops: Used in industries like water treatment, food and beverage, and chemical processing to monitor temperature, pressure, flow, and level (inputs) and to control valves or variable speed drives (outputs).

• Heating, Ventilation, and Air Conditioning (HVAC): Monitoring air and water temperatures and humidity, and controlling damper positions or hot water valves.

• Machine Control: Controlling the speed of motors via variable frequency drives (VFDs) and reading linear position transducers or load cell signals.

• Data Acquisition and Logging: Collecting high-resolution analog data from various sensors for quality assurance and historical data logging.
