Description
AutomationDirect F0-08ADH-1 Input Module
Product Dimensions:
The F0-08ADH-1 is an 8-channel analog input module specifically designed for the DL05 and DL06 series of Programmable Logic Controllers (PLCs) from AutomationDirect. It provides high-resolution current signal monitoring in a compact form factor.
Product Specifications (Parameters)
| Feature | Specification |
| Number of Channels | 8 |

| Resolution | 16-bit (1 part in 65,535) |
| Input Impedance | 250 $\Omega$ ($\pm$ 0.1%, 1/2W) |
| Conversion Rate | 1.25 ms per channel (10 ms for all 8) |
| Accuracy | $\pm$ 0.1% of full scale at 25°C |
| Isolation | 1500V between field wiring and logic |
| External Power | 24 VDC ($\pm$ 10%) at 50 mA |
| Connection Type | Removable terminal block (included) |
Key Product Advantages
-
High Precision: With 16-bit resolution, it is ideal for applications requiring fine-tuned monitoring of pressure, flow, or temperature.
-
Space Efficient: It plugs directly into the option slots of DL05 or DL06 PLCs, adding significant I/O density without increasing the footprint.
-
Cost-Effective: Offers a lower price-per-channel ratio compared to many modular PLC competitors.
-
Ease of Maintenance: The removable terminal block allows you to replace a module without rewiring the entire system.
-
Filter Options: Includes digital filtering to stabilize “noisy” signals from field transmitters.
Important Considerations (Notes)
-
Power Supply: This module requires an external 24 VDC power supply to power the onboard analog circuitry. It cannot run solely on the PLC backplane power.
-
Jumper Settings: You must manually set internal jumpers to choose between 0–20 mA and 4–20 mA ranges before installation.
-
Shielding: To prevent Electromagnetic Interference (EMI), always use shielded twisted-pair cabling and ground the shield at the power supply end.
-
Slot Limitation: While the DL06 has two slots, ensure your total power budget (from the PLC’s internal 5V supply) supports all installed modules.
Typical Applications
The F0-08ADH-1 is widely used in process control environments, including:
-
Water Treatment: Monitoring flow meters and pH sensors.
-
HVAC Systems: Reading pressure transducers and humidity sensors.
-
Food & Beverage: Tracking tank levels via 4–20 mA ultrasonic sensors.
-
Manufacturing: Monitoring motor current or valve positions for feedback loops.
