AUTOMATION DIRECT C0-4AD2DA-1 Analog I/O Module

Product Dimensions：

The AutomationDirect C0-4AD2DA-1 is a high-performance analog input/output combo expansion module from the popular CLICK PLC series. It is designed to provide a cost-effective and space-saving solution for applications requiring both analog monitoring and control.

Product Detailed Description

The C0-4AD2DA-1 is a modular expansion card that snaps directly onto the right side of any CLICK PLC CPU. This combo module features 4 analog input channels and 2 analog output channels, both operating on a standard current loop signal range (0–20 mA). It is a passive-backplane module that draws its operating power directly from the connected CLICK CPU or system power supply.

Technical Parameters

Product Advantages

• High Efficiency & Low Cost: Combining 4 inputs and 2 outputs into a single narrow slot minimizes both the physical footprint inside the control panel and the overall hardware component cost.
• 13-Bit Resolution: Offers high precision for small-scale automation tasks, allowing for detailed tracking and smooth control loops.
• Removable Terminal Block: Includes a removable 11-point terminal block, which simplifies initial wiring and enables rapid module replacement without disconnecting individual field wires.
• Easy Software Configuration: No complex ladder logic is required to scale the analog signals. The CLICK programming software provides a user-friendly configuration window to scale 0–20 mA straight into engineering units (e.g., Gallons, PSI, °C).

Important Considerations & Precautions

• Current Loop Only: This module is strictly designed for 0–20 mA signals. It does not natively support 4–20 mA (though this can be handled via software scaling) or voltage signals (0–10V).
• Single-Ended Inputs: The inputs share a common return path (0V/COM). Ensure your field transmitters are compatible with a common-ground configuration to avoid ground loops.
• External Power: The module requires an external 24 V DC power supply to power the analog circuitry and loops, in addition to the power it draws from the PLC bus.
• Current Limits: Do not exceed the maximum allowable input current (usually 40 mA) to prevent overheating and permanent damage to the internal 125 \Omega precision resistors.

Product Applications

The C0-4AD2DA-1 is ideal for small to mid-sized process automation projects:

• Pumping Stations: Using the 4 inputs to monitor well levels or pipe pressures, and the 2 outputs to control Variable Frequency Drives (VFDs) regulating pump speeds.
• Environmental Control: Interfacing with humidity and temperature sensors while controlling modulating dampers or heating valves.
• Tank Level Management: Tracking the volume of multiple chemical tanks and driving proportional control valves for precise mixing and dosing.
• OEM Machinery: Integrating affordable analog control into compact, specialized packaging or assembly machines.
