Product Dimensions：

The C0-11DRE-D serves as the central processing unit and base module for a CLICK PLUS control system. It features a built-in micro USB port for programming and configuration, an Ethernet port, and a choice of serial ports, making it highly connected for its size. The "DRE" designation indicates its specific internal I/O configuration, which features a mix of DC inputs and Relay outputs. The module supports wireless connectivity (Wi-Fi and Bluetooth) for data logging, monitoring, and programming, which is a rare feature in controllers of this class. It can operate as a standalone controller or can be expanded by stacking additional CLICK I/O modules to the right of the CPU.

Product Parameters

Product Series: CLICK PLUS
Module Type: Micro PLC CPU with built-in I/O
Input Power Requirements: $24 \text{ VDC}$ , typically drawing around $140 \text{ mA}$ maximum depending on connected expansion modules.
Built-in Digital Inputs: 4 DC inputs, rated for $24 \text{ VDC}$ (sink or source configuration).
Built-in Digital Outputs: 4 Relay outputs, rated up to $240 \text{ VAC}$ or $30 \text{ VDC}$ at $2.0 \text{ A}$ per channel.
Communication Ports: 1 10/100 Mbps Ethernet port (RJ45), 1 Micro USB programming port, and built-in Wi-Fi/Bluetooth capabilities.
Protocol Support: Modbus TCP (via Ethernet) and Modbus RTU (via optional serial ports or Wi-Fi), plus MQTT for cloud connectivity.
Memory Capacity: 50KB of user memory, capable of storing up to 8,000 steps of ladder logic.
Mounting: Standard $35 \text{ mm}$ DIN rail or surface panel mounting.
Environmental Rating: IP20, suitable for installation within an enclosure.

Product Advantages

A standout advantage of the C0-11DRE-D is its Wireless Programming and Connectivity. The integrated Wi-Fi allows technicians to upload or download programs and monitor the system remotely without opening the control cabinet door, improving safety and convenience. The Versatile Output Stage utilizes relay outputs, enabling the module to directly switch AC or DC loads with higher current demands than standard transistor outputs can handle.

The Cost-Effective Scalability is another major benefit; the free programming software significantly lowers the total cost of ownership, while the modular design allows users to expand the system only as needed. Furthermore, its IoT Readiness with built-in MQTT protocol support means this micro PLC can push data directly to cloud platforms or SCADA systems without requiring an expensive intermediate gateway.

Important Considerations and Precautions

When installing the C0-11DRE-D, it is critical to observe the Relay Contact Lifespan Limitations. Because these are mechanical relay outputs, switching highly inductive loads (like large solenoids or motors) will cause contact arcing, which shortens the relay's life; installing external surge suppression (RC networks for AC or flyback diodes for DC) across the load is highly recommended. Ensure Proper Power Supply Filtering is used, as noise on the $24 \text{ VDC}$ supply line can cause communication disruptions, particularly over Wi-Fi.

During wiring, never exceed the Maximum Current Specifications of $2 \text{ A}$ per relay channel to prevent trace damage on the internal circuit board. Since this unit features built-in wireless capabilities, consider Signal Interference and Antenna Placement if mounting inside a solid metal enclosure; an external antenna or a plastic window may be necessary to ensure a stable Wi-Fi connection. Finally, always back up your ladder logic project to a PC, as memory corruption can occur if power is lost during a firmware update.

Product Applications

The AutomationDirect C0-11DRE-D is ideal for small machine control and remote monitoring applications.

Packaging Equipment: Controlling small bagging machines, box tapers, and simple conveyor indexing setups.
Pump Control Systems: Managing alternating duplex pump stations, water tank level controls, and pressure monitoring.
HVAC and Environmental Control: Sequencing small air handling units, greenhouse ventilation, and localized temperature regulation.
Remote Telemetry (RTU): Utilizing Wi-Fi or Ethernet to log data from remote sensors and send it back to a central SCADA system.
Lighting and Building Automation: Managing automated timers for industrial facility lighting, security gates, and access controls.
