Description

AutomationDirect D2-16NA Discrete Input Module

Product Dimensions：

The AutomationDirect D2-16NA is a discrete input module belonging to the DL205 series of Programmable Logic Controllers (PLCs). It is a high-density AC input module designed for industrial control systems that require monitoring of standard 110-220V AC signals.

1. Product Description

The D2-16NA provides 16 AC input points in a single-slot module. It is designed to interface with field devices such as limit switches, pushbuttons, and sensors that operate on AC voltage. This module is compatible with all DL205 local bases and remote I/O systems.

2. Technical Specifications (Parameters)

3. Key Advantages

• High Density: Offering 16 points in a single slot allows for a smaller PLC footprint and lower hardware costs.

• Removable Terminal Block: The module features a removable connector, allowing you to replace the module without disconnecting the field wiring, which significantly reduces downtime.

• Optically Isolated: The internal PLC circuitry is protected from high-voltage field spikes via optical isolation.

• Status Indicators: Includes 16 logic-side LED indicators for easy visual troubleshooting of input states.

4. Important Considerations (Precautions)

• AC Voltage Only: Do not apply DC voltage to this module as it is designed specifically for AC waveforms.

• Leakage Current: When using sensors with leakage current (like certain proximity switches), ensure the leakage is below the module’s “Off” threshold (typically < 20VAC) to avoid “ghost” signals.

• Thermal Management: If all 16 inputs are active simultaneously at high ambient temperatures, ensure the PLC cabinet has adequate ventilation.

• Fused Wiring: It is highly recommended to use external fuses for each common or individual input to protect the module from short circuits in the field.

5. Typical Applications

• Motor Control Centers (MCC): Monitoring the status of motor contactors or overloads operating on 110V/220V AC.

• Facility Management: Interfacing with lighting circuits and HVAC dampers.

• Packaging Machinery: Connecting to standard AC-powered limit switches and emergency stop buttons.

• Material Handling: Detecting pallet presence using AC-powered photoelectric sensors.
