Product Description

The D2-16NA provides 16 discrete input points that operate on 110V AC nominal voltage. It serves as an interface between industrial electrical components and the DL205 CPU. To maintain high density in a small footprint, the module uses two common terminals (8 points per common), which simplifies wiring for multi-phase or multi-circuit applications.

Product Parameters

• Number of Inputs: 16 channels.

• Voltage Category: 110V AC.

• Operating Voltage Range: 80 to 132V AC.

• AC Frequency: 47 to 63 Hz.

• Input Current: 8mA @ 100V AC / 10mA @ 132V AC.

• ON Voltage Level: > 80V AC.

• OFF Voltage Level: < 20V AC.

• Response Time: * OFF to ON: 5 to 30 ms.

  • ON to OFF: 10 to 50 ms.

• Commons: 2 isolated commons (8 points per common).

• Connector Type: Removable 19-position terminal block.

Product Advantages

• High Density: Provides 16 input points in a single modular slot, maximizing the I/O capacity of the DL205 base.

• Removable Terminal Block: Allows for the replacement of the module without having to disconnect every individual field wire, significantly reducing maintenance downtime.

• Optical Isolation: Provides 1500V isolation between the field-side AC circuits and the sensitive PLC backplane electronics, protecting the CPU from electrical surges.

• Status Indicators: Features 16 individual LEDs on the front panel for instant visual confirmation of input status and troubleshooting.

• Cost Efficiency: Offers a rugged and reliable AC input solution at a competitive price point compared to other modular PLC systems.

Precautions for Use

• Voltage Matching: Ensure that the input voltage does not exceed 132V AC, as overvoltage can lead to excessive heat and permanent damage to the input optoisolators.

• Leakage Current: If using the module with solid-state sensors (like proximity switches), ensure the sensor’s leakage current is low enough to allow the input to turn “OFF” (must be below 20V AC at the terminal).

• Wiring Safety: Since this module handles high-voltage AC, always turn off the main power before removing the terminal block or handling field wiring.

• Common Terminals: Note that the 16 points are divided into two groups. Ensure the “Common” terminals (C1 and C2) are correctly wired to the neutral or return side of your AC circuit.

Product Applications

• Safety Interlocks: Monitoring the status of emergency stop buttons and safety gate limit switches in a factory environment.

• Machine Control: Sensing the position of pneumatic cylinders via AC-rated reed switches.

• Motor Control Centers (MCC): Receiving feedback signals from motor starters and contactors to confirm “Running” or “Tripped” status.

• Operator Interface: Interfacing with standard 110V AC industrial pushbuttons and selector switches on a control panel.

• Material Handling: Detecting the presence of items on a conveyor line using AC photo-eye sensors.
