AutomationDirect D0-06DD1-D 12-24 VDC DL06 PLC

Description

Key Technical Specifications

The current AutomationDirect cut sheet confirms the 20-input/16-output architecture, 12–24 VDC supply, 14.8K-word memory, two serial ports, four-module expansion capacity, and 7 kHz/10 kHz high-speed I/O capabilities.

One important wiring distinction is that D0-06DD1-D uses sinking outputs, while its 20 inputs can be wired as either sinking or sourcing inputs. The outputs share a common, so field wiring must be checked before substituting this model for another DL06 variant.

Product Introduction

The AutomationDirect D0-06DD1-D is a DirectLOGIC DL06 micro PLC for machine control, material handling, process equipment, and compact automated systems. It integrates 20 DC inputs and 16 sinking DC outputs into a single controller and accepts up to four optional expansion modules.

For legacy installations, its two serial ports are particularly useful. Port 2 supports RS-232, RS-422, and RS-485 communication and can operate as a MODBUS RTU master or slave. AutomationDirect also documents DirectNET, ASCII, and K-Sequence communication functions.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation

Estimated time: 15–30 minutes

1. Place the machine in a defined safe state.
2. Apply the site’s LOTO procedure.
3. Isolate the 12–24 VDC control supply.
4. Verify zero voltage at the PLC power terminals.
5. Use an ESD wrist strap when handling the controller.
6. Upload and save the existing PLC program.
7. Record the communication parameters.
8. Photograph the existing I/O wiring and option-module arrangement.
9. Record any battery-backed or retentive data that must be preserved.

⚠️ Do not remove the existing controller until the application program has been backed up and verified.

Stage 2 — Removing the Existing PLC

Estimated time: 10–20 minutes

1. Confirm the existing model and hardware revision.
2. Label every field connection.
3. Disconnect the power supply.
4. Disconnect serial communication cables.
5. Remove I/O wiring without pulling on adjacent terminals.
6. Release the mounting hardware.
7. Remove the PLC carefully.
8. Inspect the wiring and terminals for heat damage, corrosion, or loose conductors.

Keep the original controller available until the replacement has completed commissioning.

Stage 3 — Installing D0-06DD1-D

Estimated time: 15–30 minutes

1. Verify the replacement nameplate reads D0-06DD1-D.
2. Confirm the external supply is 12–24 VDC.
3. Confirm that the installed option modules are compatible.
4. Mount the PLC securely.
5. Reconnect the field wiring according to the documented terminal assignment.
6. Reconnect the communication cables.
7. Verify input common wiring.
8. Verify the output common and load wiring.
9. Check that connected loads do not exceed the applicable output-current limits.

⚠️ Do not confuse D0-06DD1-D with the AC-powered D0-06DD1. AutomationDirect lists D0-06DD1 as requiring 120–240 VAC, while the D0-06DD1-D requires 12–24 VDC.

Stage 4 — Power-On & Testing

Estimated time: 20–45 minutes

1. Measure the incoming DC voltage before energizing the PLC.
2. Power the controller with field outputs isolated where practical.
3. Check the PLC status indicators.
4. Connect the programming computer.
5. Verify the PLC model and communication parameters.
6. Restore the validated application program if necessary.
7. Check retentive values and clock settings.
8. Test each input individually.
9. Test outputs without process movement where possible.
10. Verify MODBUS/DirectNET communications.
11. Perform a controlled dry run.
12. Return the equipment to production only after the I/O and communication tests pass.

For MODBUS networks, AutomationDirect specifically documents Port 2 as the DL06 master interface and supports RS-232/RS-422/RS-485 configurations depending on the application.

FAQ

Is D0-06DD1-D a CPU module or a complete PLC?

It is a complete fixed-I/O DL06 micro PLC, integrating the processor, memory, 20 DC inputs, and 16 DC outputs. Expansion modules can be added when additional I/O or communication functions are required.

What is the difference between D0-06DD1-D and D0-06DD1?

The power architecture is the key difference. D0-06DD1-D requires 12–24 VDC, whereas D0-06DD1 requires 120–240 VAC. Both are DL06 controllers with 20 DC inputs and 16 sinking DC outputs.

Are the 20 inputs sinking or sourcing?

The inputs can be configured for either sinking or sourcing field devices, with five isolated input commons and four inputs per common.

Are the outputs sinking or sourcing?

The D0-06DD1-D has 16 sinking DC outputs. This should be checked carefully when replacing a different PLC or a variant with a different output architecture.

Does it support MODBUS RTU?

Yes. The supports MODBUS RTU, and Port 2 can operate as either a master or slave. RS-485 is available for MODBUS applications, while RS-232 and RS-422 configurations are also supported.

Can the PLC perform high-speed motion or counting functions?

Yes, within its documented I/O resource limits. Four inputs support high-speed functions up to 7 kHz, while two outputs support pulse-train functions up to 10 kHz. The exact high-speed configuration must be checked because certain input and pulse-output functions share hardware resources.

What programming software is required?

The manufacturer specifies DirectSOFT32 Version 4.0 or later for the D0-06DD1-D.

Is D0-06DD1-D suitable as a replacement for an existing ?

It can be suitable when the original application uses compatible I/O, power, option modules, communication settings, and program functions. Do not treat the model number alone as proof of drop-in compatibility. Check the existing wiring and configuration before replacement.
