AutomationDirect D0-06DD2-D PLC Controller

The AutomationDirect D0-06DD2-D is a DL06 series micro programmable logic controller offering a complete self-contained control system with integrated CPU, power supply, and I/O within a single compact housing. Powered by 12-24 VDC, this PLC provides 20 DC inputs and 16 DC sourcing outputs, making it suitable for a wide range of industrial automation applications requiring reliable control in a cost-effective package.

Technical Specifications

The D0-06DD2-D features 20 DC inputs supporting both PNP and NPN configurations with current sinking or sourcing capability. The inputs operate at 12-24 VDC and are organized into 5 isolated commons with 4 inputs per common. The first three inputs are configurable for high-speed I/O functions including 7 kHz counter input, pulse catch input, or interrupt input. The module provides 16 DC sourcing outputs operating at 12-24 VDC with maximum 1.0 A per point. Two outputs are configurable for independent CW/CCW pulse train output or step and direction pulse output up to 10 kHz.

Memory capacity totals 14.8K words, comprising 7679 words of program storage in Flash memory and 7488 words of data storage. User data is retained by a built-in super-capacitor for up to 3 weeks, extendable to 5 years with optional battery backup. The PLC supports ladder logic and Sequential Flowchart programming languages. Basic instruction execution time is 0.6 µs, with standard scan time of 1-2 ms per 1K words of logic.

Key Features

• 220 instructions including floating point math and data manipulation

• 8 auto-tuning PID loops

• Real-time clock with calendar

• 2 communication ports: RS232C and RS232C/RS422/485

• 4 expansion slots for I/O or specialty modules

• Removable terminal blocks for simplified wiring

• Supply voltage 10.8-26.4 VDC, 20W maximum

Communication Capabilities

The D0-06DD2-D features dual serial communication ports. The primary RS232C port and secondary configurable RS232C/RS422/485 port support multiple protocols including DirectNET Master/Slave, MODBUS RTU Master/Slave, and ASCII input/output. This connectivity enables integration with HMIs, SCADA systems, and other automation devices. The secondary port configuration flexibility allows adaptation to different communication requirements without additional hardware.

Expandability

While the base unit provides 36 integrated I/O points, the D0-06DD2-D includes four option module slots for system expansion. These slots can accommodate additional I/O modules to increase point count, communication modules for enhanced connectivity, or specialty modules such as high-speed counter boards. This expandability allows the system to grow with application requirements, supporting up to 100 total I/O points when fully configured.

Applications

The DL06 series PLC is deployed in applications including machine control, conveyor systems, packaging equipment, material handling, and general factory automation. The integrated high-speed I/O makes it suitable for applications requiring pulse output for stepper drives or high-speed counting for encoder feedback. The built-in PID loops support temperature control and process regulation without external controllers. The compact brick-style form factor reduces panel space requirements compared to modular systems with similar capabilities.

Environmental and Power

The D0-06DD2-D operates on a supply voltage of 10.8 to 26.4 VDC, accommodating 12V or 24V system voltages. Maximum power consumption is 20W. The unit is designed for industrial environments with appropriate protection against dust and moisture when installed in a suitable enclosure. Operating temperature range and environmental specifications meet standard industrial requirements for control equipment.

Conclusion

The AutomationDirect D0-06DD2-D DL06 PLC provides a cost-effective, feature-rich control solution for industrial automation applications. With 36 integrated I/O points, dual communication ports, expansion capability, and high-speed I/O functions, it offers capabilities comparable to larger systems in a compact package. For machine builders and system integrators seeking a reliable micro PLC, the D0-06DD2-D delivers proven performance.
