The D2-09B-1 is a high-performance I/O base module designed for Automation Direct’s DirectLogic DL205 series PLCs. It serves as the central backbone for mounting up to 9 I/O modules, power supplies, and communication interfaces, providing a compact and flexible platform for industrial control systems. With integrated power distribution, backplane communication, and DIN rail mounting, this base simplifies system integration and reduces wiring complexity.
-
Physical Specifications
- Dimensions: 220mm (length) × 76mm (width) × 60mm (height)
- Weight: Approximately 350g
- Mounting: Standard DIN rail mounting (35mm)
- Module Slots: 9 slots for installing DL205 series I/O modules, CPU modules, or communication modules
-
Electrical Characteristics
- Power Input: 100-240VAC (via external power supply, e.g., D2-PWR-240)
- Power Distribution: Provides 5VDC (1.5A max) to modules via backplane
- Backplane Communication: Proprietary parallel bus for high-speed data transfer between modules
- Isolation: 250VAC isolation between power input and backplane
-
Environmental Parameters
- Operating Temperature: 0°C to 55°C (32°F to 131°F)
- Storage Temperature: -20°C to 70°C (-4°F to 158°F)
- Humidity: 5%-95% RH (non-condensing)
- Vibration Resistance: Complies with IEC 60068-2-6 (10-57Hz, 0.75mm double amplitude)
- Shock Resistance: Complies with IEC 60068-2-27 (15g, 11ms)
-
Compatibility
- Compatible with all DL205 series modules, including:
- CPU modules (e.g., D2-250-1, D2-16ND1)
- I/O modules (e.g., D2-08TA, D2-16NA)
- Communication modules (e.g., H2-ECOM)
- Requires a compatible power supply (sold separately)
-
High Expansion Capacity
Supports up to 9 modules, allowing flexible configuration of I/O points, communication interfaces, and special function modules to meet diverse application needs.
-
Integrated Power Distribution
Distributes 5VDC power to installed modules via the backplane, eliminating the need for separate power wiring and simplifying system design.
-
Fast Backplane Communication
Proprietary parallel bus ensures high-speed data exchange between modules, reducing signal delay and improving system response time.
-
Compact and Durable
Industrial-grade construction with a compact footprint saves space in control cabinets, while rugged design ensures reliability in harsh environments.
-
Easy Installation
DIN rail mounting simplifies installation and maintenance; modules can be quickly inserted or removed without tools, reducing downtime during upgrades.
-
Industrial Automation Lines
Serves as the core I/O platform for controlling conveyors, packaging machines, and assembly lines, integrating sensors, actuators, and controllers.
-
Machine Control Systems
Used in CNC machines, injection molding machines, and printing presses to connect I/O devices and implement precise control logic.
-
Process Monitoring
Integrates analog and digital I/O modules to monitor temperature, pressure, and flow in chemical, food, and pharmaceutical production.
-
Building Automation
Connects HVAC, lighting, and security system components, enabling centralized control and monitoring of building facilities.
-
Energy Management
Interfaces with power meters, relays, and controllers to monitor and manage energy distribution in factories and commercial buildings.
-
Power Supply
- Use only compatible power supplies (e.g., D2-PWR-240) to ensure stable 5VDC output to modules.
- Check total power consumption of installed modules to avoid exceeding the base’s 1.5A current limit.
-
Module Installation
- Ensure modules are fully inserted into the base to prevent poor backplane contact and communication failures.
- Do not mix DL205 modules with incompatible series (e.g., DL405) to avoid damage.
-
Environmental Protection
- Install the base in a dust-free, dry control cabinet; avoid exposure to corrosive gases or extreme temperatures (>55°C).
- Provide adequate ventilation to prevent overheating when multiple high-power modules are installed.
-
Wiring and Grounding
- Securely ground the base to reduce electromagnetic interference; use shielded cables for I/O connections.
- Tighten terminal screws to prevent loose connections and signal instability.
-
Maintenance
- Power off the system before removing or inserting modules to avoid damaging backplane pins.
- Regularly inspect module connections and clean dust from vents to maintain heat dissipation.
