| I/O Capacity | 16,384 discrete pts / 1,024 analog pts (via remote I/O) |
| Communication Ports | 2 Ports (RS-232C), Port 2 supports RS-422 |
| Protocols | DirectNET, K-sequence, Modbus RTU (Master/Slave) |
| Execution Speed | 0.1ms per 1k Boolean instructions |
| PID Loops | Up to 16 loops with auto-tuning |
| Built-in Features | Real-time clock/calendar, 24VDC internal power |
3. Key Advantages
-
Advanced PID Control: Supports up to 16 loops, making it ideal for process control like temperature or pressure regulation.
-
Flexible Networking: Dual communication ports allow for simultaneous connection to an HMI and a secondary network like Modbus.
-
Longevity: Part of a legacy series known for extreme durability in harsh industrial environments.
-
Ease of Programming: Uses DirectSOFT programming software, which features an intuitive ladder logic interface.
-
Large Instruction Set: Includes floating-point math, drum sequencers, and bit-of-word manipulation.
4. Safety & Precautions
-
Base Power: Ensure the DL205 base power supply is adequate for the CPU and all attached I/O modules.
-
Battery Maintenance: The DL250-1 uses a lithium battery (D2-BAT-1) to retain memory. Replace this battery every 2-5 years to prevent logic loss during power outages.
-
Port 2 Wiring: Port 2 can be configured for RS-232 or RS-422. Ensure your dip switches and wiring diagrams match your peripheral device to avoid hardware damage.
-
Environment: Operate within the specified temperature range (0°C to 60°C) and ensure the cabinet is free from conductive dust.
5. Typical Applications
The DL250-1 is versatile and commonly used in:
-
Packaging Machinery: Coordinating high-speed sensors and actuators.
-
Water Treatment: Utilizing PID loops for chemical dosing and flow control.
-
Conveyor Systems: Managing complex routing and sorting logic.
-
HVAC Systems: Controlling large-scale industrial boilers and chillers.
-
Data Acquisition: Using Modbus RTU to pull data from power meters or specialized sensors.
