DATAKOM DK-30 Diesel Compressor Controller

Description

DATAKOM DK-30 is a high-performance diesel compressor controller, specifically designed to manage and protect diesel engine-driven air compressors, including both screw and piston types.

Features:

Pressure Management:

• Automatically starts and stops the engine based on output pressure levels.
• Utilizes a PID-controlled analog speed output for maintaining stable pressure.

Load Solenoid and Solenoid Outputs:

• Built-in controls for operating load solenoids.
• Capable of handling solenoid-operated compressor valves.

Early Start Functionality:

• Predicts air consumption trends and starts the compressor before pressure drops below the critical level.

Multi-Unit Support:

• Integrates support for up to 8 compressors in the same system for synchronized operation.

Comprehensive Protection:

• Protects engines from overheating, low oil pressure, overspeed, and other critical faults.

Data Logging and Monitoring:

• Keeps detailed event history for troubleshooting and analysis.
• Equipped with five service counters to help monitor and schedule regular maintenance.

Zero Power Consumption in STOP Mode:

• Consumes no battery power when the compressor is not in operation, ensuring longer battery life.

Modbus RTU Communication:

• Allows seamless integration with remote monitoring systems via serial ports.

Instrumentation and Input/Output:

Inputs:

• Magnetic pickup for speed sensing (0.5–30V AC; 0–10,000 Hz).
• Configurable digital and analog inputs for engine sensors (oil pressure, coolant temperature, fuel level, etc.).
• 4–20mA pressure sensor compatibility for precise pressure readings.

Outputs:

• Semiconductor-based MOSFET outputs for robustness.
• Charge alternator excitation output for battery charging.

Display and Interface:

• Clear LED/LCD screen for operational status, fault conditions, and pressure levels.
• Easy-to-navigate menu structure for parameter adjustments.
