Diesel Compressor Controller / DK-30

The DK-30 is a high-tech product providing control and protection of diesel engine driven,
screw or piston type air compressors. The controller incorporates all functions needed in
a compressor control panel. Thus no additional modules are necessary resulting in lower
panel cost.
The controller features full engine protection and instrumentation through analog and
digital inputs and outputs. It acts also as an overspeed protection relay protecting the engine
from overspeeding. In order to prevent battery drain, in STOP mode, the controller turns
completely off, consuming zero current. The engine rpm is read through the magnetic pickup
sender installed on the engine flywheel.

FEATURES
• Automatic operation via output pressure • 6 programmable digital outputs
• Load solenoid control • 6 programmable digital inputs
• Analog speed control output • 3 programmable engine analog sender inputs
• Multiple compressor support • 2 air pressure sensor inputs
• Comprehensive engine instrumentation • 2 air temperature sensor inputs
• Detailed engine protection • Adjustable sensor characteristics
• Engine overspeed protection • Logic level serial port
• Zero power consumption at rest • MODBUS-RTU communications
• Flexible engine hours calculation algorithm • Password protected front panel programming
• Early start function preventing pressure drop • Low panel depth, easy installation
• History records • Wide operating temperature range
• 5 independent service counters • Sealed front panel (IP65 with gasket)
• Magnetic pickup input

Electric Compressor Controller / DK-45 MK2

DK-45 is a high-tech product providing control of screw or piston type air compressors driven
by electric motors. The unit incorporates all functions needed in a compressor control panel;
thus, it eliminates the need for additional modules, resulting in lower panel cost.

The unit is directly supplied from the 400/230V utility network. It provides fail contact and
sensor supplies internally, removing the need for a supply transformer in the panel.

FEATURES
• Graphical LCD screen: 128x64 pixels, 2.9” • Displays utility mains voltages
• Automatic operation from output pressure • No external transformer needed
• Voltage protection relay function • Star / Delta start-up
• Phase order protection function • Frequency inverter driving capability
• Flexible motor hours calculation algorithm • Load solenoid control
• 0-10V Analog speed control output • 5 programmable relay outputs
• Multiple compressor support • Optically isolated, programmable digital inputs
• Early start function preventing pressure drop • 2 pressure sensor inputs
• Dryer control function • 2 temperature sensor inputs
• Event records • Adjustable sensor characteristics
• 5 independent service counters • USB communication port
• Supports various topologies • RS-485 MODBUS communication
• Wide operating temperature range • Password protected front panel programming
• Sealed front panel (IP65 with gasket) • Low panel depth, easy installation
