DK-30 DIESEL COMPRESSOR

CONTROLLER

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.

The “early start” function analyzes the air consumption trend and runs the compressor so that the pressure never falls below the low limit

In order to have a constant output pressure, the controller is capable of governing the engine speed with its analog output driven by a PID loop. The controller supports multi-compressor application up to 8 compressors. The logic level Modbus RTU communication port of the controller allows computer connection providing monitoring and program parameter adjusting.

The controller configuration may be done through the front panel or using the free PC software. The PC software is available for free download at manufacturer’s website. It is possible to monitor and record the controller using the free RAINBOW+ software
