DESCRIPTION
DK-70 is a next generation compressor controller
providing control of a screw or piston type air compressor
driven by electric motor.
DK-70 offers wide internet-based communication
capabilities satisfying tomorrow's needs. It allows remote
monitoring and control over internet. A mobile phone app
is also available for ease of use.
The unit incorporates all functions needed in a
compressor control panel, eliminating the need for extra
modules in the panel and lowering panel cost.
The early start function analyzes the air consumption
trend and starts the compressor before the pressure falls
below the low set limit.
Using the Weekly Schedule Program and Pressure
Calendar functions, the compressor can be programmed
to start on given hours and days of the week with user
defined set pressure values.
The unit is supplied from the utility. Fault contacts and
senders are internally supplied, eliminating the need for a
supply transformer in the panel.
The 2.9", 128x64 pixel LCD screen displays values in
bigger size with graphic support.
The controller is designed to conform to highest industrial
standards in safety, vibration, EMC and environmental
conditions.
Firmware updates can be done easily via the USB port.
The device can be monitored and programmed via USB,
RS-485, Ethernet, WIFI and GPRS using the Windows
based free PC software.
Rainbow Scada web service enables central remote
monitoring and control of an unlimited number of
compressors.
