[DX120] Controller for HVAC (AHU, Constant temp & humidity unit, Dehumidifier, etc.) - 4COMP
- [DX120] Controller for HVAC (AHU, Constant temp & humidity unit, Dehumidifier, etc.) - 4COMP
- - Controls temperature and humidity simultaneously - up to 6 loops of separate step operations
- Operates altenately up to 4 compressors and 8 heaters and backups
- Prevents frequent starting caused by low hunting with a low pressure switch of compressors
- Starts the compressors sequentially, pumps down, and prevents restarting -
- High Performance RISC Micom and Digital Calibration
A high performance RISC micom integrates operations of various HVAC systems
and controls digitally and precisely. DX120 handles the instructions
really fast and reduces the risks with high sample rates. It also
provides a digital calibration which meets the requirements of
conditions.
Large Display and Easy-To-Use User Interface
A 5" LCD of 240X128 resolution supports the multilingual(English,
Japanese, Chinese, and Korean language) texts
and images for users. Any operators can select all the menus by
following the steps on the screen. It is as easy as your fingertips.
Compact Size, Simple Operation, and Intelligent Multifunctions for Various HVAC Systems
Like a Swiss army knife,
it is a very small and strong one for multipurposes. Integrating
modules of control and display makes it possible to be compact and
reliable. It can be installed almost everywhere, even at small spaces,
and applied to various HVAC systems(AHU, temperature, humidity,
dehumudification, and etc.). With the real-time information on the
screen and simple operation as well as intelligent multifunctions,
operators can handle the situations without problem and save the time,
money, and efforts for maintenance. DX120 is a real small giant ever
made.
Trip Data Log
DX120 records the important data such as trip and traces up to 200
events. It provides the useful information for analysis and
troubleshooting including history while tripped.
Power Relays and Noise-Free Solutions
Small and reliable power relays are used for output signals. DX120
insulates digital I/O signals completely to block the signals from
outside affecting the mainboard. There are safety functions in CPU.
Brownout watches the control power in real time and watchdog checks the
status continuously(every 32msec) and makes it recover from CPU down by
noise automatically.
