High Performance RISC Micom
A high performance RISC micom integrates operations and controls digitally and precisely. It handles the instructions really fast and reduces the risks with high sample rates.

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.

Operation Status Display
DX230H displays the operation status of a compressor and waiting time.

Compact Size, Simple Operation, and Intelligent Multifunctions for Screw Compressors
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 screw compressors. 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.

Trip Data Log
DX230H records the important data such as trip is recorded and traces up to 160 events. It provides the useful information for analysis and troubleshooting including history while tripped.

Noise-Free Solutions
Digital I/O signals are completely insulated to block the signals from outside affecting the mainboard. There are safety functions in CPU. Brownout monitors the control power in real time and watchdog checks the status continuously(every 32msec) and makes it recover from CPU down by noise automatically.

RS485 port, MODBUS RTU stnadard protocol, MMI software, and automatic interface are supported.
