ACC7100 Diesel Air Compressor Controller is used for air compressor with diesel-driven engine in order to realize functions of compressor start/stop, data measurement, maintenance, alarm protection and "three remotes". It has speed regulator function, and CANBUS (SAE J1939) port, which can control various ECU or non-ECU diesel-driven air compressors. It also applies heatable liquid crystal and electronic components resistant to high and low temperature, which are suitable for extremely low or high temperature environments (-40℃~+70℃), so that controller can work reliably under the condition of extreme temperature.

ACC7100 Diesel Air Compressor Controller applies 32-bit ARM micro-processor technology, which can realize functions of precise measurement for many parameters, set-point adjustment, timing and threshold setting etc. A majority of parameters can be adjusted from the control panel. All parameters can be adjusted and monitored on PC by RS485 or USB port. It can be widely used for diesel-driven air compressor control system with compact structure, simple wiring, and high reliability.


132x64 LCD display with backlight; Heatable under low temperature; Optional Chinese, English and other languages; Simple operation interface;

Operation temperature range (-40℃~+70℃), applicable for tough environment occasions;

RS485 communication port realizes "three remotes" function by MODBUS protocol;

CANBUS port can monitor ECU common data (speed, water temperature, load rate, fuel consumption etc.).

DPF regeneration function, which meets Euro V emission standard.

8 ways of analog sensors, 2 ways of fixed resistance type, 2 ways of fixed current type, and 4 ways of flexible resistance/current/voltage type, which can precisely detect data of water temperature, oil pressure, fuel level, air compressor venting pressure, and venting temperature etc.

Multiple temperature, pressure, and level sensor curves can be used directly, and custom sensor curve is also available.

Can precisely collect all kinds of parameters of air compressor, which provides high water temperature, low oil pressure, over speed protection, and venting pressure high, venting temperature high protection etc. with complete protection functions.

Speed regulator function can automatically adjust speed to make it steady according to venting pressure of the air compressor.

All outputs are relay outputs.

Parameter setting function allows users to change and set the parameters, and at the same time they are stored in internal EEPROM memory and will not get lost at outage.

Crank disconnect conditions (speed, oil pressure) are optional.  

Power supply range DC (8-35V), which can suits different battery voltage environment.

Event log, real-time clock display functions, which can record cyclically 200 data (including engine speed, water temperature, oil pressure, fuel level, battery voltage, compressor venting pressure, venting temperature, loading status information);

Black box recording function, which can record cyclically 5 events, 50 data between previous 50s and afterward 10s for every event (including engine speed, water temperature, oil pressure, fuel level, battery voltage, compressor venting pressure, venting temperature, loading status information);

Heater, cooler and fuel pump control functions;

Maintenance function; maintenance type can be real time clock, running time or real time clock + running time; maintenance time due action can be set (indication (only for PC software), warning or shutdown alarm);  

All parameters apply digital adjustment, getting rid of common potentiometer's analog regulation method, and improving reliability and stability of the whole device.

Sealing gasket is designed for enclosure with IP65 protection class.

Metal clips are used to fix the controller, and they are especially outstanding under high temperature environment.

Modular design, antiflaming ABS plastic shell, pluggable terminals, built-in mounting, compact structure and easy installation.
