Air/fuel ratio controller AF120

The AF120 Air/Fuel Ratio Controller provides cost-effective emissions control for gaseous fueled engines used in demanding industrial applications. The module is designed to accurately control the air/fuel ratio of stoichiometric engines fitted with a three way catalytic converter, and lean burn engines with or without a Catalytic Convertor. The AF120 Air/Fuel Ratio Controller can be used within a variety of control systems. In the carburettor bypass configuration the Gill AF120 fuel valve can be utilised. Alternatively the module can be used to control fuel pressure regulator systems and systems requiring turbo waste gate control. Please scroll down for all our other compatible products. One module can be used for rich-burn, lean-burn or 4-20 mA operation Fast start up due to heating of UEGO sensor. Programmable via easy to use Windows based software Controls Lambda value with dynamic, single setpoint technology Adjustable valve start-up position and warm-up time. Load mapping feature included The 4-20 mA output can drive pneumatic control valves on engines equipped with turbo waste gate TECHNICAL Supply Voltage: 12-24 VDC Operating Temperature: -40ºC to +90ºC Environmental Protection: IP67 Inputs: Throttle position or MAP sensor for load mapping. Wideband UEGO sensor for exhaust oxygen measurements. Additional sensor inputs for more rigorous applications. Outputs: AF120 Fuel Valve or 4-20mA controlled valve Communications: RS232 for programming via Windows® based GUI
