Model 2220 Analog Accelerometer Module
SIGNAL DESCRIPTIONS
Vs and GND (Power): Red and Black wires respectively. Power
(+9 to +32 Volts DC) and ground.
AOP and AON (Output): Green and White wires respectively.
Analog output voltages proportional to acceleration; AOP voltage
increases (AON decreases) with positive acceleration. At zero
acceleration both outputs are nominally equal to 2.5 volts. The
device experiences positive (+1g) acceleration with its lid facing
up in the Earth’s gravitational field. Either output can be used
individually or the two outputs can be used differentially. (See
output response plot below)
