Model 2440 Triaxial Analog Accelerometer Module
SIGNAL DESCRIPTIONS
+VS (Power): Reddish brown wire. Apply +11 to +16 Volts
DC with respect to OUTPUT REF.
-VS
(Power): Black wire. Apply -11 to -16 Volts DC with
respect to OUTPUT REF.
OUTPUT REF (Input): White wire. The X, Y & Z outputs
are referenced to this potential. This input is usually
tied to a potential halfway between the +V
S
and -V
voltages. This input may also be used to offset the
S
output but the voltage difference between this input
or -VS) must be greater
and either supply voltage (+V
than or equal to 11V.
S
X, Y & Z (Outputs): Green, Light Brown & Light Blue wires
respectively. These output voltages are proportional
to acceleration; they increase with positive
accelerationanddecreasewithnegativeacceleration.
At zero acceleration the output is nominally equal to
zero volts with respect to OUTPUT REF.
PERFORMANCE - By Model: VS= 12 to 16VDC, TC=25EC.
