Model 2430 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 +VS and -VS
voltages. This input may also be used to offset the
output but the voltage difference between this input
and either supply voltage (+VS or
-VS) must be greater
than or equal to 7V.
X, Y & Z (Outputs): Green, Light Brown & Light Blue wires
respectively. These output voltages are proportional
to
acceleration;
they
increase
with
positive
acceleration and decrease with negative acceleration.
At zero acceleration the output is nominally equal to
zero volts with respect to OUTPUT REF.
PERFORMANCE - By Model: V
S=±12 to ±16VDC, TC=25
EC.

Notes: 1. 100g versions and above are tested from -65g to +65g.
2. Operation with V
S below ±12V may result in some performance degradation.
3. Power source must be capable of providing 3 times the operating current at turn-on.
