TM Model 2264
Analog Accelerometer Module
SIGNAL DESCRIPTIONS (28 gauge wires + shield)
Power: +Exc (Red) and -Exc (Black): +Exc (+3 to +11 VDC)
and -Exc (-3 to -11 VDC).
+Out (Green) and -Out (White): +Out minus -Out voltage is
proportional to acceleration; +Out voltage increases and -Out
decreases with positive acceleration. At zero acceleration both
outputs are nominally equal to mid-way between the +Exc and
the -Exc values. The device experiences positive (+1g)
acceleration with its lid (part number) 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)
