It combines three orthogonally mounted model 1221L accelerometers in a rugged case for measuring accelerations in commercial/industrial environments. This module is tailored for zero to medium frequency instrumentation applications. Its anodized aluminum case is epoxy sealed and is easily mounted via two #8 (or M4) screws. On-board voltage regulation and an internal voltage reference eliminate the need for precision power supplies. It is relatively insensitive to temperature changes and gradients. An optional initial calibration sheet (2460-CAL) and periodic calibration checking are also available. OPERATION 4 AO N P AO 3 2 1 0 -Full Scale 0 + Full Scale ACCELERATION SIGNALS APPLICATIONS • • • • • • • 5 OUTPUT VOLTAGE The Model 2460 produces three differential analog output voltage pairs (AON & AOP), which vary with acceleration as shown in the figure (at right). The signal outputs are fully differential about a common mode voltage of approximately 2.5 volts. The output scale factor is independent from the supply voltage of +8 to +32 volts. At zero acceleration the output differential voltage is nominally 0 volts DC; at ±full scale acceleration the output is ±4 volts DC respectively. The axis directions are marked on the case with positive acceleration defined as acceleration in the direction of the axis arrow.

Universal Analog Accelerometer Module Model 2460 CABLE SPECIFICATION & LENGTH CONSIDERATIONS The cable consists of seven 28 AWG (7x36) and one 26 AWG (7x34) tin-plated copper wires. The seven smaller 28 AWG wires are covered by 5.5 mils of Teflon FEP insulation. The larger single 26 AWG wire is covered by 8.5 mils of black Teflon FEP insulation. The seven smaller gauge wires surround the single larger gauge (black) wire. The wire bundle is surrounded by a braided shield and covered by a 10 mil thick Teflon FEP jacket with a nominal outer diameter of 0.136”. Cable lengths of up to 15 meters (50...
