The product You were Looking for was moved Click Here for new Address E-610 LVPZT Amplifier & Position Servo-Controller Modules, OEM Version Open-Loop and Closed-Loop Versions Optional RS-232 Interface For Capacitive, Strain Gauge and LVDT Sensors 14 W Peak Power Runs on Single Stabilized Voltage (12 to 30 VDC) The E-610 is an OEM, stand-alone, amplifier & position servo-control board for low-voltage PZTs. Four versions are available: E-610.00 (open-loop, amplifier only) and the closed-loop versions E-610.S0, E-610.L0 and E-610.C0 (with additional circuitry for position sensing and servo-control). Version E-610.S0 controls strain-gauge-sensor-equipped PZTs, version E-610.L0 controls LVDT-sensor-equipped PZTs and version E-610.C0 controls capacitive-sensor-equipped PZTs. The open-loop version (E-610.00) can be operated in two ways, the closed-loop versions in four ways: I. Open-Loop External Operation (amplifier mode): Output voltage is controlled by an analog signal ranging from -2 to +12 V. Multi-plying by the gain factor of 10, an output voltage range of -20 to +120 V results. If an external offset potentiometer (not included) is connected, it allows for continuous shifting of the input range between -2 V to +12 V and -12 V to +2 V (see link). II. Open-Loop Manual Operation (power supply mode): With 0V input signal, output voltage can be set by an external, DC-offset potentiometer (not included) in the range of 0 to 100 V. III. Closed-Loop (position-control mode) External Operation: Displacement of the PZT is controlled by an analog signal in the range of 0 to +10 V. The controller is calibrated in such a way that 10 V corresponds to maximum nominal displacement and 0 V corresponds to zero displacement. If an external offset potentiometer (not included) is connected, it can be used to add an offset voltage of 0 to 10 V to the input signal. IV. Closed-Loop Manual Operation: With 0 V input signal, displacement of the PZTs can be set by a DC-offset potentiometer (not included) in the range of zero to nominal displacement. Only one unipolar stabilized voltage in the range of 12 to 30 VDC is required to operate the E-610. An integrated DC/DC converter generates the PZT operating voltage and all other voltages used internally. All inputs and outputs are via the male 32-pin rear connector. A matching female 32-pin connector, a LEMO ERA.00.250.CTL PZT operating voltage connector, and a LEMO ERA.0S.304.CLL sensor connector are included to interface with standard PI LVPZTs. Computer Controlled Mode: For computer control, the E-621 controller boards are available (see link for details). E-610 E-610, open-loop frequency response with various PZT loads.
