LDM-1000 LVDT/RVDT Signal Conditioning Module SPECIFICATIONS  10 to 30VDC operation  Standard DIN rail form factor  4 to 20mA and VDC outputs  Zero, span and phase adjustable  2.5, 5 and 10kHz excitation frequencies  Low noise, 3-pole Butterworth filter  Master/slave capability  Compatible with 4, 5 & 6-wire LVDTs/RVDTs  Works with very low input impedance LVDTs and RVDTs The LDM-1000 is an extremely versatile and popular LVDT/RVDT signal conditioning module and the perfect choice for industrial applications requiring the DIN standard rail mount. The LDM-1000 provides everything you will need for accurately FEATURES interfacing an AC operated Linear or Rotary Variable  Standard DIN rail form factor Differential Transformer to your industrial position control  Voltage and current output signals system.  Phase correction  Status LED’s for power and loop The LDM-1000 was designed with maximum sensor/system compatibility in mind. A wide range of gains, excitation voltages integrity and frequencies ensure compatibility with virtually all LVDT and  Multiple LVDT master/slave RVDT type transducers. A full-wave synchronous demodulator capability eliminates quadrature and harmonics to maximize external noise rejection. APPLICATIONS The LDM-1000 also provides several different input/output  Gas and steam turbine control options to accommodate varying PLC and analog I/O systems requirements:  Process control systems  Single-ended voltage outputs with the use of 100% zero suppression to maximize the sensor stroke  Reeler/dereeler control systems utilization while simplifying programming (no need to  Automotive test track deal with sign) instrumentation  Bipolar voltage output to maximize A/D bit usage with  Paper head box control most PLC analog input modules, for applications requiring high resolution  4-20mA current output for applications requiring long signal runs or where noise immunity may be an issue. The 4-20mA loop is driven by an internal power supply, provided by the LDM-1000. Finally, the frequency response is internally selectable and so is the master/slave function which allows synchronization of multiple LDM-1000 modules to prevent beat frequencies and cross talk between transducers.
