INTERCONNECTION DIAGRAM
NOTE:
4 wire LVDT connection requires access to the center connection of both secondaries. One wire from each of the secondaries and the primary will be tied together and attached to COMMON. The remaining three leads will be connected as shown in the connection diagram.

VOLTAGE AND 4-20mA OUTPUT VERSIONS
The equivalent models for voltage and 4-20mA output are shown in the table below, along with frequency, phase angle and frequency response for each. All of these modules are physically identical and require the same dual bipolar voltage supply. The output pins 5 and 1 are used for the current output.
| VDC MODEL | 4-20 mA MODEL | FREQUENCY KHz ±10% | LVDT PHASE ANGLE | FREQUENCY RESPONSE, Hz |
| 1000-0011 | 1000-0021 | 3 | ALL | > 500 |
| 1000-0012 | 1000-0022 | 7 | > 10 Degrees | > 1000 |
| 1000-0014 | 1000-0024 | 7 | > 1000 |
NOTE: Current Loop impedance must be between 5 and 400Ω for linear operation
