PART 3 – KDM-8206 OUTPUTS
The KDM-8206 Measuring Channel has a variety of analog outputs. Standard outputs are:
 Vout (single ended voltage)
 Iout (4-20 mA current).
Optional outputs are:
 Low voltage (0-1, 0-2)
 Differential
(balanced) voltage
 Demodulator
output
 Reverse current (20-4 mA)
Modifications to the Measuring Module and/or Rack may be required for the optional outputs.
Single ended voltage calibration is provided unless otherwise specified.
Voltage outputs are accessed:
Between pins A/C 14 and A/C 16 on the Euro connector
On the rear panel BNC coaxial connector, if installed in a rack
Current output is accessed:
Between pins A20 and A22 on the Euro connector
On the rear panel two position terminal block, if installed in a rack
3.1 Analog Voltage Output:
Unless otherwise specified, the Measuring Channel will be factory calibrated for 0-10 VDC over
the full measuring range of the sensor. Other typical outputs are 0-5, ±5 VDC, and ±10 VDC.
The KDM-8206 output may also be adjusted to provide a specific sensitivity, such as 1 V/mm.
The Measuring Channel in a standard configuration can be adjusted for output ranges of 0-3 VDC
and greater. Lower ranges are available on request and require modification of the Measuring
Channel PCB.
3.2 4-20 mA Current Output:
For industrial applications or long output cable lengths, a 4–20 mA current output may be used. The
loop is powered by the KDM-8206. The current output is designed for a typical 250 ohm load.
However, the current output can provide a precise output into a load from 0 (zero) to 1,000 (1K)
ohms.
3.3 Demodulator Output:
Demodulator output is available between pin A24 and ground (pins A/C10 and A/C26) on the Euro
connector. It is also available at the test points on the front panel. This is the output from the
Synchronous Demodulator before any signal conditioning or linearization. It operates inversely to the
normal output voltage with highest output at the shortest distance.

Demodulator output is typically used for trouble-shooting purposes. It can also be used for special
applications when linearized output may be saturated under certain operating conditions.
