capaNCDT 6200
2.2.3 Controller
The capaNCDT 6200 Multi-channel measuring system consists of a basic module DT62xx and one up to four
demodulator modules DL62xx, according to requirements. The components are stored in aluminum hous-
ings.

Basic module DT62xx
The basic module consists of the units voltage conditioning, oscillator and digital unit.
The voltage conditioning generates all required internal voltages from the supply voltage, both for the basic
module as well as the connected demodulator modules. The oscillator supplies the demodulator modules
with constant frequency and amplitude-stable alternating current. The frequency is 31 kHz. The digital unit
controls the A/D converter of the demodulator modules and measures the actual measuring values. The mea-
suring values can be read out via the Ethernet interface in digital form, see 6.
