To complete your displacement measurement system Magtrol offers
the CST 113 Signal Converter, designed specifically for transducers
delivering a signal of 4 to 20 mA. Either a voltage-based
signal (I/U conversion) or a current-based signal (I/I) can
be chosen as the converter output, along with signal inversion
if required. A large variety of offset and gain values can
be selected, matching all sorts of specific applications.
The use of micro switches (DIP switches) and potentiometers
enable easy on-site adjustments and the independent settings
make it possible to calibrate the CST 113 in one displacement,
from the minimal to the maximum position of the jack.
A "transmission OK" output enables the electrical connection
between the DI transducer and the CST 113 converter to be
checked, thus allowing the system to be used in applications
where safety is important. This operation is simply carried
out by measuring the current coming from the DI transducer.
An anomaly is indicated by the opening of the output transistor.
The CST 113 power supply input features a galvanic separation
to electrically isolate the power supply ground from the measuring
chain ground. The CST 113 circuitry is available with either
a plastic housing, for mounting on a DIN rail, or housed in
aluminum IP 65.
Features
- Wide number of possibilities to select functions
(polarity) and signal ranges (offset and gain)
- Fast calibration in one displacement, with independent
settings
- Transducer supply current up to 80 mA
- Easy to adjust on site: DIP switches and potentiometers
- Plastic or aluminum housing
