They are signal amplifiers that convert a signal from a specific sensor to a normalized analog output mA or Vdc.

The teams are ready for installation on DIN rail 35 mm. The power can be 230 Va, or low voltage 24 Vac / dc. There are also models that are fed by the output loop 4 to 20 mA.

We have different models depending on the input:

Input mAd or Vdc. Signal conversion from mA or Vdc to Vdc or mAdc. It has normalised inputs 0/1 mAdc, 0/20 mAdc, 4-20 mAdc, 0/1 Vdc, 0/5 Vdc, 1/5 Vdc, 0/10 Vdc. The most common devices belong to the series LEXITRON C3 with 220 Vac supply and the excitation version 24 Vdc/24mA for transmitters.

RTDs input. The model LEXITRON C3N has an input PT100 with fixed range and output 4-20 mA or 0 to 10 Vdc. Compensation of the cable length through the third wire.

Thermocouples input. For J and K thermocouples, the models LEXITRON C3J and C3K converts the output to 0-10 Vdc and 4-20mA.

We also have available the LEXITRON model TRBI, programmable by PC with thermocouple or RTD input and supply by loop of the 4-20 mA output. It has a perfect linearization software.

 

Entrada puente extensiométrico. Converters C3B with mVdc input and excitation of 5Vdc or 10 Vdc for the bridges are ideal for amplification of load cells. They have analogic settings of 0 and sensibility. Also, the series ISI DMS from IMTRON are specially indicated for testing with force sensors. It has a response of 5 KHz in order to amplify the measurements in real time.

Electric signal input. Specific signal converter for AC signals and measurement calculations of: Voltage Vac, direct current Aac (up to 5 A) or or through current transformer, frequency, cosine Fi, active power, reactive power, etc.

Entrada potenciómetro. The model with an excitation of 10 Vdc for potenciómetros of 2 Kohm to 40 KOhm converts the element signal to an analog output.

Pulse input. Usually we need to measure the frequency to determine an instantaneous flow rate or velocity from the input pulses. To do this, we apply configurable converters both in input type (PNP, NPN, NAMUR, TTL, etc.) and frequency range.

Less often we have a model for counter function generating an analog output based on the accumulation of input pulses (e.g. from a rain meter signal).

Electrochemical sensors input. Specific converters for PH sensors, conductivity, REDOX, etc.
