CCT-05
Signal converter for frequency signals. Internal jumper selection for 5 different ranges of measure, ranging from 0/40 Hz up
to 0/40 Khz. Accepts PNP, NPN, Namur and sinusoidal signal types. Provides two types of excitation voltages for transduc
-
ers, 24 Vdc for PNP and NPN types, and 8,2 Vdc for NAMUR types.
Configure the desired frequency input range and sensor type by selecting the appropriate jumpers on «MP» module, as
shown on the tables below:

PT1 - Fine Gain Adjustment. (Additional P2 potentiom

eter on input module ME).
PT2 - Trigger Adjustment. Is the voltage level at which the
input signal is recognized to be as logic ‘1’ or logic ‘0’. It
can be set empirically operating on potentiometer PT2.
