CTFP_U50 – FREQUENCY/VOLTAGE PRECISION CONVERTER

DESCRIPTION
Transmission and conversion signals problems must be
handled effectively. The accurate voltage-to-frequency
converter CTFP makes this possible with a very high precision
level, a low temperature drift and a high galvanic isolation. The
CTFP provides:
-an amplified frequency output for long distance transmission,
-an impulse output which can be used for counting, and
-an optional 0-20mA or 4-20mA analog output.
