THE HD 588 MODULAR SIGNAL CONVERTER WITH 3-WAY GALVANIC
SEPARATION FOR THE PROCESSING OF ANALOGUE SIGNALS
0÷20mA
4÷20mA
0÷10V
Built inside a 2-module DIN box for 35 mm asymmetric guide, the converter
offers, as well as a conversion of analogue signals between input and output, a
complete galvanic separation among input, output and power supply. The 3-way
circuital configuration ensures a definite decoupling of the sensor circuit from the
external control circuit, preventing reciprocal influences in the presence of various
measuring circuits.
The HD 588 converter module is made up of the following sections:
- Universal input stage with signal conversion from voltage into frequency.
- Universal output stage with signal conversion from frequency into voltage.
- Power supply stage.
Configuration can be modified through jumper connections, an important feature
being the possibility of modifying the type of input and output without having to
calibrate the converter again. By simple operations the HD 588 converter allows
up to 9 different combinations between input and output.
