Product description
DPBIT34 is a PT100 amplifier component for interfacing a standard PT100
temperature sensor to the Bitlink 2-wire
bus system. The component has a 12 bit
A/D converter and interfaces to sensors
following the IEC751 standard. DPBIT34
uses a 2-wire connection from sensor
to amplifier, with a maximum allowable
cable length of 2m (6 ft).
The Bitlink bus and the sensor are not
electrically isolated. The point address is
selectable from 0 to 255.
