RS485 mini signal conditioner board
1.
PRODUCT DESCRIPTION
The RS-485 signal conditioner utilizes Fredericks single and dual axis electrolytic tilt sensors. The
signal conditioner provides the necessary excitation to the sensor and signal conditioning of the
output to communicate over a RS485 interface.
Standard industrial RS-485 interface enables long transmission distances and possibility to connect
multiple modules, with individual addresses, to the same bus. In addition to tilt angle, temperature
information is also available from the module that can be used for temperature compensation of
the sensor.
