2.1. Overview
The type FAD-40 A/D Converter Series consists of powerful and economic state-of-the-art instruments for static
and dynamic weighing applications plus force and torque measurements including digital I/O control.
Each instrument of the series converts the analogue low level signal from a load cell or a strain gauge sensor to
a digital high-resolution and high-accuracy signal and transmits the digital data to an external PLC or PC
system. As a special feature the instruments can switch between unipolar and bipolar input range without
affecting the external resolution. Digital I/O ports give further possibilities to extend the bus system with I/O
control in the cabinet and fast response setpoint output from the weighing instrument.
The type FAD-40 A/D Converter Series comprises various instruments for different industrial bus systems:
