JB4-HX711

Description

The JB4-HX711 is an amplifier for load cells and strain gauges. It combines the functionality of the HX711C and the JB4 to simplify weighing installations. Multiple load cell outputs are summed and it uses the HX711 Integrated Circuit (IC) to convert the mV/V output signals from load cells into amplified digital value that can be read by a microcontroller or PLC system.
