A-820L
Load cell converter
The A-820L is a load cell converter that uses the AD8221AR low-noise instrumentation amplifier IC from Analog Devices. It operates on a single +5V power supply and requires a current of 25mA. It has a built-in power supply for driving load cells and can be directly connected to a 350Ω load cell. It is equipped with trimmers for sensitivity adjustment and offset adjustment, making it easy to calibrate. The rated output is 2V (+2.5V±2V). The sensitivity adjustment range is 0.5mV/ to 2.2mV/V. The offset adjustment range is +2.5V±0.5V. It uses a one-touch terminal block ML-950-4 (Sato Parts) for input and output. The external dimensions are 70×40×16.
