A-621L
Load cell converter board
The A-621L is a load cell converter that uses a low-noise instrumentation amplifier IC. It operates on a single 5V power supply with a required current of 25mA. It has a built-in power supply for driving the load cell, allowing direct connection to a 350Ω load cell. The power supply for the load cell provides a voltage of 3.89V ±5%, with a maximum current of 12mA. It is equipped with a trimmer for sensitivity adjustment and a trimmer for 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, and the offset adjustment range is ±0.5V. The dimensions are 55×30×13 mm.
