Features:

The AC680 is a weighing indicator designed for overload control applications. It features a 48 MHz 32-bit ARM CPU and a 6+8 red LED digital display for English characters and numbers. Its 24-bit Σ–Δ ADC provides an internal resolution of 1/1,000,000 and a high sampling frequency of 400 Hz.

It uses a digital filtering algorithm for precise weighing. Up to four 350 Ω load cells can be connected. The device has 6 digital inputs and 5 normally open relay contact outputs, comprising 4 setpoint outputs and 1 no-load zero-range output.

Applications:

Crane overload control applications, force and weight control applications
