KOBASTAR INDUSTRIAL WEIGHING SYSTEMS

Features:

The AC660 is a weighing indicator designed for overload control applications. It features a 48 MHz 32-bit ARM CPU, a 5-digit red LED display, a 24-bit Σ–Δ ADC with an internal resolution of 1/1,000,000 and a high sampling frequency of 1280 Hz.

It uses a digital filtering algorithm for precise weighing.

The device has 1 normally open (NO) digital switch input, 2 SPDT relay outputs (DO) supporting AC 250 V / DC 24 V (1 A), and 1 analog output (AO) with 0.01% full-scale (FS) accuracy, configurable as 4–20 mA, 0–20 mA. Its adjustable baud rate and Modbus RTU support enable easy integration into industrial communication systems.

Applications:

Crane overload control applications, force and weight control applications
