Product outline

FC400-DAC is a compact weighing Indicator with D/A converter.
It is suitable for many weighing applications such as hopper scale, packing scale, weight level meter, etc….
Either voltage or current output, corresponding to the indicated value, is available.

It can be fit into a limited space!

Light weight & compact body for 35 mm DIN rail mount.
External dimension: 34(W) × 88(H) × 91(D) mm (Not including projections)
Weight: Approx. 210 g

Various interface

Equipped as standard with D/A converter, RS-485 , and USB interface.

High-speed sampling & high resolution

High-speed A/D conversion rate at 1200 times/sec.
& high display resolution capability of 1/100000.

The high-speed A/D converter enables the faster and more accurate weighing.

Various features

■ High-performance filter
　With the powerful filter against noise, high-speed an high-accuracy weighing can be achieved.

■ Auto filter adjustment
　The filter is automatically adjusted to reduce the noise when the auto adjustment key is pressed.

■ Equivalent input calibration
　Theoretical calibration can be performed easily by registering the capacity and rated output of the load cell(s).

■ Multipoint calibration (linearization)
　Three additional points can be defined in the middle between zero and span to improve the linearity.

■ Input conversion value display
　The output signal level of the connected load cell can be displayed in mV/V/ for monitor purpose.

■ Basic weighing process control function
　Sequential control can be performed without external devices like PLC.
