FC400-DAC

 

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.

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

 

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

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.

 

■ 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.
