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.

High sampling rate & resolution

High-speed A/D conversion and powerful digital processing capability of 1200 times/sec.
High display resolution of 1/100000 (max).

 
Application software for USB interface

With communication through USB interface, logging, graph, display, setting parameters, and calibration can be done.

High performance filter & Auto filter adjustment

With combination of the low pass filter (0.1 to 300 Hz) which corresponds to various vibration and the moving average filter (OFF, 2 to 512) that is effective for periodic vibration, the automatic searching for optimal value with accuracy and stability can be achieved. (You can manually adjust the settings too).

Compact size

It can be fit into a limited space!
Lightweight & 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 with D/A converter, RS-485 , and USB interface.


Various functions useful for automated weighing systems

■ Basic weighing process control function
Equipped with weighing sequence function to control feeding/discharge gate.

■ Input conversion value display
The output signal level of the connected load cell can be displayed in mV/V for monitor purpose.
Malfunction indicator or faulty sensor can be differentiated easily.

■ 6-digit display
24 bit A/D converter enables 6-digit display

■ Equivalent input calibration
Theoretical calibration can be performed easily by registering the capacity and rated output of load cells.

■ Multipoint calibration (linearization)
Three additional points can be defined in the middle between zero and span for better linearity.Eventhough the scale has poor linearity, it can be corrected to be a highly accurate scale.
