FC500

DIN-rail mount weighing indicator with RS-485 interface

Product outline

FC500 is a weighing indicator equipped as standard with RS-485 interface. It is ideal for a variety of weighing applications like hopper scales, bagging machines, and level meters. Measured data and results can be collected using RS-485 interface.

Lightweight and compact body to fit into limited space in a control panel

Light weight & compact body for 35 mm DIN rail mount Dimensions: 65(W)×94(H)×108(D) mm (Not including projections) Weight: Approx. 370 g

Various interfaces

RS-485、SI/F、USB interfaces is equipped as a standard feature

High sampling rate & resolution

High-Speed A/D conversion and powerful digital processing capability of 1200 times/sec.(Convertible to 300 times/sec.). High display resolution of 1/100000 (max).

Application software for USB interface(Free software)

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

Various functions useful for automated weighing systems

■ Equipped with data memory function Latest 100 data of calibration value and error information with clock time are recorded and can be checked via USB interface.

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

■ Memory for 32 weight settings 32 different weight settings can be saved in the memory and selected through I/O or interface. Batch weighing can be performed easily.

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

■ 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.

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