we a microcontrooler based bagging unit of obsolete design. we wish to replace with siemens make PLC(s7 200) for weighing sugar. the existing loadcell range is 14 mv for 0 kg and 28 mv for 100 kg.please reply
you will need a converter for the loadcell to make it a normal plc signal. Is it not somewhere hidden in the machine?
and you will need a controller of any type to see this analog signal and to stop the valve. Or use a complete new PLC for it. however i think siemns is too expensive for this try a small one like plc micro or a wago if needed more assisance just send mail to me. [email protected]
