miniature plc ckt. for alarm systems


Thread Starter

bibish arvind

dear sir,
I am at the look out of a plc designed alarm system that should be to the best smallest size possible and also equally economical when
compared with a electrical ckt. consisting of an
MCB, a contactor and a ON delay timer.

Please send me the details of the above mentioned
Ckt. and the programs fed to the PLCs.

Thanking you,

Bibish arvind
