The Pc 900 is a v ers atile, high s tability tem perature or proc es s c ontroller, with s elf-tuning, in 1/4 and 1/8 DIN s iz es . It has

a m odular hardware c ons truc tion with the option of two c ontrol outputs , two alarm relay s and a c om m unic ations module.Two digital input are inc luded as s tandard. The hardware is c onfigurable for heating, cooling or alarm .

Precise control An adv anc ed P ID c on tr ol algorithm giv es s table s traight-line c ontrol of the proc es s. A on-s hot tuner is

prov ided to set up the initial P ID v al ue s and t o c al cu la te the ov ers hoot inhibition param eters. O n e l ec t ri c al l yheated loads, power feedbac k is us ed t o s ta bi li se the output power and henc e the c ontrolled tem peratureagains t s upply v oltage fluc tuations.

7.2 Operation Keys

There are eight keys on the controller panel.
