data sheet pnc1 compact controller s (fixed function type) is a compact single-loop controller using a microprocessor. it accepts uniform signals, and signals from a thermo- couple and resistance bulbs as input, and includes sufficient control and computation functions which permit composition of a flexible system for pid control, square-root extraction, non-linear control, etc. 1. pid auto turing function optimum pid parameter can be obtained for processing. 2. high reliability led's (red and green) are used for the bar graph indicator and for parameter indication (red). a non-volatile memory retains the control and computation parameters even if power should be interrupted. 3. all operations are performed from the front of the panel operations such as parameter setting, auto/manual changeover are performed from the front of the panel. 4. transmission function incorporation of transmission function permits setting of concentrated monitoring data at the host system. fc series compact controller s (step output type) features functional diagram personal computer to other controllers bar graph indicator communication terminal linearize a.m 4 to 20ma, thermocouple/ resistance bulb conversion external input terminal d/a converter opening/resistance conversion valve position input (w 0 ) process value input (pv) external set point input (cas) pulse input (pi) manual mode command (smv) pv tracking (di1) remote acknowledge signal (di3) : option a/d converter internal input terminal filter r r m mode non-linear pulse width conversion m mode r mode fault l or scc mode square-root extraction p i d sh sl h mv l m r.a alarm flt lamp h lamp l lamp control output (pulse width) (po) valve position output (voltage) (ao1) compensated pv signal output (kpv) set point transmit signal output (sv) manual mode output (m) local mode output (do1) remote request (r-req) fault output (flt) high alarm output (h) low alarm output (l) external output terminal date EDS11-101E jan. 27, 1999
