data sheet the fc series ratio setter is used to set ratio for ratio control, and its set point signal is transmitted to a controller. this instrument uses a solid state indicator and a push- button operation system to provide reliable monitoring and operating functions. it also accepts a thermocouple, a resistance bulb and a 4 to 20ma dc input optionally. 1. high reliability this instrument is designed with few mechanical parts. it is mainly composed of electronic parts such as a solid state indicator which was formerly consisted of mechani- cal parts. 2. international standards this instrument is compact in size, conforming to inter- national standards iec. it operates on 24v dc power to deliver 1 to 5v dc signals as recommended by iec stand- ards. 100 and 200v ac power are also available for conven- ience of operation. 3. front panel operation process values and set points can be read accurately with digital indications on panel front. various parameter settings and setting operations are also possible from the front panel of the instrument. process value input (pv) square-root extraction linearize filter pv sv so alm kpv sv l r external set point input (cas or pi) (1 to 5v dc, pulse width, or pulse number) local mode output (ls) remote reque s (r-req) set point output (so) squared set point output (so2) high alarm output (h) low alarm output (l) ratio output signal (sv) compensated process value signal (kpv) remote acknowledge signal (r-ack) limiter r b1 b2 b3 h l limiter h l so 2 so = r x (sv+b 3 ) x (pv? 1 ) + b 2 png1 fc series ratio setter features functional diagram date EDS11-106E jul. 1, 1994
