Pyrotech electronicspepl offersmanufactures a micro-controller based multi setpoint controller, model 9dic-990. This which is highly reliable and accepts rtd pt-100, thermocouple, dc ma or dc v inputs. It and has up to 8 set points.. There is common dead band facility for relay outputs. The set points are programmable through feather touch keyboard and there is a visual indication by separate led for each set point. 1 no/nc relay contact with 5 a/230 v ac is available output linear with respect t temperature for rtd and thermocouple inputs. Cold junction compensation for thermocouple input and lead resistance compensation for pt-1900 sensor input are standard. The unit also features fail-safe [relay energised for normal running] operation and memory retention is more than 5 years [no battery required]. The micro controller unit can be used for a variety of application in petroleum, chemical, steel, sugar and other related process in industries.
