RC47 is a “single loop” digital microprocessor-based controller, with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual action (direct and reverse) control and with AUTO-TUNING FAST function, SELF-TUNING function and automatic calculation of the FUZZY OVERSHOOT CONTROL parameter for PID control. The PID control has a particular algorithm with TWO DEGREES OF FREEDOM that optimises the instrument’s features independently in the event of process disturbance and Set Point variations. The process value is visualized on 4 red display, the Set value is visualized on 4 green display while the outputs state is indicated by 4 led.
The RC47 instrument provides for the storage of 4 Set Points and can have up to 3 outputs: relay type or can drive solid state relays type (SSR). The input is programmable and accepts temperature probes (Thermocouples J,K,R,S,T, Thermo-resistances PT100, Thermistors PTC and NTC;) and normalized analogue signals (0/4..20 mA, 0/1..5 V, 0/2..10 V, 0..50/60 mV, 12..60 mV).
Other important available functions are: Loop-Break Alarm function, reaching of the Set Point at controlled speed, ramp and dwell function, Soft-Start function, parameters protection on different levels. If it is powered from Vac line, to avoid breakdown the instrument must be galvanically separated from other components through the use of a transformer.
