ADCA UNIVERSAL PROCESS CONTROLLERS UC-820 DESCRIPTION The ADCATrol UC-820 is a digital universal controller used in the automation of industrial processes. It is ideally suited for use with our range of instrumentation, electric and pneumatic control valves and other electrical equipment. The controller includes a set of universal type inputs for RTD, thermocouple (TC), logic (binary) and analog inputs. The controller has options for relay, open-collector (OC) and analog outputs using the innovative SMART PID algorithm. MAIN FEATURES Universal measuring input: Resistance thermometer (RTD), thermocouples (TC), 0(4) to 20 mA and 0 to 5/10 V. Set point value: constant, programmed or from the additional analog input. On/off, PID, PID three-step and two-step control (valve control) or PID of heating-cooling type. 2 NO relay alarm outputs and 2 other outputs of choice between relay, OC or analog outputs (0/4 to 20 mA or 0 to 10 V). Binary input control. Soft-start function. 8 types of alarm functions. 24 V DC supply output to power transmitters and others. Signal retransmission. “Gain scheduling” and timer functions. Auto-tuning using the smart PID algorithm. Galvanically isolated inputs and outputs. Password protection. Fully programmable from the front panel. RS-485 Modbus RTU communication. IP rating IP 65.
