Universal process controller UC-820

DESCRIPTION

The 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 equipments.

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…20 mA and 0…5/10 V.
• Binary input control.
• 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 outputs and 2 other outputs of choice between relay, OC or analog outputs (0/4…20 mA or 0…10 V).
