detailed description

overview

Wallace & Tiernan ® The SFC PC process controller is specifically designed to automatically control disinfection, dechlorination, and chemical dosing in water treatment or industrial processes. SFC PC systems are commonly used as set point controllers to achieve precise control of gas dosing equipment and chemical metering pumps. It adopts an intuitive approach that is easy to operate, set up, and calibratemenuThe navigation system makes complex control functions simple and easy to implement.

Typical applications

·Drinking water treatment
·Wastewater treatment
·Cooling circulating water
·Industrial and Process Water Treatment
·Swimming Pool

characteristic

SFC PC devices can be installed separately on walls, as equipment, or as panels inside control cabinets. The SFC PC process controller has four control modes to choose from:
·Composite loop - using "fuzzy logic" automatic tuning control technology, the controller responds quickly based on the minimum deviation of the set point.
·Single feedback or direct margin control - ideal mode for closed-loop systems
·Feedforward
·Traffic ratio

advantage

·There are four on-site selectable control modes, including process optimization and adaptive control
·By combining with appropriate measuring units, an independent analyzer/controller device can be constructed
·Visual graphical display of all parameters and process variables
·Intuitive menu navigation for easy operation
·Up to 16 user-defined alarm relays for different situations
·Input and output isolated current signals
