Watlow 97A0-DDDA-00AC PID Temperature Controller

The Watlow 97A0-DDDA-00AC Temperature Controller is a microprocessor-based PID controller designed for precise temperature regulation in industrial processes and high-voltage equipment. Operating from 100-240 VAC, 60 Hz, it features a digital LED process display and a panel-mount form factor, with input options for thermocouples, RTDs, and other process signals, and supports PID and On/Off control modes. Output configuration includes control and alarm outputs (configuration dependent), and the unit is built for continuous-duty operation in OEM equipment and replacement installations used by system integrators. It is commonly used in ovens, furnaces, extrusion systems, plastic injection molding machines, packaging equipment, environmental test chambers, and other automated lines; common replacements include Watlow 97A0-DDDA-00RG, -00RR, and -00GR.
