Watlow 96B0-FDDA-00RR Temperature Controller

Watlow 96B0-FDDA-00RR Temperature Controller is a microprocessor-based PID controller designed for precise temperature regulation and process control in industrial heating systems. Operating on 24-28 VAC/VDC and featuring relay outputs, it provides dependable control of heating and cooling devices in applications such as industrial ovens, furnaces, plastic injection molding machines, packaging equipment, and environmental test chambers. The unit uses a 1/16 DIN panel-mount form factor with a dual digital LED display for clear readouts and supports input from thermocouples, RTDs, and process sensors. It offers PID and On/Off control modes, is part of Watlow's Series 96, and is intended for continuous-duty industrial operation. This controller is commonly used by maintenance teams, OEMs, and system integrators for equipment replacement, control panel retrofits, preventive maintenance, and upgrading automation systems in heat treatment equipment, extrusion systems, food processing machinery, laboratory ovens, semiconductor manufacturing equipment, environmental chambers, and automated production lines. Common replacements include Watlow 96B0-FDDA-00RG, 96B0-FDDA-00GR, and 96B0-FDDA-00GG.
