Watlow 985A-3CD0-0000 PID Temperature Controller

The Watlow 985A-3CD0-0000 PID Temperature Controller is a microprocessor-based PID process controller engineered for precise temperature regulation and monitoring in industrial heating and automation systems. This panel-mount unit from the 985 series features a dual digital LED display for clear visibility of both the current process value and the setpoint, and it supports both PID and On/Off control modes to match your control strategy. It accepts thermocouple, RTD, and other process inputs, while its outputs provide configurable control and alarm channels (configuration dependent) to suit a range of equipment architectures. Built for continuous-duty industrial operation, it is suitable for OEM equipment and replacement installations across environments such as ovens, furnaces, extrusion lines, plastic injection molding machines, packaging lines, environmental chambers, heat-treatment systems, laboratory ovens, semiconductor manufacturing systems, and automated production lines. Common replacements include Watlow 985A-3CD0-00RG, 985A-3CD0-00RR, and 985A-3CD0-00GR.
