Watlow 97B0-DAAU-00RG Temperature Limit Controller

The Watlow 97B0-DAAU-00RG Temperature Limit Controller is a microprocessor-based safety limit controller that provides independent over-temperature protection and automatic process shutdown for industrial heating systems. It operates from a 24 VAC/VDC supply, part of Watlow’s Series 97, and features a relay output, RS485 serial interface, and supports RTD and thermocouple sensor inputs, all displayed on a digital LED process display and housed in a panel-mount enclosure. Commonly installed in industrial ovens, furnaces, heat-treatment equipment, plastic-processing machinery, and environmental chambers, it is designed for continuous-duty operation and suitable for OEM equipment and replacement installations. Common replacements include Watlow 97B0-DAAU-00RR, 97B0-DAAU-00GR, and 97B0-DAAU-00GG.
