Allen-Bradley 800TC-QTH2B Temperature Controller

Allen-Bradley 800TC-QTH2B Temperature Controller is a compact, panel-mount control device from Rockwell Automation designed to regulate process temperatures in industrial environments. The 800TC-QTH2B model belongs to Allen-Bradley’s 800T/800TC temperature-control family, and Rockwell Automation maintains an official product page along with a cutsheet that details installation, wiring, and configuration. This controller is intended for heating and cooling loops where reliable temperature regulation is required in manufacturing, processing, and packaging lines. The official documentation covers the device’s electrical ratings, input/output configurations, mounting dimensions, environmental specifications, and safety considerations, enabling engineers to specify compatibility with common sensors and actuators used in industrial control panels. When selecting a temperature controller, users typically review setpoint range, control algorithm options, output type, and any available diagnostics or status indicators described in the cutsheet and product page to ensure the 800TC-QTH2B meets their process requirements.
