Barber-Colman AX143 Controller

Barber-Colman AX143 Temperature Controller is a legacy setpoint-temperature controller identified by model AX143 and cataloged within the 2404/CC/VH/XX/XX/XX/XX/XX/XX/XXX/AX143/XXXXXX family. It regulates industrial process temperatures by using a user-setpoint compared against a sensed temperature to drive heating or cooling equipment, a configuration typical of Barber-Colman's 2404-series temperature controllers. The unit's physical dimensions are 4.0 in wide by 3.8 in high by 6.5 in deep, and it weighs about 1 lb 5.3 oz (approximately 0.6 kg); manufacturing is listed as the United Kingdom. This AX143 designation appears across surplus and repair catalogs for Barber-Colman temperature control hardware, reflecting its role in older automation systems used in ovens, furnaces, and other temperature-controlled industrial processes.
