Watlow 988A-10BB-AAEH PID Temperature Controller

The Watlow 988A-10BB-AAEH Temperature Controller is a microprocessor-based PID controller in the Watlow 988 Series that delivers precise heating and cooling regulation for industrial processes. Housed in a 1/8 DIN panel-mount enclosure with a digital front-panel display, it supports auto-tuning and configurable input/output options that vary by model configuration to fit OEM equipment and automation projects. This controller is commonly installed in ovens, furnaces, packaging machinery, plastics processing equipment, and laboratory systems, and it supports temperature and process control across applications such as heat treatment, food processing, semiconductor manufacturing, environmental chambers, and pharmaceutical production. Maintenance teams, OEMs, and system integrators use the 988A-10BB-AAEH for replacements, retrofits, and control-panel upgrades, with common replacements including Watlow 988L-10CE-AARG Temperature Controller and Watlow PM6C2FA-BAEAPWP PM PLUS Temperature Controller.
