EZ-ZONE PM Temperature Controller

The EZ-ZONE PM series from Watlow is a family of panel-mount temperature and process controllers designed for precise thermal regulation in industrial applications. These controllers monitor temperature inputs via thermocouple or RTD sensors and drive heating or cooling outputs to maintain programmed setpoints using PID control algorithms.

The series spans multiple panel form factors, including 1/32, 1/16, 1/8, and 1/4 DIN, to suit installations ranging from compact, space-constrained panels to larger control cabinets. Configurations vary across models, with options such as relay, switched DC, and solid-state relay outputs, front-panel keypad programming, alarm functions, and limit control variants.

Common Applications

• Plastics processing machinery
• Packaging equipment
• Food processing and production ovens
• Semiconductor manufacturing tools
• Laboratory ovens and general manufacturing equipment

Products in this series appear under Watlow PM part number prefixes such as PM3, PM4, PM6, and PM8, with alphanumeric suffixes indicating specific input, output, and feature configurations.
