Series 988 Process Controllers
The Series 988 Process Controllers from Watlow are 1/8 DIN digital temperature and process controllers built for precise thermal management in industrial applications. Available in 988A and 988B base configurations, these controllers accept thermocouple or RTD inputs and provide configurable outputs for heating or cooling processes.
The series spans a wide range of input, output, and communication configurations, including single and dual input models, dual DC and other output types, and units equipped with RS-422/485 serial communication for integration into networked control systems.
Typical Applications
Controllers in this series are commonly used in:
- Paper processing
- Plastics processing and extrusion
- Packaging machinery
- Food production lines
- Heat treatment furnaces and other manufacturing equipment
