Series 942 Temperature Control

The Series 942 Temperature Control family from Watlow consists of 1/4 DIN panel-mount temperature controllers used to monitor and regulate process temperature in industrial equipment. All units in this series share the 1/4 DIN form factor and provide closed-loop temperature control.

The series includes standard temperature controllers as well as RTD-input models and ramping controllers with dual and auxiliary outputs. Several variants offer RS-422 serial communications for integration with supervisory or networked control systems.

Common Configurations

• Standard 1/4 DIN temperature controllers
• RTD-input temperature controllers
• Ramping controllers with dual and auxiliary outputs
• Models with RS-422 communications

Configuration differences are reflected in the Watlow part numbers, which specify input type, output options, and communication features across the range.
