7EF and 7HF Controllers

The 7EF and 7HF Controllers series is a family of 1/8 DIN digital temperature controllers, primarily manufactured by Barber-Colman with related units also carrying Cincinnati Milacron and Ero Electronic part numbers. The 7EF models are vertical-mount units, while the 7HF models are horizontal-mount, giving panel builders and equipment integrators flexible mounting options for the same class of control.

These controllers are designed for industrial process control, accepting thermocouple inputs and providing programmable outputs for temperature regulation and over/under temperature alarm monitoring. They are commonly used in temperature-critical applications such as paper processing and plastics manufacturing.

All products in this series share the 1/8 DIN horizontal digital temperature control base, making it a consistent family suited to equipment relying on Barber-Colman temperature control hardware.
