The Watlow® EZ-ZONE® PM Express panel mount controller is an industry leading PID controller that allows optimal
performance utilizing simple control and menu functionality without complex features. It is ideally suited for basic applications and usage levels.

The EZ-ZONE PM Express is the next generation controller to follow the legacy of Watlow’s SERIES 93, SERIES 935 and SERIES SD controllers that offer easy-to-use features to perform many basic applications.
The EZ-ZONE PM Express includes one universal input and an option for up to two outputs and is available in 1/32, 1/16, 1/8 and 1/4 DIN panel mount packages. It can be ordered as a PID process controller or as a dedicated over and under-temperature limit controller.

The EZ-ZONE PM Express is a valuable addition to the EZ-ZONE PM controller family which also includes the EZ-ZONE PM integrated controller and the EZ-ZONE PM standard version.
