Watlow The PM LEGACY™ series panel mount controller

The PM LEGACY™ series 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 LEGACY includes one universal input and an option

for up to two outputs and is available in 1/32. and 1/16

DIN panel mount packages. It can be ordered as a PID

process controller or as a dedicated over and under-temperature

limit controller.
