EZ-ZONE PM Controllers

Take the Pain Out of Solving Your Thermal Loop Requirements

Watlow's EZ-ZONE PM controller offers control options to reduce system complexity and the cost of thermal loop ownership. You can order the EZ-ZONE PM as a PID controller, an over/under limit controller or these functions can be combined into an integrated controller. You now have the option to integrate a high amperage power controller output with a high performance PID controller and an over/under limit controller in one space-saving panel mount package. A number of serial communication options are available to support your connectivity needs. Because the EZ-ZONE PM controller is highly scalable you only pay for what you need. This controller is available in 1⁄32 or 1⁄16 DIN panel mount packages. So if you're looking for a PID controller, an over/under limit controller or an integrated controller, the EZ-ZONE PM will make your life easier.
