    Intuitive Watlow® PM Plus® PID/Integrated Limit Controller

    July 1st 2024

    The versatile PM Plus® Controller from world-leading Industrial heating solutions provider Watlow® provides one of the markets most advanced and intuitive user experiences.

    This is an adaptable device that can function as a PID (Proportional – Integral – Derivative) controller to regulate temperature, flow, pressure, speed, and other process variables in industrial systems or as an integrated control station to govern multiple processes.

    PM Plus Design and Features

    Like the original EZ-ZONE PM, the PM PLUS can be ordered as a PID controller, or an integrated controller with multiple functions combined into one.

    The updated PM Plus remains back-compatible with legacy EZ-ZONE PM controllers but is now available in 1/8 DIN horizontal and vertical package format sizes and with a revised design  featuring  an enhanced user interface for easier programming and readability with a SMOOTH-TOUCH™ keypad to provide an industry leading user experience.

    Upgrades also include an intuitive menu flow allowing the controller to be easily configured. The PM PLUS further improves the user experience by reducing the complexity at the front of the control while eliminating the dependency of cables when configuring the product.

    PM Plus continues to offer Bluetooth® connectivity via the EZ-LINK™ mobile app for remote access capability and full descriptions of parameters and error codes.

    EZ-Zone family

    PM Plus is a member of the EZ-ZONE® RM Rail Mount Controller: The EZ-ZONE family of rail mount controllers that simplify thermal system management by providing a central control and management hub.

    The EZ-Zone family comprises six functional modules: an integrated on-off or PID control, monitoring and over/under temperature limit controller module, a high-density on-off or PID control module, a high-density limit-only module, an input/output (I/O) expansion module, a high-density monitor/scanner module and a data logging and field communications access module. Systems can be configured by connecting any combination of module types to address specific application needs.
