CAL Controls MaxVU RAIL Temperature Controller/Transmitter and Limiter

The CAL MAXVU Rail is a DIN-rail mounted temperature and process controller that's easy to install, configure, and read. It's a great fit for general industrial and scientific applications that require a reduced back-panel footprint, centralized control, or minimal front panel components. These slim modules offer PID control for stable and efficient temperature and process control, transmitter functionality for monitoring and data collection of process measurements, and an FM-approved limit function for machine protection.

MAXVU Rail incorporates the latest OLED technology display for high contrast text/graphic display with a wide viewing angle, easily visible to configure in bright sunlight or a dark control panel. The quick setup menu can be accessed from the front keypad. It includes the most common parameter settings, prioritized so it defaults to the most common option. Other parameters are available through the full menu.

MAXVU software is available for fast setup using the controller's front-access configuration port. The software features a logical menu-driven interface, tables with drop-down menus, a graphical setup wizard with a help panel. It also lets you easily save configuration files and print reports of controller settings.
