The 1/8 DIN Partlow 1801+ limit controller is part of a range of new generation Plus Series limit devices that share the same distinctive styling as the Plus Series temperature controllers.

In addition to the 1/8 DIN Partlow 1801+ controller model, the Partlow Plus Series of limit controllers also includes the 1/4 DIN Partlow 1401+ Limit Controller and the 1/16 DIN Partlow 1161+ Limit Controller models. These controllers incorporate numerous improvements in product specifications, communication, display interface, and software, which provide ease of use, delivery, and value per dollar.

More versatile and user-friendly features have been added to the limit controllers in the Partlow Plus Series. These features include digital inputs, a simplified human-machine interface, jumperless and auto-hardware configuration, 24VDC transmitter power supply, and MODBUS communication. The benefits of these features include time savings (up to 50% on product set-up) and the virtual elimination of the possibility of operator errors.

The Partlow 1801+ limit controller offers fail-safe protection and prevents damage to equipment and products. These limit controllers shut down a process when a preset temperature is reached and can't be reset by the operator until the process has returned to a safe operating condition.

Use your Partlow 1801+ limit controller in any application where protection against out-of-range temperature conditions is a critical requirement.
