Watlow’s family of microprocessor based temperature and limit controllers provide an economical solution for applications requiring simple on-off control. These controllers and limits are available in a broad range of packaging options, allowing users to select the best version for their individual application. The controllers and limits are available with or without an operator interface and can be ordered in square 1/8 DIN panel mount, DIN rail mount or open board design configurations. The SERIES LV includes an operator interface for viewing and selecting the set point. A red, four-character seven segment LED displays the set point with a push to show process option. The set point selection is made with a continuous turn rotary encoder or optional tactile keys interface.
