The series 923L limit controllers can be programmed for either high- or low-temperature limit detection and provide a relay output to interrupt power or signal an alarm. Featuring a waterproof and dustproof front-panel display and compact 1/16 DIN package, they can retain a peak temperature and record how long it stays above the application temperature. The controllers are available with two separate relays to trip an alarm when one limit is detected and can then perform another function upon reaching the second set point. Reset can be accomplished via the front panel or remotely by optional contact input or digital communications.
