High-Limit Temperature Controllers
To protect equipment and personnel, these controllers shut down your machine when it gets too hot. Reset them manually to turn your machine on again. They're often used as a fail-safe system and for triggering alarms.
Set the actuation point and adjust other settings with the keypad. To read the temperature, these controllers use a highly sensitive thermocouple probe (sold separately). They have one or two mechanical relays that actuate circuits directly. Mount them into instrumentation panels with DIN cutouts.
Controllers that are SPDT (single pole, double throw) can turn one circuit from off to on (normally open) or on to off (normally closed).
Controllers that are SPST-NO (single pole, single throw) can turn one circuit from off to on (normally open).
Remote-reset controllers are best for hard-to-reach locations. To operate, you’ll need to wire the remote reset input terminals, and the sensor must be below the set temperature.
To mount 1/16 DIN controllers to a surface or DIN rail, add DIN-rail/surface-mount adapters. To convert larger cutouts to fit 1/16 DIN controllers, add DIN cutout adapters.
