Watlow Limit Temperature Controllers

Limits monitor the process value where thermal system protection is needed, closing a contact output for normal operation and opening that contact to shut down the process or equipment when the value is outside the safe range. Various configurations offer user-selectable or fixed-configuration sensor options including thermocouple, process, RTD and thermal switch inputs as well as user-settable or fixed limit values. Models with displays have user-selectable temperature units. Other features include sensor break protection, industry standard I/O options and ULŪ and CSA approval. EZ-ZONE models are RoHS compliant. Limits have FM approval for performance in safety limit applications. Watlow limits are designed and manufactured to withstand harsh industrial environments and come with a three-year warranty.
