Watlow’s Series 97 was a microprocessor-based controller with a single input, second auxiliary input and four outputs. Input 1 was used to measure temperature from a sensor. Input 2 could be utilized as a remote reset switch or a hardware lockout switch. With up to four outputs, the controller was versatile in handling applications that require a high/low limit, alarms, retransmit and communications. The control was so user friendly it could be set up to display safety and limit messages created by the end user to meet the exact application need.

The Series 97 limit controller was added to thermal applications to limit over-temperature conditions. It provided safety assurance against instances where a high temperature runaway condition could occur from a shorted input sensor or an output device that could fail in a closed position. The Series 97 was recommended for any application where thermal runaway could result in large product scrap costs, affect operator safety, cause damage to equipment, or create a fire hazard.

The Series 97 was manufactured by ISO 9001 registered Watlow Controls and reliably backed up by their three-year warranty.
