Limit and Alarm Controllers

 

Limit controllers are added to thermal applications to monitor an over-temperature condition as a safety precaution. Limit controllers provide a safety assurance to guard against high temperature runaway conditions resulting from a shorted input sensor or an output device that fails in a closed position.

 

Watlow limit controllers provide agency approved performance in safety limit applications. All are available with industry standard I/O options. Watlow limit/alarm controllers are designed and manufactured to withstand harsh industrial environments.

 

The multi-loop limits and alarms are a low-cost solution for multi-channel, redundant temperature monitoring. These limits and alarms can continuously monitor thermocouples, RTDs or thermal switches, making them ideal for multi-zone applications.
