Limit Alarms

Process limit alarms monitor sensors and trip a relay output if the input exceeds a user-defined hi/lo setpoint limit.

Configuration is easy with Windows software, push-buttons, switches, or pots for settings depending on the series.

Models include Universal Input, DC Voltage/Current Input, AC Voltage/Current Input, Millivolt Input, Thermocouple Input, RTD/Resistance Input and a range of accessories

Limit Alarms

Process limit alarms or Trip Amplifiers monitor sensors and trip a relay output if the input exceeds a user-defined limit.

Models consist of AC, DC, and loop-powered limit alarms. Configuration of the models with Windows software is very easy.
