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.

Universal Input - Limit Alarms	DC Voltage / Current Input Limit Alarms	AC Voltage / Current Input Limit Alarms

Universal Input Limit Alarms allow you to compare a wide variety of temperature, voltage, and other input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation.	DC Voltage / Current Input Limit Alarms allow you to compare 0-100V DC, ±100V DC, or 0-22mA DC input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation.	AC Voltage / Current Input Limit Alarms allow you to compare 0 to 20A AC current input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation.
Millivolt Input - Limit Alarms	Thermocouple Input - Limit Alarm	Frequency Limit Alarms

Millivolt Input Limit Alarms compare ±100mV DC sensor input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation.	Thermocouple Input - Limit Alarms allow you to compare thermocouple Type J, K, T, R, S, E, B, or N temperature sensor input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation	Frequency Limit alarms allow you to compare 0-50KHz frequency or 0-65535 pulse input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation
RTD / Resistance Input - Limit Alarm

RTD / Resistance Input - Limit alarms allow you to compare Platinum, Copper, or Nickel RTD temperature sensor input signals against user-defined hi/lo setpoint alarm limits for failsafe relay trip activation.
