70A Series Audible Alarm For Controllers with Relay Outputs
●Solid State Reliability, No Arcing or Mechanical Wear
●Easy to Install
●OMEGA® Series 70A temperature alarms are the latest development in solid state sound production.
When power is applied, a piezoelectric transducer operates as a solid state oscillator resulting in a loud, audible alarm tone.
OMEGA® temperature alarms are designed to give years of
trouble-free service. There is no arcing or mechanical wear, and they are rugged and easy to install. Only a 11⁄8" diameter hole is required for mounting by removing the front plastic nut, inserting unit and rethreading. Units are easy to operate. Simply connect to a temperature controller and 120 Vac power supply.
●Specifications
■Surge Voltage: 20% over maximum rated voltage applied for <1 minute
■Continuous: 100 hours continuous operation at 65°C with maximum rated voltage applied
■Intermittent: A duty cycle of 1 minute on, 5 minutes off, a minimum of 5000 times at room temperature with maximum rated voltage applied
■Life Expectancy: 5 years under normal operating conditions
■Storage Temperature:
▲-40 to 85°C (-40 to 185°F)
■Operating Temperature:
▲-30 to 65°C (-22 to 149°F)
■Humidity: Series 70A temperature alarms will operate after having been subjected to 95% relative humidity at 40°C continuously for 100 hours; after removal from high humidity, the unit should be allowed to dry for a minimum of 4 hours at room temperature before operation
