Lutron CT-2012 4-20 mA Control/ Alarm/ Indicator

Made In Taiwan

Features Lutron CT-2012 4-20 mA Control/ Alarm/ Indicator

Input : 4-20 mA DC, linear.
User can default the desired display value between -1999 to 9999 ( decimal point can be selected to DP1, DP2, DP3 ) and all the preset data will be saved into the memory circuit permanently.
According the 4 to 20 mA input signal, user can preset the desire display value between -1999 to 9999 ( decimal point can select to DP1, DP2, DP3 ). Until set the display value, all the data will save into the memory circuit permanently
When CT-2012 cooperate LUTRON’s 4 to 20 mA transmitters ( or any other transmitters if it build 4 to 20 mA output signal ), whole system will become the high performance Controller/Alarm/Indicator for following measuring functions : Humidity, Light, pH, Dissolved Oxygen, Conductivity, Vibration, Pressure, Sound,
Temperature, RPM, Hz, Load cell ( Weight, Force ), Potential ( Angle, Level ). ACV, ACA, DCV, DCA, WATT….
Easy to adjust the function factors by push button on the front panel. Control output : 2 points ( COM, NO ).
Alarm output : 2 points ( COM, NO ). Control Relay will make action when the reading value reach to control value.
Hysteresis value setting for control and alarm function.
Large red LED display, high brightness and easy to read.
Microprocessor circuit ensures high accuracy and provides special functions and features.
DC 12V power supply output.
RS232/USB computer interface.
Power : 90 ACV – 264 ACV, 50/60 Hz.
Standard 96 X 48 mm DIN case.
Optional data acquisition software.
