4-20 mA Control/Alarm/Indicator
Model: CT-2012

OVERVIEW:
The CT-2012 4-20 mA Controller/Alarm/Indicator offers accurate and reliable measurements for various applications in industrial environments, making it an essential tool for monitoring and control tasks.

FEATURES:
◆ 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

EACH UNIT INCLUDES WITH:
◆ Instruction Manual
◆ Case holder with screw

OPTIONAL ACCESSORIES:
◆ Data Acquisition software, SW-U801-WIN
◆ RS232 cable, UPCB-02
◆ USB cable, USB-01
