Check the listing for details. 4~20mA PLC Signal Generator Current Transducer Test Two Wire Output. Condition: New. Listed at 8.83 USD. 4~20mA PLC Signal Generator Current Transducer Test Two Wire OutputProduct Image: Product Description: Description:1. LCD (with backlight);2. 9 programmable output (can simulate the actual environment of dynamic testing, each section can be set up t running time /A current /b current);3. digital rotary encoder adjustment (the use of potentiometer, easily affected by temperature and humidity, the resistance value will change);4. can be connected to the positive and negative (two-wire system, no matter how wiring, can work, will not burn meter);5. high precision, good linearity (display accuracy of "0.05" of the decimal point, the actual output accuracy of + 0.5%) (two);6. imported chips, ultra-low power consumption, no heat, more stable output;7. the shell is beautiful and easy to install; System operation:The working mode of the signal generator is two: 1, manual adjustment mode; 2, dynamic output mode;Manual mode adjustment output current: rotary encoder knob, clockwise current increase, counter clockwise current decreases;The manual mode saves the output value, short press encoder knob, after the opening, the screen shows "...", saved successfully, output the next boot is the value stored value; when debugging equipment, we need to adjust the random output values, as long as you don't press the encoder knob after reboot or the original save this value;Dynamic output mode: is a programmable set of good curve continuous automatic output;Parameter setting: press the encoder knob, after 5 seconds, enter the set state, the first parameter "model": the screen FUNX X said the number of segments in the curve, the rotary encoder knob to adjust the value of X, X=0 said there is no curve in manual mode, X>0 uses dynamic output mode;After adjusting the first parameter "mode of operation", press the encoder knob again. If X=0, exit the setting mode and enter the manual mode. If X>0, then enter the first curve;Each curve is provided with 3 parameters, "tXXX" running time "AXXX" "bXXX" to end the current starting current, so enter the first curve set, the screen shows "t1XX", the rotary encoder knob to adjust the value of XX, the running time adjustment range 1--99 seconds;Then click the encoder knob into the first curve of the "start current" settings, the screen shows "A1XX", the current setting range 3-21 mA;Then click the encoder knob to enter the first curve of the "end of the current" settings, the screen shows "b1XX", the current setting range 3-21 mA;Second curves and so on, until set the number of the end of the set, automatically exit the set state.If the next time just need to change one of the parameters, the parameters remain unchanged, then set the length of the encoder button for 5 seconds can be set directly out of the state.
