Multi-channel signal acquisition application circuit
Function
In the figure,Sin1~Sin4 are external input signal,A0~A1 are strobe signal, and signal out is an external input signal of control system to accept.
The optocoupler in the circuit implements the isolated transmission of strobe signals. Amplifier of TE-N series implements the isolated
transmission of signals and isolated power supplement. The multi-channel strobe chips 4052 implements selective transmission of multiplex
signals.
Working principle
When the circuit works, the control system sends out the strobe signal A0~A1. Optical coupling isolation circuit transfers strobe signal to
multi-channel strobe chips 4052, and control the chip to correspond channel. External signal Sin1~Sin4 input to multi-channel strobe chips 4052.
After a chip strobe, strobe signal transfers to the signal input of TE _ N transmitter. TE_ N transmitter output the isolated input signal to control
system, thus it implements the control system and the external signal isolation circuit. Input power of TE_N transmitter and the input Vcc of strobe
signal transmission circuit are provided by control system. After strobe signal is isolated, transmission circuit power and multi-channel strobe chips
4052 power supply ISOVCC are provided by power distribution output Pout+.

Function
In the figure, Signal in is detected electrical signals, Signal out is electrical signals for control system of isolation transmission. VCC is isolated power
supply provided from control system. Typical power signal is positive and negative sine wave signal. 431 R1 R2 and R3 is voltage stabilizing circuit in the
circuit, and they can achieve zero adjustment of the input signal. Amplifier of TE_N series
achieve signal transmission function and power supply function
of voltage stabilizing circuit. R4,R5,C1 achieve DC output signal filtering functions.
Working principle
Supposing detected signal is 5V sine wave signal. When the input signal is passed through stabilizing circuit which is composed of 431,R1,R2 and R3,
input signal of TE_N transmitter become 0~10V sine wave signal. If the amplifier is the one which has 0~10V input and 0~10V output, TE_N transmitter output
would be output 0~10 v sine wave signal at this time. After passed through filter circuit which is compos
ed of R4,R5 and C1, the DC component of 0~10V
sine wave signal is filtered, and the output only have
±5V
sine wave signal.
Parameter
In the application, typical values of R1, R2 and R3 are 10KΩ, and reference Voltage of 413 is 2.5V. Component regulated voltage is 5V.
Voltage accuracy can achieve a variety of application requirements of high precision according to the resistance tolerance precision. Typical
application range of R4 is 2KΩ~5KΩ. Because signal output voltage is positive and negative, there will be a transmitter output signal current
return-irrigation phenomenon when the voltage signal output is negative.R4 should choose a smaller value in order to reduce the influence of the
return-irrigation current. C1 should be chosen low internal resistance capacitance. Normally ceramic capacitor with volume more than 10uF will be
suitable. Because C1 achieves the function of getting through AC and preventing DC. Large capacitance resistance and small capacitance value
can make AC signal distorted. The recommended value of R5 should be more than 100KΩ, and implements a DC signal to zero in the circuit. The
increase of value of R5 can make the time of DC signal to zero longer, and make the startup time longer. If load in circuit is too small, then the load
for AC will be increased, so that AC signal will be distorted.
Notice
Because the transmitter of TE_N series can not input negative voltage signal, it need to pay attention to narrow signal voltage amplitude and
have the necessary margin in the design. It can guarantee the normal work of the circuit and reduce the risk of signal distortion.

Routine zero and full adjustment circuit
24 V power input zero and full adjustment circuit
Function
Zero adjustment function by setting up adjustment resistor at the zero point can change the zero signal transmission, which makes the output
signal overall migration. Full adjustment function is also called the gain adjustment function, and it can change the ratio of signal transmission
through the set up corresponding adjust resistance at the full adjustment, and the isolation transmission proportion of input and output signal value
would be changed.
Usage
Adding and reducing negative zero resistance can reduce the zero of signal output. Adding and reducing positive zero resistance can increase
the zero of signal output. Adding and reducing negative full adjustable resistance can reduce the ratio of signal transmission, Adding and reducing
negative full adjustable resistance can increase the ratio of signal transmission. You can use potentiometer to adjust the output signal of zero and
full in practical application. As shown in the figure, the terminal of full or zero adjustment is connected to the sliding of potentiometer, and the both
ends of potentiometer is to the zero or full reference of positive and negative regulating reference . Sliding potentiometer to adjust signal full or
changing the ratio of rise and fall can also adjust zero and full of the output signal.
As shown in the figure, zero positive reference adjusting is different between 24V input product and other power input products, so the zero
adjustment circuit is also different. Adjusting the potentiometer to positive can increase zero or full of the corresponding signal. Adjusting the
potentiometer to negative can reduce zero or full of the corresponding signal. The maximum recommended range of potentiometer is 10KΩ~1MΩ,
detail resistance selection according to the adjustment accuracy. Choose larger resistance potentiometer for high precision fine-tuning. Choose
smaller resistance potentiometer for a wide range of rough adjustment.
Notice
The accuracy of transmitter of TE_N series is already 0.1%FS during production and before shipment, using the function of zero and full
adjustment will affect original accuracy. Due to the effect on temperature drift of external adjustment resistor and the stability of the potentiometer,
temperature drift of product will be changed, too.
The 1:1 ratio for positive resistance and negative resistance of full adjustment potentiometer is desired full adjustment. For the zero adjustment
potentiometer, the ratio between positive resistance and negative resistance, which makes the zero point of different products predetermined Zero
point is diverse. Please set the value of potentiometer according to actual situation.
