2. WHAT IS THE TOPIC?
• THIS QUESTION IS HARD TO ANSWER HONESTLY
ONLY GENIUS CAN ANSWER(TOTALLY NOT CLICKBAIT)
3. THE MAIN TOPIC!!
How is 4- 20 mA signal converted/related to 1 - 5V signal?
*TO ANSWER THIS QUESTION WE MUST FIRST UNDERSTAND WHAT IT
MEANS SO YOU WILL NEED A GOOD AMOUNT OF FOCUS
4. • The general input impedance of 4-20mA is 250-300 ohm, which is not easy to have
interfered.
• But maintenance measurement is more troublesome;
• 4-20ma DC signal can provide power. In addition, it is not affected by the load size
within a certain range, and has strong anti-interference ability.
• 4-20mA can realize two-wire transmission, saving wires.
• The current signal is suitable for long-distance transmission, but the current signal
has weak anti-interference ability, and shielded wires are generally used.
• Editor notes : pretty long? (I know) but it is what it is just read it your FUTURE having high hope on you
5. NOW WE KNOW WHY WE USE 4 – 20MA
BUT WHAT IS 1 – 5 V???
The answer is on next slide
Tbh making this topic kinda hard to understand but it cant be help but it is what it is
6. -1-5v are generally high-impedance inputs and are susceptible to interference. But
maintenance, measurement and calculation are all very convenient.
-1-5V, is active, three-wire system, or four-wire system.
-The voltage signal is stable and anti-interference is strong, but it is not suitable for
long-distance transmission (with voltage drop);
7. SIDE BY SIDE COMPARISON
4 – 20 mA 1- 5 V
not easy to have interfered susceptible to interference
maintenance measurement is more
troublesome
maintenance, measurement and
calculation are all very convenient
two-wire transmission, saving wires. active, three-wire system, or four-wire
system.
is suitable for long-distance
transmission
not suitable for long-distance
transmission
shielded wires are generally used.
8. BOTH SLIDE TELL THE DIFFERENCES
BETWEEN THOSE 2
BUT How are they related?
9. RELATIONSHIP BETWEEN 4-20MA AND 1 – 5
V
• Both is single and not taken
• Both is same species
• Both can be calculate
• Both have family (vin diesel approve)
12. CLOSURE
I hope you guys understand the topic even though it’s understandably confusing and stuff
like that
But like every geniuses said ‘surpass your limit and go beyond plus ultra’
-random guy from internet that is genius-
That is all for today and thanks
