Transmitter is physical device transmitter is get the signal of analog means it will give the electrical out put means 4-to 20 mA according to the mA we can find out the level of liquids
in side the vessel 25% or 50%.

Answer / ayaz

Tranmitter input supply in voltage 24vdc and output 4-20 is standard output signal and use for Transmitter health monitor.

i am confusing about differential pressure transmitter as i seen so many DPTs in different ranges how can we calculate level and flow with mmh20 plz tel me

We have a Yokogawa Micro-XL DCS, which is having around 300 I/O, but whenever there is any wire gets grounded in field, the 24v supply to all loops gets dipped & all the indications at DCS goes to IOP(shows input open), at present we have fixed 500mA fuses in all the lines but which does not working. Does it required to replace with lower amps fuse, then how much or is there any other solution for this.

A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
