The conveyor system is driven by a 240 Volt 50 Hz AC motor requiring a continuous 1 Amp supply. The conveyor has single direction operation.
The loading mechanism for the winder is fully automatic and only requires a single control signal of a logic '1' for load (and hold loaded) and a '0' for unload.
The winding machine requires six (6) bits into to the winder identify the number of turns to be wound. The 6 bit values between 2 and 40 represent the range of 200 to 4000 turns. (ie the number of turns is 100 times the input value) A single active low pulse (0.25s) is required to start the winding machine, and a single bit output (0 while busy, 1 when finished) is provided by the winder indicating the status of the winding task.
The sluice control of the hopper uses two (2) solenoid coils, each requiring 1 Amp for 0.25 second from a 12 Volt DC supply in order to open or close the gate. Assume the material flow is instantaneous on/off at the end of the 0.25 second open/close control signal.
Two Infrared beam sensors are used to verify the presence of a mould under the hopper and under the winder. Each provides an active low signal when an object cuts its beam.
The temperature measurement device provides a 0 - 5Volt analog signal indicating the temperature of the molten ceramic material over the range 0 to 10200C in 4 degree steps.

Externally Initiated Signals Other than interrupt there are followings externally initiated signals available in 8085 microprocessor.
Q. Explain working of Biased Clamper? Biased Clamper : The circuit of a positively biased clamper is shown in the figure. During the negative half cycle of the input signal the
Rise Time (t r ) During rise time voltage falls from 90% V a to 10% where V a where V a is the initial anode voltage. In terms of current time taken by anode curre
if a resistor is present between 2 branches in such way that its polarities are different to compare with one another so how we choose polarity of that resistor
Reproducibility and repeatability are measures of closeness with which a given input may be measured over again. The two terms cause confusion. Therefore, a distinction is made bet
Compound motor It is possible to arrange for part of the field coil to be in series with the armature and part in parallel This gives rise to a motor with a mix
LC Filter To the load resistance R L the ripple factor is directly proportional in the inductor filter and inversely proportional to R L in the capacitor filter. Hence i
Explain isolated I/O scheme. In I/O mapped I/O scheme the addresses allocated to memory locations can also be assigned to I/O devices. Because the same address may be assigned
