Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).itosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).
Pilot Duty Ratings. A Relay can be assigned a Pilot Duty Rating when it is used for switching loads on another relay, or solenoid valve coils. It can be a direct current (DC) rating, or an alternating current (AC) rating, as shown in the table at the bottom of this post. The Pilot Duty Ratings are obtained after performing product qualification tests.
An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. The ANSI device number is 50 for an instantaneous over current (IOC) or a Definite Time Overcurrent (DTOC). In a typical application the over current relay is connected to a current transformer and calibrated to operate at or above a specific current level.
