WebBy adding a 120-ohm resistor at the end of an RS485 transmission line, the signal will be dampened by the resistor instead of reflected into the bus. If the value of the resistor does not match the characteristic impedance of the cable, reflection may occur. In most RS485 configurations, two termination resistors are used.

WebMar 3, 2024 · The coil diode will protect the switch contacts in whatever you are using to switch the relay, It is not protecting the relay contacts themselves. For instance if the headlight main beam relay has a diode , the diode is there to protect the contacts in the steering wheel stalk, and not the contacts in the relay itself. WebJun 19, 2024 · A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated. 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. Do I need a resistor in series with a relay? 1 ... doctor gillette orthopedicWebApr 27, 2024 · 2 Answers. Assuming that by "ideal coil" you refer to a purely inductive coil with an ohmic resistance R = 0, you can assume that, for the purposes of calculating total resistance, the coil is simply a short-circuit that bypasses the resistor in parallel. Computing the parallel resistance gives R (parallel) = 0, which is indeed what you arrived at! doctor ghost subthai
