Dear Klaus,
I will set the relay with a push button and reset with a comparator circuit. I have also checked the ICs in the market but I couldn't find a suitable product and I want to build the circuit with discrete components. The single solution seems to be the usage of a monostable...
Dear Klaus,
Thanks for the reply. Could you explain the issues from the safety aspects? I need to reset relay when the temperature of the system exceeds the critical level. Also, what do you mean by the "identical circuit"? Thanks for the support.
Best regards,
Serkan
Hi all,
I want to drive latching relay for a protection circuit. Reset coil of the relay needs 50ms and 250mA pulse signal for the reset operation. I will drive it with a comparator circuit using an opamp. But when a protection state occurs, comparator drives continuously the reset coil and the...
Hi All,
I have a 1V 50kHz sine signal source and i want to amplify this signal to 50V 1A sine signal source using BJT's. Can you suggest me an amplifier circuit, which topology is suitable for this amplification? Thanks.
now i monitored with scopometer.i can see my perfect pwm :) but when i connected pwm signal to pwm input of lmd , i didnt monitor pwm signal, it lost.if i reset the pic i can see the signal.
Hi all.I must control speed and direction of a 12v dc motor for my graduation project.i try with lmd18200.but i have some problems.i connected to pwm input of lmd18200 610 hz. pwm signal from PIC16f7877a.but it doesnt work.if i connect 5V to pwm input it works , can you help me.which frequency...
hi all.ı try to write asm code for up-down(0000-9999) stopwatch with 8052.but ı have some problems about down stopwatch.can you offer a powerful algorithm for this problem?ı attached .hex .asm .dsn(proteus) files.you can see problem.for example; when you see 0130 in displays,open "up-down...
hello.At firstly I'm sorry for my terrible english:cry:.I design a circuit for car body control unit(BSI).I will control windsheld wipers(with rain sensor),car ceiling lamp,headlights,central locking etc. automatically with PIC16F877A.But ı have some problems about lightening system.I can use...
