1) What your suggestion on Post #34 circuit? As per that circuit both relay should connect at the same time it connects in alternate way, like one is ON and other is OFF, i am interested to understand logic of this circuit
2) Post 39 Falstad circuit really helps me to understand the operation of the circuit, but that circuit operates on 400 ohms coil resistance of relay, but in my case i am using T7CS5D-24 relay parts from Tyco, its having 1600 ohms coil resistance, what type of modification i have to do to drive this Tyco relay? One limitation is i can not increase the power supply from 24VDC
3) Can you suggest me any Op-amp part number which is low cost and perform the operation, what we are looking for in Post #34 circuit.
4) This 'Full-wave Rectifier with Smoothing Capacitor' circuit is efficient to generate smooth 24VDC (i mean pure 24VDC)? do you know any such compaq part which perform this action?
1) Thanks for appreciation, yes i would like to operate the second relay by inverting the signal of first relay in Post #34 circuit, actually i tried diffrent configuartion by modifying the circuit but i am unable to do that, could you please modify Post # 34 on falstad and post a new falstad link? In case application i dont require 2 contacts thats why i have finalized SPST relay
2) In Post 39 i have tried to change capacitor value to drive 1600 ohms coil of relay, but eventhough i am incresing the value above 300uf, relay should not operate, could you modify that Post#39 circuit for 1600 Ohms relay? (My relay specs are Rated voltage 24VDC, operate voltage 18VDC, release voltage 1.2VDC, coil resistance 1600 ohms 10% tolerence, rated coil power 360mW
3) Withstand voltage means supply voltage of op amp? can you elaborate more on this " For instance, the inputs are not supposed to be exposed to a differential of greater than +5V or -5V. This may or may not occur in your project."
4) Actually i am more interested to impant readymade 24AC to 24VDC power supply module, if i will get it in low cost
5) On Post#39 circuit, i found that first op amp works on 28VDC and second op amp work on +- 15VDC, i am unable to understand reason why you did that? because i think both op amp are operate as voltage comparator mode right? and one more thing cant we operate both op amp on 24VDC only, if its possible what are the necessary changes require in Post#39 ciruit? why i am asking this because if both op amps operates on diffrent voltages then i have put extra circuit for that voltages for 28VDC and +-15VDC, it increase the board size and cost of the circuit, let me know your thoughts on this.

1) actually earlier you said that this second relay might operate as in inverting mode in Post #34 circuit, can you make the necessary changes in this circuit if we want to operate both this relay invertly.

3 ) you mean to say i have to order a op amps which should operate on 0 to 24VDC right? what are the other factors i have to concern? yes you are right i need to find out the limit of each components, that is why i am planning to test this circuit first on general purpose board and after that i will move forward to proto type stage
4) Yes i tried to operate both op amps by changing the voltage level
5) one more question, can you design some logic circuit in falstad for CLK pulse input of op amp? actually i thoguht its better if we can take multiple input from diffrent port of microcontroller (for example 3 diffrent port of microcontroller) if all 3 input logic is fullfill then only this logic circuit would generate pulse (5VDC, 1KHz, 50% duty cycle), by doing that we can move forward to next level of redundant design, let me know your thoughts on this

i have one question with post # 49 circuit, you have changed the op amp voltage also, now first op amp is operates on Min 2 to Max 26V, and second op amp operates on Min 2 to Max 23 V, those supply voltage is mandatory to get +- 2VDC tolerence?
