| Use a 'srial chip | | 01/01/70 00:00 |
| But.. | | 01/01/70 00:00 |
| what's the problem? | | 01/01/70 00:00 |
| Re: Serial Chip | | 01/01/70 00:00 |

| Re: Why Damaged. | | 01/01/70 00:00 |
| Another suggestion... | | 01/01/70 00:00 |
| Yes, but... | | 01/01/70 00:00 |
| Schottky clamps ? | | 01/01/70 00:00 |
| Diode clamps | | 01/01/70 00:00 |
| Tranzorb | | 01/01/70 00:00 |
| Try this... | | 01/01/70 00:00 |

| My suggestion? | | 01/01/70 00:00 |
| Look for PLC discrete input circuits | | 01/01/70 00:00 |
| partially right | | 01/01/70 00:00 |
| Even a PLC wouldn't like this circuit | | 01/01/70 00:00 |
| OK, It's a switch - question to Scott | | 01/01/70 00:00 |
| Speed of the input | | 01/01/70 00:00 |
| at lower detection rates ... | | 01/01/70 00:00 |
| What I recommended... | | 01/01/70 00:00 |
| Steroids Desing | | 01/01/70 00:00 |
| Analyse the circuit | | 01/01/70 00:00 |
| to fully isolate | | 01/01/70 00:00 |
| how about answering | | 01/01/70 00:00 |
| That's obvious isn't it? | | 01/01/70 00:00 |
| it's not that obvious | | 01/01/70 00:00 |
| It's just ignorance | | 01/01/70 00:00 |
| opto couplers | | 01/01/70 00:00 |
| true enough! | | 01/01/70 00:00 |
| Not so strange | | 01/01/70 00:00 |
| Not strange, perhaps, but WRONG! | | 01/01/70 00:00 |
| It's just ignorance | | 01/01/70 00:00 |
| maybe you answered this one yourself | | 01/01/70 00:00 |
| still waiting | | 01/01/70 00:00 |
| No, though that might help | | 01/01/70 00:00 |
| is this a newfangled idea | | 01/01/70 00:00 |
| Downunder circuitry | | 01/01/70 00:00 |

| +5V supply, is it isolated? | | 01/01/70 00:00 |
| already asked and asked again | | 01/01/70 00:00 |
| Yes, last try before I leave the thread! | | 01/01/70 00:00 |
| The +5V is Isolated. | | 01/01/70 00:00 |
| incomplete answer | | 01/01/70 00:00 |
| Yes, what about the grounds? | | 01/01/70 00:00 |
| Scott, where are you? | | 01/01/70 00:00 |
| he left when we asked questions | | 01/01/70 00:00 |
| Still lost and confused | | 01/01/70 00:00 |
| you do not need a scope to answer the qu | | 01/01/70 00:00 |
| We cannot help you, if you do not... | | 01/01/70 00:00 |
| COM and E-GND | | 01/01/70 00:00 |
| still not answered | | 01/01/70 00:00 |
| just a minute ... | | 01/01/70 00:00 |
| SO let me rephrase: how many ohms betwee | | 01/01/70 00:00 |
| Getting Older | | 01/01/70 00:00 |
| if you want help, start with some answer | | 01/01/70 00:00 |
| Problem is much more complex | | 01/01/70 00:00 |
| what do you mean by "dying" | | 01/01/70 00:00 |
Scott, could you... | | 01/01/70 00:00 |
