#37429 - Reading Sensors |
Hi,
here are two methods that I intend to use, but need to confirm before doing so. Please let me know if something terrible is hidden in them: 1. I want to read the status of a 24v dc contact sensor (like low oil level switch etc). What I intend to do is use a level translator like the 1489 like this... COnnect the 24v line to 1489 (input). A 10k resistor in between them with the other end (of the resistor) connected to ground. The output of 1489 to the Port. IS this OK? 2) I want to drive a 12/or/24v dc LED and I intend to do it like this... COnnect the Anode to the power source, the cathode to the output of an hex inverter(7406) via a 1k resistor, and the '06 is inturn connected to the port pin. Are the above methods ok? REgards, Harsha |

| 1489 and 7406 good Enough? YES! | 01/01/70 00:00 | |
