| Jun 23 at 23:11 | comment | added | Hazardous Voltage | @FabioBarone A1: 27 Volts coming from the zener diode. A2: to a zener diode of 4.7 V, it is used for measuring the under voltage. A3: The datasheet: semiconductors.es/semiconductors.php?id=720559 A4: D2:lcsc.com/datasheet/… D1:lcsc.com/datasheet/… | |

| Jun 23 at 23:06 | comment | added | Hazardous Voltage | @periblepsis I think R7 and R11 do this job they make a schmitt trigger here | |
| Jun 23 at 23:03 | comment | added | user319836 | My first thought is the relay is too much for the LM324. Need a datasheet for the relay. | |
| Jun 23 at 22:59 | comment | added | Fabio Barone | Q1: What is the supply voltage for the op-amps? Q2: What are the inputs of U1:2 connected to? Q3: For RL1, what is the coil drive requirements (voltage & current)- datasheet please? Q4: For D1 & D2: links to datasheets please. Cheers. | |
| Jun 23 at 22:58 | comment | added | periblepsis | Did you design in some hysteresis? (I'm not looking yet. Just asking as it is the first thing that comes to mind when you talk about levels and chattering.) | |
