13:02, 1 September 2016SmartAD pinout.gif (file)39 KBJL (Connector pinout used by Sensoray Smart A/D boards (e.g., model 418, 419, 518, 618, 619). For each sensor channel x (in range 0:7), PHx/PLx supply excitation to a passive sensor (if needed) and SHx/SLx are the differential analog inputs. TREF and +12V ...)1
11:44, 26 April 2017StepperMotorDriver.png (file)4 KBJL (The input section of a simple stepper motor driver.)1

12:26, 7 March 2022Twin wire ferrule.jpg (file)11 KBJL (Twin wire ferrule.)1
15:55, 27 September 2017Vfd wiring no1.gif (file)9 KBJL (Don't do this! It creates a ground loop that may cause a DC offset voltage and/or couple noise onto the VFD's voltage input.)1
15:58, 27 September 2017Vfd wiring no2.gif (file)9 KBJL (Don't do this! It won't create a ground loop, but it may cause a DC offset voltage at the VFD voltage input because the 826 GND signal is probably not the same voltage as the VFD analog common (chassis ground).)1
16:00, 27 September 2017Vfd wiring yes.gif (file)7 KBJL (This is the correct way to connect a DAC to a VFD. Note that a dedicated conductor is used for the analog ground. This effectively makes the connection a differential pair, and completely avoids ground loop problems.)1
13:16, 4 March 2022Wire ferrule.jpg (file)884 KBJL (Wire ferrule crimped onto a stranded conductor.)1
