. 7i77 – Trying to understand TB2 Pin 1 – VFIELD – FIELD Power 8-32V Pin 2 – VFIELD – FIELD Power 8-32V Pin 3 – VFIELD – FIELD Power 8-32V Pin 4 – VFIELD – FIELD Power 8-32V Pin 5 – VIN – FIELD I/O Logic Power 8-32V Pin 6, 7 – NC Pin 8 – Ground – COMMON
So – are pins 1-4 common to each other, not common and can be supplied different voltages, common but redundant to allow for greater current transfer. Everyone I have ask has given completely different and conflicting answers. Since I have no idea what the encoder current draw will be I will be supplying TB1 with its own 5V powersupply and thus W1 will short the 2 pins on the right (farthest from the DB25) I have a second 24V powersupply which I have wired to each pin 1-5 with ground on pin 8. My notes show I did this wiring 12/3/17 and have yet to actually power it up as have yet to obtain a clear definitive answer as to if this is proper or a potential smoke machine.
