Eusurplus has 7i76ED in stock, should have sinking outputs, but i am not sure.

Great find Tommy. Was looking for the E version not ED. What would I need to change to use ED? Sorry for the newbie question but the design / help all generally seem to be for the E version

48 points of isolated field I/O are provided for general control use including limit
switch and control panel inputs, coolant enable and tool changer control outputs.  Isolated
I/O includes 32 sinking inputs and 16 sourcing (7I76E) or sinking (7I76ED) outputs. Inputs
can  sense  5V  to  32V  signals  and  the  outputs  can  switch  5V  through  32V  signals.
Maximum output load is 350 mA. Outputs are short circuit protected.

It has sinking outputs instead of sourcing ones on 7i76E.
sourcing outputs = the outputs provide +VCC when on, so the relays/solenoids/LED's have a common ground and the Mesa outputs provide the positive voltage when turned on.
sinking outputs = the outputs sink to ground level when on, so the relays/solenoids/LED's have a common +VCC (12 or 24V positive) and the mesa outputs provide GND/ground/0V when on.

Note to self: do not edit long posts !

Here is a video that explains it much better than i do, just ignore the PLC parts and skip to 45 seconds.

Hi

I am currently also looking for a MESA 7i76e. So if anybody has any hints where to get one that would be greatly appreciated.

@cadpete - Who did you mean by JT? I am also from Perth, Australia.

Any hints on where to find a 7i76e (or 7i76eu) now? Both Eusurplus and Welectron are out of stock, plus I've been looking for one on local ads and Ebay for a year with zero success.
