Two Mesa 5I20

Hello
For the combination with the 5I24 with a 7I48 + (3X 7I37TA) + (7I52S) what I still need for it?

Sorry, I am confused now.
Can you tell us what hardware you already have and how many servo channels and IO pins you need?

So far I have a 5I20 to 2X7I37TA and 1X7I48
The IO pins are exhausted
There is also a tool changer and a fourth axis.
Whether I build the two áls servo system or with steppers I'm still hesitant ............

Mfg Dirk

I see two cost-effective ways to add more IO.

1) Add a 5i24 and another 7i37TA = $198 for 8 outputs and 16 inputs
2) Swap an existing 7i37TA for a 7i44 and a 7i84. That is $148 for a net gain of 16 inputs and 8 outputs. (and another $79 gets you 16 more outputs and 32 inputs)

But: I think that the 7i37TA IO can be used for step-generation and encoder counting, whilst the 7i84 (and other smart-serial cards) can not. Though the 7i84 has two on-board MPG counters.

Good morning, I need cards MESA 5I20 FPGA PCI Anything I/O Card LinuxCNC 12 Axis. Does anyone have one available for sale?

If you don't mind updating LinuxCNC, you might be better off with more current replacements for the 5I20:

PCIE --> 6I24-16
Ethernet --> 7I80HDT

The 5I20 is a 20 year old card...
