I need 10 channels of 10A SPDT relay control via RS232.
I am considering three potential solutions. I need to consider cost, module failure risk, and since the boards do not seem to physically stack, space.
Industrial relay controller 16Ch SPDT + 8Ch ADC. $508
This solution is the easiest but is the most expensive.
Industrial relay controller 4Ch SPDT + UXP Expansion Port along with the XR Expansion SPDT 8 relay controller with general purpose relays. $425 I added this solution to my cart and then found the 3rd option which seems to trump this option.
Fusion 2Ch SPDT Relay controller with 16 GPIO or ADC and I2C - 10A SPDT along with the Fusion expansion SPDT relay controller 8Ch. $366
Perhaps there are more choices that I have not considered?
