I need to design a switching circuits for this:
A tester device is used to test a controller(lets call it controller A). This controller have both input/ouput(analog and digital for each) which is currently tested by the testing machine.
I have to expand functionality of the tester so that controller B can also be tested(not at the same time). Controller B has same number of pin as controller A, but each pin each assigned different channel type(analog in controller A, digital in controller B, vice versa).
So I will have to make separate wiring harness for controller B, and have to switch back and forth every time.
So I decide to use relays to accomplished switching. There are approximately 35 pins with channel type mismatched, I am thinking about using six 6pole-double throw relay which will switched for desired configuration. I am using this relays http://www.digikey.com/product-detail/en/te-connectivity-potter-brumfield-relays/R10-E1Z6-V430/PB775-ND/813841. My question is given the situation I just described, are there better way(I may have missed) to accomplish this?
Notes:Another issue is pins are group by connector on both DUT and tester side. And signal that needs to be switched are not necessarily in same connector.
