I have an application that is space limited
I need 32 relays in a small space
looks like the best way is 2 16 I2C relay boards, stacked on spacers
(yeah, access is limited, using pluggable connections, and my application is all low voltage)
Your documentation does not list height of the pcb, but does list min 0.25" to base
Travis,
we are using the 3amp version of this board
We currently have the non pluggable board…looking to see if the pluggable will fit for the next order
Proposed setup:
stacking 2 boards from a chassis on standoffs…
16mm+16mm+ PCB thickness board 1
+
?mm airspace between boards
+
16mm+16mm+PCB thickness board 2
+
?mm airspace between bottom board2 and chassis
This look correct?
any recommends for airspace distances?
How about mechanical dimensions / datasheet on the pluggable connector please?
Are you saying that you have DPDT relays on your board? That is the only 3 amp relays we carry. Just want to confirm that you actually have to have DPDT relays as that makes a very big difference on board height due to the double row screw terminals.
That’s correct. DPDT relay controllers have one set of pluggable connectors which mount to the bottom side of the board, and there other set mounts to the top side of the board. I would highly recommend that you have a board in hand before you make any further design decisions as it is a bit odd.
