I want to submit this device for our test racks. For what we're doing, this covers the task (with some additional external hardware). But what's got me perplexed and I was hoping for some help, how does anyone use this to drive relays? The current out for the digital I/O is very low. The DIN rail SSRs I'm looking at I believe need something like 100mA. So how do others drive relays without building a custom board? I don't see any DIN rail mountable relay driver boards. Anyone got any advice?
