Trying to Figure Out Hardware

17 May 2019, 05:29

We have a ongoing project that uses Opto22 hardware. We want to move to open source software and cheaper hardware along with something a little smarter than a PLC. The hardware we currently use is:

I think I have figured out what we would need for the most part:
RevPi Connect+
RevPi Analog-IO Module (2)
RevPi Digital-IO (2)

The piece(s) I am struggling with finding "equivalents" for are the OMR6T, which is a mechanical power relay output module. I have seen a little info about relays and the RevPi but have not found any info on how it works and how to set it up.

We also use some Advantech hardware, switch, LTE gateway, Ark computer (hopefully that can go away too).

Any help would be greatly appreciated as I am new to the RevPi world and really want to make this hardware work as a replacement. I do understand a control system based on a RevPi would be completely different than the Opto22 control strategy we currently use.

Thanks in advance.

Dear Colin, the RevPi Connect has one relay output. ... t-connect/
You may control it using the variable in the proces image RevPiLED, bit 6. But in general you may use the digital IO modules together with industrial relays as we did i.e. with some exponats.
