Looking to see if anyone has implemented three interposing relays in a hardwired 2oo3 interlock circuit.
We are adding new PLC based interlock to an existing hardwired circuit and 2oo3 has been proposed for perceived reliability. Is there a packaged module with three ice-cubes, already wired as 2oo3? Otherwise we'd just hardwire the interconnecting 2oo3 circuit contacts from the three relays.
