On the new Multiplus-II, the K1, K2 'relays' are described in the Appendix as "open collectors", which appear to be connected to a microprocessor directly. The Ground then appears, looking at the image, to be the ground of the MultiplusII integrated circuit. While that is the appearance, the words in the manual indicate that those "relays" have the same function as the original Multigrid relays, which appear to be isolated, and able to be used as a relay. (On that model, there was an "K1 relay" & a "K2 relay) Does anyone actually know, for example if a voltage (like 48Vdc) is connected through the open collector when open, say via the K1, terminal, if that is going to adversely affect the Multiplus-II? Put simply, I wish to use at least one as a 48V external fan relay (can't use the main aux relay, used), so is that possible to do, for say a 100mA separate relay for a fan, @48Vdc coil?
