Topic: Relay output - keeps combining channels when connected

Need some help with this basic flip/flop circuit.   I have the input on CH0, flip/flop conversion on and outputs to the relay on 6/7.  In test mode, everything is working but when connected to the relay + inputs (for switching on/off), it seems to combine both channels.   I'm a bit new to this but am impressed with the Canny's capabilities....probably overthinking the circuit.   I've attached the circuit file also.

Thanks.....

Re: Relay output - keeps combining channels when connected

I'm starting to think the Gruner 750 Relay requires too much for the Canny to handle on the switching.    Anyone tried this yet?

Re: Relay output - keeps combining channels when connected

I did not find the coil current/resistance of the Gruner 750 Relay offhand.
You can check the coil current by amperemeter at the maximum voltage you are using. If it higher than 100 mA, then the power of the one CANNY 7's channel  is not enough to switch it. But you can use CANNY's channels in parallel or use an intermediate relay/FET (preferred)

I simplified your diagram a bit:
