connect 2 AC heated bed keenovo 220 v/750 w

[yaman]

Hi all
I Have duet wifi and I have 2 heat bed 300X300 keenovo 220 v/750 w connected with ssr dc/Ac 10A
also I have PT100 Daughter Board and Thermocouple Daughter Board
I connect the bed heated bed out put to dc/ac ssr and the keenovo take power from ssr heated bed

my question is how to sent signal to the second heat bed via ssr
because it has only 1 output for heated bed
I read that I can connect 2 temperature sensors in Parallel and sent 1 signal to ssr so they work on and off together but is possible to run split ?
can I use 5 vdc out put signal that build in duet WiFi upper the input?
if yes how to setup that ?

You can run them split if you connect the second SSR and thermistor to a spare heater and thermistor channel. If you are not using the E1 heater/thermistor connections, you can use those. Use the M140 command to configure multiple bed heaters.

In that case you can connect the SSR control input terminals to of the servo outputs on the breakout board, between the PWM pin (+) and the Ground pin (-).
