My config
M308
M308 S0 P"temp0" Y"thermistor" A"Bed" T100000 B3950 ; configure sensor 0 as thermistor on pin temp0
M950 H0 Q10 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0 (if NOT using SSR - delete Q10)
M307 H0 R0.678 K0.477:0.000 D4.24 E1.35 S1.00 B0 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0

If you take the 40DA variant of the relay as I understand your post, it will be able to handle the required currents with ease.

On a side note: try to keep GCodes and comments in sync - if, as in your M143 line from the config, you set the upper limit (e.g. Snnn) to 120 °C, don’t tell the world it is limited to 100C
