Help me understand how to wire up 230 V heaters
-
What pins on 6HC can I use to control 3 230 V heater? Or do I need an extension board?
Info about the heaters:
Each heater has its own solid state relay.
Top heater, 500 Watts, 5A for 120VAC and 2.5A for 240VAC systems
Middle heater, 350 Watts, 3.5A for 120VAC and 1.75A for 240VAC systems
Nozzle heater, 250 Watts, 2.5A for 120VAC and 1.25A for 240VAC systems
Many pins can be used as the temperature output control. Your 3D Printer Controller (or motion controller) pins can be as below:The standard extruder output (E0, E1, E2, etc). These are usually rated at the same voltage as your main power supply (12VDC or 24VDC).
Any available expansion pins. These can be determined by checking the 3D Printer Controller specification pins. -
@qlqlo most SSRs accept 3 to 32V on the control terminals. With a 6HC powered from 24V I suggest you use any three of the OUT pins to control your SSRs. Using IO_OUT pins might not work because although the voltage is 3.3V they have series resistors, so might not be able to provide sufficient current.
