Solid state relay upgrade for Formbot T-Rex 2+ Heated bed
With Solid-Stae Relay(SSR) upgrade kit, you can control Heated bed via Printer software/Firmware/gcode. Solid state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.
What is SSR?
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals.
Inherently smaller and slimmer profile than mechanical relay
Totally silent operation
SSRs switch faster than electromechanical relays
Increased lifetime, even if it is activated many times, as there are no moving parts to wear and no contacts ensuring process stability
Output resistance remains constant regardless of amount of use
Clean, bounceless operation
Much less sensitive to storage and operating environment factors such as vibration, humidity, and external magnetic fields.
