Upgraded SSR

This is built to order and normally takes less than 1 week to completed so please have patience while it’s being built. Each is tested before being shipped out. This will fit direct in your current HR relay board frame so more from a mechanical relay system to a solid state. Also has replaceable relays if one just so happens to go bad. If your relay is not located behind the screen you are going to need an updated bracket from us. These are 3D printed and include 3M tape so you can stick it on your side wall next to the screen area.    Here are some details: A triac is the device that is used in a Solid State Relay (SSR) – more on this is a second.  The design also includes a Zero Cross detector. When you want to control a AC device – you usually want to Start and Stop the device as the AC voltage goes thru zero volts.  House AC voltage is normally expressed as 120 vac.  This is actually the RMS (Root-Mean-Square) voltage with the actual Peak voltage at 140v.  A circuit called a Zero-C
