Relay board 8 Channel High Power Race Car Hot Rod

  
8 Channel 12v Relay board hotrod race car Project EFI Trigger Input Selectable. This board is a Massive 240 amps capable and will accept up to a 3/0 input cable. The board measures 7"x10" with mounting holes to accommodate a #8 screw with standoffs (mounting hardware not included). Each of the 8 relays are independently fuse protected with a fuse size you choose up to 30 amps per relay. The fuses required are standard blade type fuses found at any auto parts store. The only fuse included will be the 2 amp fuse for the key on SW+ circuit shown in pictures. Each of the 8 Relays are also input trigger selectable (positive or negative) for optimal flexibility. Each relay output also has an output status indication light as well as 2 position terminal block that will hold up to a 10 gauge wire. If dual fans for example need to run at the same time, one relay can be used as long as the total current of the 2 fans do not exceed 30 amps or they will need to be separated to individual relays and instead share the same input trigger. The coils for each relay is isolated from the main battery cable input lug due to the nature of EFI System where dirty grounds need to be isolated from electrical noise. The input terminal has a key activated (SW+) and a GND.

In an EFI install you would not use chassis ground for the GND input and should rather be installed directly to the battery as well as the (SW+) activated by the key. The key on SW+ also has a power on light when the board is activate. If EFI is not desired then the GND can go to chassis ground. Take the hassle away from your project and simplify it with ease and flexibility. Each board is built to order in 3 days.
