Yep, 10 amps continuous load on each relay (Same as the CarTek one). The connection to the receiver is made by an 18 pin Terminal Block (Similar to those used in a PC ATX Power supply). We supply the connector with 30cm flying lead as part of the kit.
You connect a 12v and GND to the receiver, then each relay has 2 dedicated wires for NO and COM connection up to 10 amps. Nice and simple.
The receiver unit is 150mm x 76mm x 48mm excluding flanged mounts.
Here's some other fun stuff that the website doesn't mention;
Each button on the Raptor can be set to either a Momentary or Latching action, the flashing mode can be set in combination with this (Momentary Flashing (headlights) or Latching Flashing (Indicators).
The Raptor button plate is an integrated circuit board, made from 3.2mm FR4 and coated in 2 layers of black resist (Not painted).
It's water, Oil and fire resistant (self extinguishing).
The rear of each button is completely covered in a resin filled platic cap, there are no wires on show at all.
All of the transmitter components are housed in the horn press area, so there's no box on the back.
It takes a 3v CR2032 Battery, which can be changed in seconds by twisting of the centre cover cap (No screwdriver involved).
It's taken 3 years of R&D to bring the Raptor to the market. It's been tested solidly on the road, track and in real racing situations. In closed cockpit cars, open cockpit cars, with all types of radio communication equipment to ensure reliability.
Here's the previous version installed into our own Demo / Endurance Race car;
Same build quality, same transmission technology but the Raptor is a bit smaller and doesn't have the box now
It's a beautiful bit of kit for the price and any alternative product is at least £150 more expensive.
Anyway, that's enough shameless plugs from me
Happy to answer any questions on it. It's available to pre-order now and the first batch of deliveries will be early August.
