SMART LOGIC Bypass, TF2218/7E-P and TF2218/7E-S
These smart
bypass relays fit virtually all cars, handle cars with standard or modulated (e.g.
two lamps on one wire) circuitry, and have a low quiescent current.
Interface to the car is via signal wires from the relay; interface
to the trailer is via screw terminals.
Plug-in SMART LOGIC Bypass, TF2218/7EPIN with fog cut-out and “trailer aware” output.
With all the
features of the TF2218/7E, this version has extra functionality: It can, if
required, be fitted so that it cuts out the vehicle’s fog lights when a trailer
is connected; it also has an output that goes live (+12V, protected) when a
trailer is connected.
This can be used, for example, to switch on a parking sensor cut
out.
