8.2.7 Connection for the configurable output relays

There are 6 relay outputs, except fuel and crank relays which are fixed function, other relays’ function

all can be configured by user.

NOTE:

Terminal #17 is the common port for RL1 to RL6, and it is connected to

power positive.

The output current for each relay can not exceed the rated current of

respective relay; the total output current for 6 relays (from RL1 to RL6) can
not exceed 16A.

A switch or fuse for over current protection must be mounted between

power and terminal #17, the recommended capacity is 16A. In practical
application, controller output will generate instantaneous peak current, you
must consider the peak current when choosing a switch or fuse for over
current protection.
