Both sides of the power distribution on relays 1-6 are fused allowing the board to be used in systems where dc power is
floating with respect to earth. Fuse voltage feedback is compatible with 24 V, 48 V, and 125 V dc applications as well as 120
V and 240 V ac applications.
The following table lists the relationship between fuses, jumpers, relays, and terminals.
