Outputs
Powered mechanical relays (0 to 12
depending on model code):
Pre-powered on circuit board switching line voltage. Two, three or four
relays are fused together (depending on model code) as one group, total
current for this group must not exceed 6 A (resistive), 1/8 HP (93 W)
Dry contact mechanical relays (0 to 12
depending on model code):
6 A (resistive), 1/8 HP (93 W)
Dry contact relays are not fuse protected
Pulse Outputs (0 to 12 depending on
model code):
Opto-isolated, Solid State Relay

NOTE on Wi-Fi:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequen-
cy energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
