12VDC Power Output
One or four (VK1100 / VK2100) ports provide 12VDC of power with a total
of 12 or 24 watts. The output can power one or four (VK1100 / VK2100)
independent hardware devices, one or four (VK1100 / VK2100) loops for
connected relay devices, or one or four (VK1100 / VK2100) digital output
devices. If the combined current of the ports exceeds 1A (VK1100) or 2A
(VK2100), the DC Power Overload LED lights orange, an alarm beeps three
times and the ports are turned off. To return power to the ports, power off the
Control Box, unplug all hardware connected to the 12VDC Power Output
ports, power on the Control Box, and then plug in the hardware devices, one at
a time, ensuring the current does not exceed 1A or 2A.
The diagrams on the next three pages show ports on the VK2100. The VK1100
is the same except that it has fewer 12VDC terminal blocks and no I/O ports.
