Base modules are powered from a 9-30VDC source using either the DC jack or screw terminals on
the side of the unit. Sealevel offers several power supply choices to make connection easy (see the
Accessories chapter at the end of this document).
Each SeaI/O product, including the expansion modules, contains an onboard switching regulator
power supply rated for 9-30VDC. For local installations (less than 10‟ apart), expansion unit power
is usually supplied from the Base unit via the pass-through connectors. The number of expansion
modules that can be driven from the Base unit depends on the power source and number/type of
expansion units. Refer to the chart below for power requirements. For expansion modules mounted
remotely (greater than 10‟ apart), separate power is required at each expansion unit.
